Interview with Prof. Debabrata Laha

Prof. Debabrata Laha

Dr. Debabrata Laha is a professor at the Department of Biochemistry, Indian Institute of Science (IISc), Bangalore, where his laboratory investigates how inositol pyrophosphate messengers influence plant physiology and adaptation to uncover the molecular processes that enable sessile plants to cope with shifting environmental stresses.

- Please tell us about yourself and your research/institution.

I started my laboratory at the Department of Biochemistry, Indian Institute of Science (IISc), Bangalore during pandemic time, almost 5 years back. IISc is a premiere research institute of India and provides excellent platform for conducting multidisciplinary research. My lab investigates the contribution of inositol pyrophosphate messengers in controlling various aspects of physiology, growth and development and immunity in land plants.

- What motivated you to get into plant science?

Land plants are sessile, yet they must cope with countless stressors to survive. What are the molecular processes that plants have evolved to adapt to an ever-changing environment? Are these molecular mechanisms shared across different clades of land plants? We are very excited to explore the answers to some of these open questions.

- How have you used (Agrisera) antibodies in your research?

I have been using Agrisera antibodies since my PhD time at the University of Tübingen, Germany. I find them to be an excellent resource for the plant science community. In our laboratory, Agrisera antibodies are routinely employed in various experiments. For example, we have used the anti-RGA (DELLA) antibody to investigate the potential role of inositol pyrophosphate messengers in regulating DELLA protein levels in Arabidopsis thaliana (Rana et al., Nat Chem Biol 2025).

Interview with Assistant Prof. Ivan Radin

Assistant Prof. Ivan Radin

Dr. Ivan Radin is an Assistant Professor in the Plant and Microbial Biology Department at the University of Minnesota. Their research focuses on understanding how plants and green algae perceive mechanical forces through organellar mechanosensing, with an emphasis on mechanosensitive ion channels in vacuoles and chloroplasts.

- Please tell us about yourself and your research/institution.

I am an Assistant Professor at the Plant and Microbial Biology Department at the University of Minnesota. My lab is interested in how organellar mechanosensing (the ability to sense mechanical force) has evolved within the green lineage (land plants and green algae). Our current goal is to understand the function of vacuolar and chloroplastic mechanosensitive ion channels from Arabidopsis, moss Physcomitrium, and green alga Chlamydomonas.

- What motivated you to get into plant science?

Initially, it was a bit of luck. As an undergraduate student, I was looking for research opportunities when I got an opportunity to work in a plant lab. I immediately fell in love with plant biology, and since then, I have been pursuing plant research. To this day, I am fascinated by the complexity of plant cells and their ability to respond to their environment. Plants are much more complex and sophisticated than most people realize.

- How have you used (Agrisera) antibodies in your research?

I used a lot of Agrisera cellular compartment marker antibodies for Western blots during my grad school. Now in my lab, the Agrisera antibodies are the first new antibodies we bought. More specifically, we are using antibodies against fluorescent protein tags.

- Any further comments?

I very much appreciate the Agrisera practice of always testing their new products with the help of the plant research community before releasing them for sale. This significantly increases my confidence in their antibodies.

Interview with Prof. Łucja Kowalewska

Prof. Łucja Kowalewska

Dr. Łucja Kowalewska is an Assistant Professor at the Faculty of Biology, University of Warsaw, where she serves as the Head of the Department of Plant Anatomy. She specializes in plastid membrane dynamics and structural biology, using advanced microscopy, computational analysis, and biophysical approaches to study organelle nanomorphology. Her research focuses on how biological membranes self-organize into complex three-dimensional structures, revealing how their architecture directly contributes to biological function.

- Please tell us about yourself and your research/institution.

I am an Assistant Professor at the Faculty of Biology, University of Warsaw, where I serve as Head of the Department of Plant Anatomy and Cytology and Chairwoman of the Council of the Institute of Experimental Plant Biology and Biotechnology. As a plant cell biologist, I specialize in plastid membrane dynamics and structural biology, applying advanced microscopy, computational methods, and biophysical principles to understand organelle nanomorphology.

Our research focuses on nanomorphology as a critical level of biological membrane organization, exploring how membrane structure itself serves as a direct source of biological function. We investigate the fascinating world of membrane self-organization, particularly the formation of complex periodic arrangements, with an emphasis on cubic membranes that resemble triply periodic minimal surfaces, known in differential geometry and topology. Through an interdisciplinary approach that bridges biology, biophysics, and topology, we aim to understand how biological membranes self-organize into complex, three-dimensional periodic structures and the molecular mechanisms that govern these transformations.

- What motivated you to get into plant science?

My path into plant science began early during my bachelor's studies in biotechnology, when I instantly decided to focus on plants. I was deeply interested in cell biology, but I chose to explore this field using plant models rather than working with animal material, as I didn't want my daily work to involve animal suffering—although I certainly understand, appreciate, and support the necessary use of animal studies for both basic science and medicine.

My simultaneous interest in visual arts drew me to organelle ultrastructure, where I quickly realized that plastid membrane networks represent the most complicated and beautiful membrane arrangements known in nature. Yet, we understand little about the mechanisms behind their formation. Today, I don't necessarily think of myself as just a plant biologist, but rather as a cell biologist who is fortunate to work with the best existing model—plastid membranes—to understand the relationship between membrane nanomorphology and biological function, as well as the molecular basis of these complicated self-organizing shapes.

- How have you used (Agrisera) antibodies in your research?

Agrisera antibodies are crucial to my group's work and have helped us verify many hypotheses, as they are always reliable materials supported by the excellent guidance of Dr. Joanna Porankiewicz-Asplund. Agrisera is also remarkably open to discussing new antibodies that can truly help verify novel ideas and significantly advance our projects.

I believe the most important outcome from using Agrisera antibodies was proving the presence of CURT1 proteins in prolamellar bodies of etiolated seedlings—something that had been overlooked in previous proteomic studies of this structure. This discovery greatly enhanced our understanding of diamond-type organization formation, proving the role of curvature-inducing proteins in forming this special geometry. This finding was pivotal in demonstrating how specific proteins contribute to the complex three-dimensional membrane architectures we study.

- Any further comments?

My relationship with Agrisera spans over a decade and holds special significance in my scientific journey. My first poster prize, received as a PhD student during a Photosynthesis Research conference, was an Agrisera prize that included a Z-scheme poster signed by Govindjee with congratulations. I still have this poster in my office, and it serves as a constant reminder of that intensive but deeply satisfying time during my PhD journey. It also highlights how Agrisera has supported my research for more than 10 years now.

The collaborative relationship with Agrisera exemplifies the kind of partnership that advances science—one where a company not only provides products but also actively engages with researchers to develop tools that can push the boundaries of our understanding. This support has been invaluable in our interdisciplinary approach to unraveling the mysteries of biological membrane organization.

Interview with Prof. Simone Landi

Prof. Simone Landi

Simone Landi is an Associate Professor at the University of Naples Federico II in Italy, the world’s oldest public university, founded more than 800 years ago. Their research focuses on how plants respond to abiotic stress and on enzymes involved in both central and secondary metabolism.

- Please tell us about yourself and your research/institution.

I am Associate Professor at University Federico II of Napoli (Italy) who received a PhD in Applied Biology at the University of Naples, Federico II in 2016, and I was research associate at National Research Council of Italy, Institute of Biomolecular Chemistry from 2018 to 2019. My institution represents the most ancient non-religious University in the World (801 years old) funded by Federico II of Svevia. My research activity focuses on the response of plants to abiotic stresses and on the enzymes related to central and secondary metabolism. We worked both on model organisms and on recombinant proteins using classical and advanced approaches.

In my opinion, plant science is a cornerstone of research topics. The use of plants and photosynthetic organisms in general is of great interest in both basic science and biotechnological applications.

- How have you used (Agrisera) antibodies in your research?

We primarily use Agrisera as antibodies for Western blotting. Almost all of our antibody collection comes from Agrisera. We find them to be effective for plants and that the catalog is so extensive that we can almost always find what we're looking for. We also find it very useful to collaborate in exchanging untested antibodies that can be used experimentally.

Plant chloroplast

Interview with Dr. Tatjana Kleine

Dr. Tatjana Kleine

Dr. Tatjana Kleine, principal investigator in the Plant Molecular Biology Group at Ludwig-Maximilians-Universität München (LMU Munich), studies how chloroplasts communicate with the rest of the cell during stress. Her work focuses on organellar gene expression and retrograde signalling, using Arabidopsis as a model system. In this interview, she shares how her curiosity for nature began at an early age, inspired by observing a small forest lake ecosystem at school—an experience that sparked a lifelong fascination with plants and their biology.

- Please tell us about yourself and your research/institution.

My name is Tatjana Kleine, and I am a principal investigator in the Plant Molecular Biology Group at Ludwig-Maximilians-Universität München (LMU Munich). My research is dedicated to understanding how chloroplasts—the cellular organelles responsible for photosynthesis—communicate with the rest of the cell to regulate development and respond to environmental stress.

I am particularly interested in organellar gene expression and the remarkable process of retrograde signalling, whereby chloroplasts send signals to the cell nucleus to influence gene activity. Using model plants such as Arabidopsis thaliana, my work seeks to uncover the molecular networks that enable plants to adjust to changes in light, temperature, and other environmental challenges.

By advancing our knowledge of these adaptive strategies, I hope to contribute to a deeper understanding of how plants thrive in dynamic environments—a question of growing importance in the face of climate change and the need for sustainable agriculture.

- What motivated you to get into plant science?

From an early age, I was fascinated by the natural world—one of my fondest memories from school is a half-year project in which I observed an ecological niche: a tiny lake nestled within a forest and its surrounding environment. I have a lifelong curiosity about plants, which I paired with a growing enthusiasm for molecular biology, especially after discovering that it was possible to study and even manipulate plants at the molecular level.

Plants have always captured my imagination. They are indispensable to all life on Earth, providing us with food, oxygen, and vital raw materials. Their extraordinary diversity, resilience, and evolutionary ingenuity offer endless opportunities for exploration and discovery. Even as I focus on basic research, I am driven by the hope of making a small but meaningful contribution to our understanding of plant life.

- How have you used (Agrisera) antibodies in your research?

I believe that anyone interested in plant biology either uses—or should consider using—Agrisera antibodies. I initially turned to their products for the detection of photosynthetic proteins, but as their portfolio has continued to expand, I now rely on Agrisera antibodies also to detect and quantify my proteins of interest, including those with nuclear localization—but also to confirm protein localization, provide reliable loading controls, and analyse protein dynamics under various experimental conditions. Agrisera’s antibody versatility and high quality have made them an indispensable resource in my research and for the broader plant science community.

- Any further comments?

I spent three wonderful years as a postdoctoral researcher at the UPSC in Umeå, located near Vännäs, where Agrisera is based. I have extremely fond memories of my time there and grew to love Västerbotten—it truly is a special place. During this period, I had the pleasure of getting to know Joanna and her team. I greatly appreciate their dedication as well as their constant and prompt support. Thank you very much!

Interview with Assoc. Prof. Alizée Malnoë

Assoc. Prof. Alizée Malnoë

Dr. Alizée Malnoë is an Associate Professor in Plant Biology at Indiana University in Bloomington, USA. Her lab investigates how plants defend themselves against damage from too much sunlight, a process essential for their survival. After several years in Sweden at Umeå Plant Science Centre, Dr. Malnoë moved her group to Bloomington in 2024, continuing her research into photosynthesis and photoprotection.

- Please tell us about yourself and your research/institution.

I am an Associate Professor in Plant Biology at Indiana University in Bloomington, USA. Our lab research how plants protect themselves from sunburn. We moved in April 2024 from Umeå Plant Science Centre in Sweden. There, it was an amazing perk to meet and connect with Joanna and other Agrisera team members in person several times throughout the year, and receive our reagent orders on the same day they were ordered!

- What motivated you to get into plant science?

I wanted to make biofuel from renewable resources, I started my research experience with the microalga Chlamydomonas (affectionately called Chlamy) and studying photosynthetic electron transport for hydrogen production. I realized that much basic science is needed to understand and optimize natural processes, and how thrilling the job of an academic scientist is in investigating how nature works. I've since studied photoprotection mechanisms in the plant model Arabidopsis, with Kris Niyogi at UC Berkeley during my postdoctoral training, and now with my own group. Algae, plants, are so important for our human lives: they give us food, fiber, feed, fuel and oxygen!

- How have you used (Agrisera) antibodies in your research?

Agrisera is THE provider of antibodies for photosynthetic research, I learned alongside Catherine de Vitry during my PhD at IBPC Paris how to analyze protein content in different mutant Chlamy strains. IBPC is one of the birthplaces of many chloroplast protein antibodies sold by Agrisera, it felt there was no limit to the questions we could answer, they had them all!

A notable moment during my postdoctoral training was when we had just found an unknown protein to be involved in photoprotection now named relaxation of qH1 (ROQH1). We were about to design an antibody but I searched the Agrisera website to see if they might already have an antibody against it (this was a long shot) but they did! These was thanks to Agrisera's work in collaboration with Sabeeha Merchant and Arthur Grossman's labs where they had generated antibodies of several "greencut" proteins, those that are conserved throughout the green lineage but not present or poorly conserved in non-photosynthetic organisms.

- Any further comments?

We're tremendously thankful for Agrisera's products and Joanna's help troubleshooting and answering our numerous immunoblots' related inquiries.

Interview with Dr. Kirk J Czymmek

Dr. Kirk J Czymmek

Dr. Kirk J Czymmek serves as Principal Investigator and Director of the Advanced Bioimaging Laboratory at the Donald Danforth Plant Science Center. His work focuses on the development and application of advanced microscopy techniques—including light, x-ray, and electron microscopy, as well as super-resolution and cryo-methodologies—to address fundamental questions in plant-microbe interactions. The aim is to use advanced imaging to help uncover how plants respond, guiding new strategies to protect yields and ensure food security.

- Please tell us about yourself and your research/institution.

I am a microscopist and specialize in plant-microbe interactions as a Principal Investigator and Director of the Advanced Bioimaging Laboratory at the Donald Danforth Plant Science Center. In my current role, I apply and develop advanced microscopy tools in plant science dedicated to producing more nutritious food and improving the environment. I received my doctorate in Botany and Plant Pathology at Michigan State University and did a post-doctoral position at the DuPont Company in CR&D Plant Molecular Genetics group before a career encompassing both academia and industry. My expertise in most forms of light, x-ray and electron microscopy, including super-resolution microscopy, cryo-techniques and correlative microscopy has enabled me to develop and apply cutting-edge microscopy tools for imaging cells, tissues and biomaterials.

- What motivated you to get into plant science?

My family grew cash crops, including alfalfa, timothy, and high-quality hay for the racehorses. As the middle child of seven on the farm, I was a laborer. It was hot, hard work, but the free-range childhood inspired my early interest in science. I went to college with a focus on biology and the courses I enjoyed the most were my plant systematics class, microbiology, and electron microscopy. I’m a very visual person, and looking through the eyepieces of any microscope opened a whole new world to me with seemingly unlimited opportunities for discovery.

As the world’s warming continues, plants will be more stressed and vulnerable. Under higher humidity and warmer environmental conditions, fungi and other pathogens thrive, and diseases once limited to the tropics continue to spread. Disease resistance and crop protection strategies are important for plants so we can figure out how to grow more food in challenging conditions. We need more productivity to feed the world. Advanced imaging is a very important tool to help us solve these challenges.

- How have you used (Agrisera) antibodies in your research?

Both over my career and in ongoing research, Agrisera is my first stop for a trusted source to find high quality antibodies (e.g. for cell walls, cytoskeleton, organelles, to name just a few) for molecular and imaging plant applications. What I especially like is their comprehensive documentation on what approaches, citations and/or protocol overviews a particular antibody has been demonstrated and suitable for. This ultimately saves a lot of time and money without having to guess if it works or not.

- Any further comments?

Joanna Porankiewicz-Asplund is an OUTSTANDING resource if you are trying to get technical guidance and support, either before you start or already working with Agrisera antibodies. In addition, if you have used an antibody and it worked great, let her know and she can share exemplary data for others in the plant community.

Interview with Prof. Alejandra A. Covarrubias

Prof. Alejandra A. Covarrubias

Dr. Alejandra A. Covarrubias is a professor in the Plant Molecular Biology Department at the Biotechnology Institute of the Universidad Nacional Autónoma de México (UNAM), Campus Morelos. She has dedicated her career to exploring the molecular mechanisms that underlie plant responses to environmental stress, with a strong focus on water scarcity. In this interview, Dr. Covarrubias reflects on her scientific journey and highlights the critical role of plant research in achieving sustainable agriculture.

- Please tell us about yourself and your research/institution.

I am currently a full professor in the Plant Molecular Biology Department at the Biotechnology Institute of the Universidad Nacional Autónoma de México (UNAM), Campus Morelos. I completed all my higher education in UNAM, Mexico City Campus. I earned a bachelor’s degree in Biological Chemistry, followed by MSc and PhD degrees in the Biomedical Sciences program.

My graduate research focused on applying recombinant DNA technology to study the genetic regulation of bacterial nitrogen metabolism. During my thesis work, I isolated and characterized the first gene for the glutamine synthetase, a central enzyme in nitrogen metabolism across all organisms, and other genes involved in its regulation. As part of my graduate training, I spent two years in Dr. Herbert Boyer’s lab at the University of California, at San Francisco. There, I learned the fundamentals of recombinant DNA and cloning from the leading scientist in the field. This experience had a profound impact on my career, giving me the opportunity to learn from outstanding mentors and gain exposure to diverse scientific and biotechnological approaches. I also witnessed the early, often controversial discussions surrounding the use of recombinant DNA.

After returning to Mexico, I completed my PhD and received my first job offer from the Biomedical Research Institute at UNAM, where I continued studying the genetic control of nitrogen metabolism. Two years later, I was invited to join to the newly created Nitrogen Fixation Research Center (CIFN)in Cuernavaca, Morelos - the first UNAM initiative to decentralise scientific research. At this point, the idea was to start a research group working on plant molecular biology, a field that taken root in Mexico. This marked a pivotal moment in my career, as it. represented both a significant challenge and an exciting opportunity to contribute to scientific development in my country. I was privileged to receive a fellowship from the Rockefeller Foundation, which allowed me to train in plant biology. I was fortunate to be accepted into Dr. Virginia Walbot’s lab in the Biological Sciences Department at Stanford University, to whom I am very grateful. It was there that fell in love with plants and discovered a fascinating and entirely new world. Two years later, following changes in the development plan of the CIFN, the entire plant research group moved to the Genetic Engineering Research Center (now the Biotechnology Institute), where we established the new Plant Molecular Biology Department.

- What motivated you to get into plant science?

There were several reasons that led me to pursue plant science. I recognized the urgent need for our country to establish research groups focused on various aspects of plant molecular biology aiming to build the knowledge base necessary to better understand the plant world and thereby contribute to more sustainable agriculture. On a more personal level, I was particularly intrigued by how plants respond to water scarcity. After speaking with various Mexican agronomist and crop improvement specialists, it became clear that this issue was both serious and urgent. During my long hours in the library, I realized that plants possess remarkably efficient mechanisms to sense, adjust and adapt to changing environmental conditions – a phenomenon that has continued to fascinate me ever since.

- How have you used (Agrisera) antibodies in your research?

My first contact with Agrisera arose from our need to get antibodies against specific plant proteins involved in the plant response to water deficit, which we were studying at that time. Although we were able to generate our own antibodies, issues at our Institute’s facility, created an urgent need for reliable alternatives. Agrisera came to the rescue. I reached out Joanna Porankiewicz, and we received a prompt, professional service along with high-quality antibodies. Since then, Agrisera has become our preferred source for antibodies.

- Any further comments?

Thank you Joanna Porankiewicz-Asplund. I hope Agrisera continues to support our research through its expertise in antibody production and protein detection techniques.

Interview with Prof. Wolfgang Schröder

Prof. Wolfgang Schröder

Dr. Wolfgang Schröder is Professor Emeritus at Umeå Plant Science Center. His research group investigates the structure and function of the photosynthetic protein complex PSII. Using cryo-electron microscopy as structural imaging method the research team aims to investigate how PSII undergoes conformational changes to protect against damage from intense light, as well as how plants can selectively disconnect parts of the photosystem to minimize energy loss and mitigate light-induced stress.

- Please tell us about yourself and your research/institution.

I made my PhD in Lund University at the department of biochemistry with Hans-Erik Åkerlund. After that I made a PostDr stay at CNRS outside Paris and a second PostDr in Berlin in the group of Gernot Renger. After that I returned to Sweden and became Docent at Stockholm University in the department headed by Bertil Andersson. In 2002 I moved to Umeå where I became professor. Since 2024 I am emeritus professor at Umeå Plant Science Center.

- What motivated you to get into plant science?

I was persuaded by Per-Åke Albertsson at biochemistry in Lund to make a bachelor exam work using two-phase extractions on plant material. After that I was hooked into plant biochemistry, as I realized the great advantage of plant-material which have few ethical or permission considerations.

- How have you used (Agrisera) antibodies in your research?

Throughout my carrier I have used antibodies from Agrisera, they have been crucial for identifying both new and old proteins. My first antibody produced was against a previous unknown low molecular protein in Photosystem II. This serum was the strongest sera I ever have obtained and I was happy that the protein was named PsbW.

- Any further comments?

Helpful and friendly personnel always prepared to help with troubleshooting.

Interview with Dr. Pushan Bag

Dr. Pushan Bag

Dr. Pushan Bag received his PhD degree from Umea Plant Science Centre in Sweden, and is now a Postdoctoral Researcher at the University of Oxford. He is a part of Prof. Paul Jarvis’s lab, in the field of chloroplast protein transport. His work aims to understand how proteins are imported into chloroplasts and how this process varies during different developmental stages, with the goal of improving crop performance.

- Please tell us about yourself and your research/institution.

My name is Pushan Bag, and I’m a Human Frontiers Science Program research fellow at the Department of Biology, University of Oxford. I work in Prof. Paul Jarvis’s lab, in the field of chloroplast protein transport. My current research focuses on how proteins are imported into chloroplasts, particularly how this process changes during different developmental stages. I'm especially interested in the structural biology of these transport machineries. The long-term goal is to engineer the protein transport machinery to influence plant development, which could have significant implications for improving crop performance.

Since protein transport into chloroplasts is heavily light-dependent, it’s clear that this process is directly or indirectly regulated by photosynthesis. During my PhD, I worked extensively on photosynthesis, which gave me a strong foundation in chloroplast energy metabolism. Now, I aim to integrate that expertise with my current work to explore how chloroplast energy status and redox metabolism influence—and are influenced by—organelle biogenesis and development. Ultimately, I hope to build a unified understanding of how chloroplasts function and adapt under different environmental and developmental conditions.

This field is also incredibly fascinating from an evolutionary perspective. Chloroplast protein transport is believed to have evolved from ancient bacterial toxin ejection systems. As life on Earth progressed from unicellular to multicellular organisms and eventually to higher plants, these primitive systems were repurposed—from ejecting toxins to importing proteins. One hypothesis is that, following the endosymbiotic origin of chloroplasts from cyanobacteria, most of the endosymbiont’s genes were transferred to the host nucleus, which then forced the evolution of a protein import system from what was originally an ejection system. But we don’t yet know exactly how this transition occurred—or if it happened in that way at all.

To shed light on this question, I’m examining the structure of these protein transporters across organisms throughout the evolutionary tree. By doing so, I hope to understand how this transformation took place. This research could also provide insights into mitochondrial evolution, as both chloroplasts and mitochondria originated via endosymbiosis. Understanding one may help us better understand the other.

- What motivated you to get into plant science?

Well, to be honest, I wasn’t very enthusiastic about plant science early in my academic journey. During my bachelor’s studies, I focused on microbiology, physics, and chemistry. I still remember the first time I saw the Z-scheme of photosynthesis in a textbook—I thought it looked too complicated and skipped that chapter altogether!

Later, I pursued a Master’s in Molecular Microbiology, which wasn’t plant-focused either, although it was offered by the Department of Plant Sciences at the University of Hyderabad. My entry into plant biology was more of a happy accident. Due to lower first-semester grades, I had limited options for my master’s thesis lab and ended up in a plant biology lab that no one else from my program had chosen. That turned out to be a blessing in disguise: I had a great experience and even got a good paper out of it. That was the moment I got properly introduced to plant science—and since then, it's been green all the way!

After my Master’s, I joined Prof. Rajagopal’s lab, where I first started working with chloroplasts and photosynthesis. I began to wonder: when we treat plants in the lab and observe how they respond, how does that compare to how they naturally behave in the wild? That curiosity led me to do my PhD with Prof. Stefan Jansson in Umeå, working on conifers in natural and extreme conditions, which felt like a very natural progression. From there, moving into protein transport with Prof. Jarvis and thinking about how we can engineer plants for agriculture has been a very fulfilling path.

And looking back on it all, I’m reminded of that quote from Steve Jobs: “You can’t connect the dots looking forward; you can only connect them looking backwards.” At the time of choosing my Master’s lab, I had absolutely no idea what I was doing—just taking the only open opportunity. And now here I am, giving an interview to Agrisera about plant protein antibodies. That’s the beauty of the journey.

- How have you used (Agrisera) antibodies in your research?

The first time I used Agrisera antibodies was in Prof. Rajagopal’s lab—probably for a western blot of Photosystem II subunit A (PsbA). Before that, I hadn’t even heard of Agrisera. But once you get into photosynthesis research, you quickly realize how essential Agrisera is, especially given their extensive collection of antibodies targeting photosynthetic proteins.

During my PhD in Umeå, I got to work closely with Agrisera for multiple reasons. First, they were part of my Marie Skłodowska-Curie Horizon 2020 EU project. Second, in Prof. Jansson’s lab, many light-harvesting complex antibodies were co-developed with Agrisera. I also had a particularly rewarding experience working with spruce and pine, which required antibody optimization. Agrisera was extremely helpful and responsive throughout that process. We even developed spruce-specific Lhcb1 antibodies in collaboration with them, and the whole process was smooth and enriching.

Now that I’m in the UK, I’m still planning to design more antibodies with Agrisera. Beyond their research tools, I also want to highlight the educational posters and illustrations they create. Those were incredibly helpful during my PhD and even contributed to how I structured my thesis. It really shows how a company can go beyond commercial products to play an educational and academic role in the scientific community.

- Any further comments?

I truly value the role of well-characterized molecular tools in advancing plant science, and Agrisera has been a key part of that journey for me. As the field moves toward more integrative and synthetic approaches—combining insights from photosynthesis, organelle biology, and systems biology—having reliable, specific, and customizable reagents is more critical than ever. I’m particularly excited about the potential to unravel how chloroplast energy status regulates development and function, and how that understanding can be applied to improve crop productivity in a changing world.

Light-induced structural changes in thylakoid membranes, revisited in the recent publication

In the recently published article, Wójtowicz et al. (2025). Shrink or expand? Just relax! Bidirectional grana structural dynamics as early light-induced regulator of photosynthesis, an international group of researchers challenged the traditional binary model of light-induced thylakoid dynamics. They discovered and described three-phase response, using high-resolution structural approaches like: transmission electron microscopy, confocal microscopy with 3D modeling, and small-angle neutron scattering as well as spectroscopic and electrophoretic analyses of the photosynthetic apparatus in two model species: Arabidopsis thaliana and Ficus elastica.

Selected antibodies to proteins of Photosystem I (PSI) and Photosystem II (PSII) antennae (Lhca1, Lhcb2, Lhcb4, and Lhcb5) and core proteins (D1 and PsaB), phosphorylated variants of D1 and Lhcb2 proteins and Atpb subunit of ATP synthase were used in this study.

Agrisera antibodies used in this work were:
Lhcb1-P, Lhcb2, Lhcb2-P, Lhcb4, Lhcb5, Lhca1, PsbA, PsbA-P, AtpBeta, PsaB, acetylated lysine

Interview with Prof. Ru Zhang

Prof. Ru Zhang

Dr. Rue Zhang is a Principal Investigator at the Donald Danforth Plant Science Center in St. Louis, Missouri. She leads a lab focused on understanding how photosynthetic cells respond to heat stress to improve crop resilience in a warming climate. Using model plants and algae, her lab focuses on photosynthesis—one of the most heat-sensitive yet vital processes in plants.

- Please tell us about yourself and your research/institution.

I am an Associate Member and Principal Investigator at the Donald Danforth Plant Science Center in St. Louis, Missouri, USA. My lab studies how photosynthetic cells respond to abiotic stresses, especially high temperatures, by using both green algae (mainly Chlamydomonas reinhardtii) and land plants (mainly Setaria viridis) as models. Global warming increases the frequency, intensity, and duration of high temperatures, which impair plant growth and reduce crop yield. To engineer crops with improved thermotolerance, it is imperative to understand how photosynthetic cells sense and respond to high temperatures. Many pathways in plants can be affected by high temperatures, and we focus on photosynthesis, a key driver for plant growth and food production but one of the most heat-sensitive functions in plants.

During my PhD training at the University of Wisconsin-Madison, I worked with Dr. Thomas Sharkey studying the effects of high temperature on photosynthesis in leaves of Arabidopsis and tobacco plants. During my postdoctoral training with Dr. Martin Jonikas and Dr. Arthur Grossman at the Carnegie Institution for Science, Stanford, I continued to investigate photosynthesis by developing high-throughput genotyping and quantitative phenotyping tools in the eukaryotic, unicellular green alga Chlamydomonas reinhardtii to identify photosynthesis-deficient algal mutants on a genome-wide scale. In October 2016, I started my own lab at the Donald Danforth Plant Science Center.

Founded in 1998, the Donald Danforth Plant Science Center is a nonprofit research institute with a mission to improve the human condition through plant science. Research, education and outreach aim to have an impact at the nexus of food security and the environment, and position the St. Louis region as a world center for plant science. The Center’s work is funded through competitive grants from many sources, including the National Science Foundation, National Institutes of Health, U.S. Department of Energy, the Gates Foundation and through the support of individuals and corporations. Learn more at danforthcenter.org.

- What motivated you to get into plant science?

I feel very happy when I am around plants, starting at a young age. As an undergraduate researcher in Dr. Ningning Wang’s lab at Nankai University in China, I participated in the generation of transgenic micro tomatoes with improved nitrogen uptake efficiency. I loved the smell of tomatoes and all of the green colors in our plant growth room. To me, taking care of my plants was like taking care of my babies. I called the plants I grew my “tomato babies”. It was fascinating to see my transgenic micro tomato plants having improved resistance to low nitrogen. Pursuing plant science quickly became a clear path for me.

- How have you used (Agrisera) antibodies in your research?

We use Agrisera antibodies frequently, mostly proteins involved in photosynthesis or chloroplast biology.

- Any further comments?

Agrisera is not only a great company that produces high quality antibodies but also closely integrates into the plant science communities. My office has several photosynthesis-related graphs supported by Agrisera. Dr. Joanna Porankiewicz-Asplund is outstanding and patient in answering many questions from us about western troubleshooting and Agrisera antibodies. Joanna also led a great online workshop about western at our institution. Thanks a lot, Joanna! Agrisera, Happy 40th Anniversary!

What links Agrisera antibodies to photosynthetic proteins and restoring anabolism of myocardial injury

A very interesting publication by Li et al. A Photophosphorylation Nanobot for Restoring Anabolism of Myocardial Injury, was published in The Journal of the American Chemical Society, in June 2025 issue. Considering high risk of mortality worldwide and due to limited capacity for self-repair after myocardial injury, self propelled nanobots which can target the heart and improve intracellular ATP concentration which leads to restoration of cellular metabolism and repair of myocardial injury, are a promise for the future treatment.

The following Agrisera antibodies to photosynthetic proteins were used to verify this approach:

Interview with Prof. Andreas Hiltbrunner

Prof. Andreas Hiltbrunner

Dr. Andreas Hiltbrunner is a professor for Molecular Plant Physiology at the University of Freiburg, Germany. He earned his PhD at ETH Zürich and then moved to University of Freiburg for postdoctoral research on light signalling and phytochromes. Dr. Hiltbrunner has dedicated his career to investigating the complexities of how plants perceive and respond to light. What motivates him is the importance of understanding plant responses to the environment, to ensure sustainable agricultural production in the future.

- Please tell us about yourself and your research/institution.

During my PhD at ETH Zurich, I investigated the molecular mechanisms of protein import into chloroplasts. For my postdoc, I then moved to the University of Freiburg, Germany, where I became interested in how plants sense the light environment and how phytochromes, an important class of photoreceptors in plants, are involved in this process. When I started my own lab as an independent group leader at the Centre for Plant Molecular Biology (ZMBP), University of Tübingen, Germany, I continued working on light signalling and phytochromes, and also began investigating how phytochromes and light signalling evolved in land plants. Since 2012, I have been Professor of Molecular Plant Physiology at the University of Freiburg, Germany, where I have continued to focus on understanding how phytochromes function at the molecular level, how downstream signalling pathways link light activation of phytochromes to changes in gene expression, and how the evolution of light signalling enabled plants to colonise land.

- What motivated you to get into plant science?

I have always been fascinated by plants, and from the beginning of my studies, it was clear to me that I wanted to work with plants. Plants feed the world, and it is therefore essential that we understand how they respond to changes in the environment, including those driven by climate change, if we are to ensure sustainable agricultural production in the future. However, the projects in our lab fall within the field of basic research, and I feel very privileged to have the freedom to investigate questions that are driven by curiosity and may not have an immediate application. Yet, applied research relies on discoveries made in basic science, and I am confident that understanding the fundamental principles of phytochrome action in model plants such as the seed plant Arabidopsis thaliana or the moss Physcomitrium patens will eventually contribute to practical applications.

- How have you used (Agrisera) antibodies in your research?

Antibodies to detect phytochromes (phy) and proteins involved in phytochrome downstream signalling are essential tools in our research (e.g. for immunoblotting or Co-IP). When our stocks of custom-made antibodies against phyA and phyB, the two primary phytochromes in seed plants, were used up, we needed to find a replacement. Fortunately, antibodies specific to phyA and phyB provided by Agrisera reliably detected the respective phytochromes. This resolved our issue, and we are grateful for this valuable resource. In addition, we are using several Agrisera antibodies against factors in involved in light signalling for immunoblotting.

- Any further comments?

We have tested several antibodies provided by Agrisera, and I really appreciate that – unlike many other companies – Agrisera actively invests in plant research. After several years of email communication, I finally met Joanna in person at a conference last year, which I greatly enjoyed. We were also glad to have Agrisera’s support for a conference at our institute this year, including the generous donation of a free antibody as a poster prize. Tack så mycket!

Interview with Prof. Emilio Gutiérrez

Prof. Emilio Gutiérrez

Dr. Emilio Gutiérrez is a professor and group leader at the Plant Biology and Biochemistry institute, a Joint Centre of the University of Seville (USE) and the Spanish National Research Council (CSIC). His research group explores the key role of stress granules (SGs) in plant stress response. Their goal is to understand the molecular pathways underlying formation of SGs and how the formation promotes stress resistance and cell survival in plants.

- Please tell us about yourself and your research/institution.

I am a group leader at the Plant Biology and Biochemistry institute, a Joint Centre of the University of Seville (USE) and the Spanish National Research Council (CSIC). The IBVF is specialized in the study of phototrophic biology in a broad sense, with the distinctive feature of developing research with all types of oxygenic photosynthetic organisms: cyanobacteria, algae and plants. The research of my group is focused on the understanding the key role stress granules (SGs) in plant stress response. SGs are phase-separated bimolecular condensates formed by proteins and mRNAs assembled in response to stress. The formation of SGs minimizes stress-related damage and promotes cell survival, although the molecular mechanisms underlying pro-survival effects of SGs remain to be established. In contrast to the prominence of research on stress granule in animal and yeast models, in plants, SGs have only received limited attention. Our goal is to establish a profound conceptual and experimental framework allowing us to understand the molecular pathways underlying formation of SGs in plants, which will be used as a basis to finally demonstrate how the formation of these condensates promotes stress resistance and cell survival in plants.

- What motivated you to get into plant science?

Since I was a child, I have been fascinated by the plant world. I am curious to learn how a sessile organism can perceive, respond to, and defend itself against external stimuli, adapting to an increasingly hostile environment. This curiosity drives me to explore the intricate mechanisms that allow plants to survive and thrive despite the challenges they face. Understanding their resilience not only deepens my admiration for them but also fuels my passion for research.

- How have you used (Agrisera) antibodies in your research?

Agrisera is making a significant contribution for the plant science community by developing a wide range of antibodies targeting plant proteins. Protein detection by antibodies is a crucial tool for advancing scientific research. Before Agrisera, there was no company dedicated exclusively to the development of antibodies against plant proteins, filling a vital gap in the field.
