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.

- 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:

Agrisera supported Spanish Society of Plant Biology meeting and Plant Nitric Oxide (PNO) conferences

This week, Agrisera supported the following conferences:

Iberian Plant Biology 2025, held between 1st-4th of July, in Murcia, Spain. This meeting is organized on behalf of the Spanish and Portuguese Plant Biology Societies was a celebration of the 50th anniversary of the Spanish Society of Plant Biology and XIX Spanish-Portuguese congress on plant Biology. The motto of the meeting will be "Plants for a sustainable world".

Plant Nitric Oxide International Meeting (PNO), held between 9th-11th of July, online. The advances in the biology and chemistry of reactive nitrogen species (RNS) were the focus of this meeting. The following topics were covered: Nitric oxide (NO) and its interaction with other reactive species, the physiological and molecular roles of RNS in plants and the crosstalk between reactive oxygen species (ROS) and RNS.

Interview with Prof. Viktor Žárský

Prof. Viktor Žárský

Dr. Viktor Žárský founded the Laboratory of Cell Biology at the Institute of Experimental Botany, Czech Academy of Sciences. He also serves as a professor at the Department of Experimental Plant Biology, Charles University in Prague. His research primarily explores plant cell polarity and morphogenesis, focusing on the role of small GTPases and their effectors within the endomembrane system.

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

I established the Laboratory of cell biology at the Institute of experimental botany, Czech academy of sciences and am at the same time professor at the Department of experimental plant Biology, Charles University in Prague. My research focuses on the biology of plant cell polarity and morphogenesis/development regulated by small GTPases and their effectors in the endomembrane system, especially vesicle tethering complex exocyst and early land plants evolution.

- What motivated you to get into plant science?

As a child I was fascinated by microscopy and as a high school student I got interested in algae - so that algology was my entry point into plant cell and developmental biology.

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

In our research we do not only use Agrisera antibodies, but in collaboration with Agrisera we successfully developed two antibodies against core exocyst complex subunits. From our efforts to develop antibodies we can say that the collaboration with Agrisera was very useful.
