Western blot using polyclonal anti-PIF3 antibodies

Total protein from Arabidopsis thaliana (10-20 µg) of 4-d-old dark grown Col-0, pif single, triple and quadruple mutants were extracted with the buffer described in Qiu et al. 2015 and denatured at 95°C for 5 min. were separated on 8 % Bis-Tris SDS-PAGE, and subsequently blotted to Nitrocellulose membrane using wet tank transfer. Blots were blocked with TBS containing 2% non-fat milk at room temperature for 1h. Primary anti-PIF3 antibodies were used in dilution of 1:1000 to TBS containing 2% milk. The incubation time was 14-20 hours at 4°C. After washing 4x5 min. with TBST at room temperature, the blots were incubated with HRP-conjugated secondary antibodies (1:5000) at room temperature for 1h. The blots were washed 4x10 min with TBST again and the signal was detected using the SuperSignal West Dura Extended Duration Substrate (ThermoFisher Scientific).

Chemical inhibition of CCD activity revealed how a ccr2 generated apocarotenoid signal transcriptionally up-regulates POR and PIF3 in parallel to det1-154 during skotomorphogenesis.(A) Transcript levels of PORA, PIF3 and HY5 in WT, ccr2, ccr2 det1-154 and det1-154 etiolated seedlings growing on MS media (+ /- D15). Statistical analysis denoted as a star was performed by a pair-wise t-test (p<0.05). Error bars represent standard error of means. (B), (C) and (D) Representative western blot images showing POR, DET1, PIF3 and HY5 protein levels, respectively. Proteins were extracted from WT, ccr2 and ccr2 det1-154 etiolated seedlings grown on MS media without (control; Ctrl) or with the chemical inhibitor of CCD activity (D15). The membrane was re-probed using anti-Actin antibody as an internal loading control. Lattice-like symbol below POR western (B), represents formation of a PLB in etiolated cotyledons from that genotype and treatment. (E) Model describing how a cis-carotene derived cleavage product, ACS, regulates POR, HY5, PIF3 and PLB formation during skotomorphogenesis. DET1 maintains skotomorphogenesis by post-transcriptionally maintaining a higher and lower PIF3 and HY5 protein levels, respectively. HY5 promotes and PIF3 represses PhANG expression. det1 mutants trigger photomorphogenesis in that they lack POR mRNA transcripts, protein and a PLB. ccr2 generates ACS that enhances POR mRNA transcript and protein levels that enable PLB formation in det1-154. det1-154 restores PLB formation in ccr2 by blocking a signalling pathway acting independent of POR.The DET1-154 peptide is smaller in det1-154 mutant genotypes.(A) Representative western blot image showing the reduced DET1 peptide size in ccr2 det1-154 and det1-154 (59 kDa) compared to WT and ccr2 (62 kDa). Gel electrophoresis of the gel membrane from Figure 7C (electrophoresis for 38 min at 165 volt) was extended for 120 min at 100 volts to resolve the 3 kDa difference in DET1-154 protein size. Under these conditions, the 37 kDa ACTIN peptide and pre-stained ladder were not detected on the membrane. Proteins were extracted from WT, ccr2 and ccr2 det1-154 etiolated seedlings grown on MS media without (control; Ctrl) or with the chemical inhibitor of CCD activity (D15).

Images of seedlings represent are cotyledons are coloured green or yellow to reflect the delay in chlorophyll biosynthesis induced by ACS as evidenced in Figure 6c. De-etiolation of seedlings was performed by transferring 4-d-old etiolated seedlings to continuous light for 3 d to induce photomorphogenesis. Statistical analysis denoted as a star was performed by pair-wise t-test (p<0.05). Error bars represent standard error of means. Ctrl; Control; Ctrl, D15; chemical inhibitor of CCD activity.

Additional information

Additional information Please, do not re-use PIF3 antibody solution after first incubation with your membrane as most of antibody will bind in this step and next result will not be reproducable

PIF3 protein runs at higher MW than expected, as observed previously (Al-Sady et al. 2006). PIF proteins are not that stable, therefore special precautions should be taken during extraction and whole procedure should be performed in as little light as possible (light green light).

Background

Background PIF3 (Phytochrome interacting factor 3) is a transcription factor which acts positively in the phytochrome signaling pathway. It activates transcription by binding to the G box. Subcellular localization is nucleus.
