Figure 2.

LHCSR1 protein levels and photosynthetic properties under radiation ranging from UV-A to UV-B. Wild-type cells were treated with 0.25 μmol photons/m²/s of monochromatic UV light of different wavelengths, as indicated, for 3 h. A, Antibodies against ATPB or LHCSRs (recognizing both LHCSR1 and LHCSR3) were used for immunoblotting analysis. LHCSR3-P represents LHCSR3-phosphorylated. The ATPB protein was used as a loading control. Representative immunoblots from one of three replicated experiments are shown, each performed using different biological samples. B, Photosynthetic (Fv/Fm) activities of cells from A measured using a FluorCAM system. Data are mean ± se, n = 4 biological replicates; raw data plots (white circles) are shown.
