Effects of UV-B in protein synthesis in Arabidopsis wild-type (WT) plants and rpl10 mutants. In vivo labeling is shown for leaf proteins with [³⁵S]Met in control plants (no UV-B) and after exposure under UV-B radiation for 4 h (4 h UV-B; A) and after a period of 16 h of recovery in the absence of UV-B (no UV-B + 16 h recovery) and 4 h of UV-B radiation (4 h UV-B + 16 h recovery; B). Data show averages and sd of the quantification of radioactive bands by densitometry of the autoradiographs. The percentage of labeling was corrected for loading differences per lane in SDS-PAGE. The experiments were repeated three times using four plants in each experiment. For each mutant plant and condition analyzed, different letters over the bars indicate significant differences at P < 0.05.
