Relations between LHCII/PSII (A) and PSI/PSII (B) ratios and the relative content of xanthophylls on thylakoids. Parameters were measured for wild-type and 11 xanthophyll biosynthesis mutants plants previously described (; present ms). LHCII/PSII and PSI/PSII ratios were determined on thylakoid membranes by quantitative western blot, while xanthophyll/carotenoid ratios were quantified by HPLC. Both distributions were fitted with exponential functions (y = yo + a·ebx); RLHCII/PSII2 = 0.76; RPSI/PSII2 = 0.78.
