Total chlorophyll, chlorophyll a, chlorophyll b, chlorophyll a/b ratio; lutein; de-epoxidation state of xanthophyll cycle carotenoids calculated as (A/2 + Z)/(Z + A + V); (Z, zeaxanthin; V, violaxanthin; A, antheraxanthin), and β-carotene. Values are means (±SD) of 9−12 plants per genotype from at least two independent experiments (n = 9–12) expressed as the peak area per µg of dry weight. Asterisks indicate significant differences from the wild type according to the Tukey HSD test at the level of p < 0.05 (*), p < 0.005 (**), or p < 0.001 (***).
