The pigment composition of the vtc2-1 and vtc2-4 leaves compared with the wild type (WT). Plants were grown under low light (LL; 250 μmol m-2 s-1) conditions for 5 weeks and then either for a further 7 d under LL conditions or after transfer to high light (HL; 1600 μmol m–2 s–1) growth conditions for 7 d. Leaves were harvested from plants grown only under LL, after 7 d growth under HL, and after ‘recovery’ (2 d after return to the LL growth environment after 7 d under HL). De-epoxidation state (DEPs)=(Z+0.5A)/(V+A+Z); XC: xanthophyll pool (Z+A+V)/(Z+A+V+N+L+β-car) where Z, zeaxanthin; V, violaxanthin; A, antheraxanthin; N, neoxanthin; L, lutein; β-car, β-carotene. Data are presented as means ± SEM from five replicates. * indicates significantly different results during each experimental time point according to ANOVA, P<0.05.
