Analysis of the epoxidation state in Lhca-deficient antisense plants

Time after High-Light Treatment	0 Min	5 Min	60 Min
WT	0.99	0.89	0.55
-a2	0.99	0.93	0.61
-a3	0.97	0.89	0.55

Dark-adapted wild-type (WT) and Lhca2 (-a2) and Lhca3 (-a3) antisense plants were illuminated with a PPFD of 700 μmol m⁻² s⁻¹. Leaves were taken from four plants, pooled, and frozen in liquid nitrogen 0, 5, and 60 min after high-light treatment. The pigment content was analyzed by HPLC and epoxidation state was calculated as (V ⁺ A/2)/(V ⁺ A ⁺ Z), where A, V, and Z denote concentrations of antheraxanthin, violaxanthin, and zeaxanthin, respectively.
