Carotenoid content and NPQ in the isolated gox mutants. Non-photochemical quenching of chlorophyll fluorescence (NPQ) (A), carotenoid contents (B-C), and α-tocopherol content (D) of 20 gox mutants were analyzed in cultures grown either under LL (15 μmol photons m-2 s-1) or HL conditions (250 μmol photons m-2 s-1). The order of clones is the same as in Table 1, divided into HL sensitive and t-BOOH resistant mutants (n.d.: not determined). Data show averages from 4-5 independent experiments (± SE), and significant (P < 0.05) differences from wild-type are indicated by a star (in B significance of deepoxidation of xanthophylls ([Z+A]/[Z+A+V]) is shown).
