b1 — Chlorophyll a/b ratio does not differ significantly from that of wildtype.
b1 — In leaves, 30% and 45% decrease in violaxanthine and neoxanthine, respectively, and 18% increase in lutein compared to wildtype. &
b1 — In seeds, lutein content is unchanged; zeaxanthin, violaxanthin and neoxanthin are decreased; antheraxanthin is increased (all relative to wildtype). Increase total level of β-carotene-derived xanthophylls.
b1 — Level of total carotenoid not significantly different from wild-type.
b1 — No visible phenotype.
b1 b2 — In leaves, &
b1 b2 — In seeds, carotenoids levels were reduced to 40% of those of wildtype. &
b1 b2 — Level of total carotenoid not significantly different from wild-type.
b1 b2 — No visible phenotype.
b1 b2 — Non-photochemical quenching (NPQ) reduced to a much greater extent in both induction and amplitude compared to either single mutants.
chy1 chy2 — Reduced conversion of &
chy1 chy2 lut5 — Contains high levels of lutein.
chy1 chy2 lut5 — No trace of β-carotene-derived xanthophylls.
lut1 b1 — In leaves, 25% increase in zeinoxanthin levels; 25% and 35% reduction in violaxanthin and lutein, respectively; %beta;-Carotene increased by 35%; all in relation to single mutant lut1-2.
