The Dominant late2-1D Mutant Shows Reduced Responsiveness to Photoperiod.
(A) Comparison of late2-1D with photoperiod response mutants phyA-1 and late1-2 and their wild-type progenitor line NGB5839 (WT) grown under LD conditions.
(B) Effect of photoperiod on flowering and other traits in wild-type (NGB5839) and late2-1D plants. Values represent mean ± se for n = 6 to 8 replicates.
(C) Distribution of flowering time in F2 progeny of the cross NGB5839 (WT) × late2-1D. The distribution in an F2 progeny of the cross wild type × late1-2 is shown for comparison.
(D) Genetic interaction of late2-1D with phyA-1 and late1-2 in control of flower initiation and growth termination under LD conditions. Values represent mean ± se for n = 6 to 8 replicates.
