Effects of the Loss of Function of AGL16 on Flowering Time Depend on the Photoperiod.

RLNs at flowering are shown for each line grown under LD (A), SD (B), and equal light-night (MD; [C]) conditions. Below the graph, the genotypes of each bar are marked for the three genes: AGL16, FRI, and FLC, with a plus sign indicating wild type or functional allele and a minus sign indicating loss of function. The mean values of RLN for each line together with the sd are shown. Statistical analyses were performed with two-tailed Student’s t test with Bonferroni correction (shown here) and confirmed with a Wilcoxon test. ***P < 0.001, **P < 0.01, and *P < 0.05. Note that in the flc-3 background, the absence of AGL16 can accelerate the flowering time under both MD (C) and SD (B) conditions.
