Transcript levels of flowering time genes in WT, phyB-null and phyC-null mutants under SD conditions assayed by qRT-PCR. Each data point represents the mean of four biological replications and error bars represent SEM. Different letters denote significant differences between samples at the 0.05 confidence level and only significant differences are presented. All primers used to assay expression were redundant for A and B homeologs, except for FT-A3 and FT-B3. The WT control headed at 14 w, and at 17 w plants showed signs of senescence so were not sampled
