Relative expression of floral development genes and transcription factors. For the NL and L1 samples, the relative expression of genes and transcription factors involved in the flowering process was determined via quantitative RT-PCR. Expression was normalized to that of UBQ. The transcript levels from the NL sample were set as 1. The blue or red columns represent the expression levels determined by qRT-PCR (left axis), whereas the lines represent the gene expression levels determined by RNA-Seq (right axis). The transcript abundances of the genes encoding a cycling DoF factor 3-like protein, b CONSTANS-LIKE 15, (c) CONSTANS-LIKE 4, d, e circadian clock associated 1, f flowering locus T, g transcription factor TCP4, and h transcription factor TCP15 were determined and compared across the time course of light-induced treatment. Data represent the mean ± SD for three replicates (n = 3). Different lowercase letters above the columns indicate a significant difference at p ≤ 0.05 between the columns according to t tests performed using the SPSS statistical software. Data in columns with the same letters showed no significant difference (p > 0.05)
