Expression profiles of genes involved in flower development. (A) Expression profiles of genes involved in flower development obtained by the DEGseq analysis of the 454 transcripts. The colors indicate the expression values scaled to the standard deviations and are centered at the control intensity level (Z-score). Red indicates increased expression and green indicates decreased expression relative to the control condition. Gene expression at time points labeled with an asterisk on the map showed differential expression between the treated and control inflorescence meristems (p <0.05), whereas the remaining genes were considered to not respond to BA treatment (p >0.05). (B) Quantification of gene expression by qRT-PCR. Results are shown as the relative expression of genes at different time points before and after BA treatment. Values are means ± standard deviations (n =3). **Statistically significant at the 1% level.
