qRT-PCR of flower-bud late genes in peach cultivars. The expression of genes from cluster A (A), cluster B (B) and non-clustered genes (C) was measured by qRT-PCR in the RNA samples employed in the microarray hybridization experiment shown in Figure 2. Expression levels are relative to actin. The mean value of expression in ‘Red Candem’ was set to one, and the rest of the values were shown relative to ‘Red Candem’. Data are means from two biological replicates, with error bars representing ± SD.
