The results of RT-qPCR of SaCYC1, SaCYC2, SaCYC3A and SaCYC3B on dorsal, lateral and ventral petal at St1 to St2 in S. aemula. Only SaCYC2 was expressed specifically in the dorsal region. Error bars of gene expression are ± 1 SD from three biological replicates. Different letters indicate statistically significant differences at p <0.05 according to Tukey’s HSD test.
