qPCR relative expression of CYC-like paralogs for external and internal florets. a Relative expression pattern for external petal types by paralog. b Relative expression pattern for internal petal types by paralog. c Relative expression pattern for dorsal petals. d Relative expression pattern for ventral petals (note difference in y axis values). Abbreviations for petal types are as follows: D dorsal petals, LL left lateral petals, RL right lateral petals, and V ventral petals. Standard error bars are shown. Statistical significance among petal types is as follows: *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001
