Alignment and the phylogeny of African violet SiCYC1A and SiCYC1B with selected Gesneriaceae GCYC homologs. (A) The alignment of SiCYC1A and SiCYC1B with AmCYC (snapdragon), with TCP, ECE, and R domains is indicated. (B) The ML tree with AmCYC as outgroup. The topology indicates that the evolution of Gesneriaceae GCYC homologs contains multiple duplication events (arrow heads). In particular, the duplication before the divergence of genus Streptocarpus (including African violet) which gave rise to GCYC1A (SiCYC1A) and GCYC1B (SiCYC1B) becomes the major paralogs involving floral symmetry transitions in African violet. ML bootstrap supports (> 70%) and BI posterior probabilities (> 0.80) are labeled.
