Gene variations within putative genes governing anthocyanin leaf markings in A17 and R108. A Differences in the anthocyanin leaf markings between the two ecotypes. B Alignment of the protein sequences of the RH1 and RH2 genes. Blue and orange underlines indicate the R2 repeat domain (R2 domain) and R3 repeat domain (R3 domain), respectively. The green underline indicates the C-terminal domain (CTD). C VISTA sequence conservation plot of the RH1 and RH2 genes obtained by comparing A17 to R108. The gray area indicates a 100 bp deletion located within the first intron of RH2. D Sequence conservation plot of the intergenic regions obtained by comparing the two genes
