Molecular developmental basis of the colour polymorphism. a Simplified diagram of the cyanidin branch of the anthocyanin pathway (see Supplementary Fig. 5), showing ANS and its typical regulation by MYB-bHLH-WDR transcription factor complexes. b Concentrations of the two main anthocyanin pigments found in G. rhellicani flowers (ANOVA; see Supplementary Fig. 4, Supplementary Table 6); centre lines denote medians, bounds of boxes denote first and third quartiles, whiskers denote 1.5× interquartile ranges. c Two of the 13 transcripts significantly differentially expressed between black and white plants map to GrANS1 (Supplementary Table 7). d Close-up of a ‘white’ flower; lateral labellum lobes still contain red pigment, suggesting a mutation in a regulator of spatial anthocyanin expression. e Transcriptome-wide association between SNPs and approximate cyanidin content (spectral reflectance): three top-10 SNPs occur in GrMYB1 (Supplementary Table 8)
