Figure 2

Expression pattern, phylogenetic reconstruction, and LOGO analysis of AmCYP76AD1. (a) The leaf color phenotypes and betalain absorbance spectra of the upper and lower leaves of the red-leaf cultivar (AMR) of four-week-old A. tricolor. (b) Expression levels of core betalain biosynthesis genes in the upper and lower leaves of four-week-old AMR plants analyzed by qRT-PCR. Statistically significant differences were determined using Student’s t-test (*P < 0.01 for the upper leaves of AMR vs. the lower leaves of AMR). (c) Phylogenetic tree of CYP76AD homologues. The species, families, and accession numbers of CYP76AD homologues are available in Supplementary Table S6. (d) Proportional LOGO plots of selected amino acids identified by Brockington et al9 were generated based on the CYP76ADα and CYP76ADβ homologues listed in (c). Positions are numbered according to the residues of AmCYP76AD1 and AmCYP76AD6.
