Fig. 2From: Slow darkening of pinto bean seed coat is associated with significant metabolite and transcript differences related to proanthocyanidin biosynthesisProposed proanthocyanidin biosynthetic pathway in pinto bean seed coats. The multiple arrows indicate multiple steps and dashed arrows indicate speculative steps. The ovals indicate membrane transporters. PAL, phenylalanine ammonia lyase; C4H, cinnamate-4-hydrolase; 4CL, 4-coumarate-CoA ligase; CHS, chalcone synthase; CHR, chalcone reductase; CHI, chalcone isomerase; F3H, flavanone 3-hydroxylase; F3’H, flavonoid 3′-hydroxylase; F3’5’H, flavonoid 3′,5′-hydroxylase; DFR, dihydroflavonol reductase; ANS, anthocyanidin synthase; FLS, flavonol synthase; LAR, leucoanthocyanidin reductase; ANR, anthocyanidin reductase; ANS, anthocyanidin synthase; MATE, multidrug and toxic compound extrusion proteinBack to article page
