Proposed model of the proanthocyanidin biosynthesis pathway in cranberry bean seed coats. The proposed biosynthetic genes are based on information that is available for Arabidopsis and M. truncatula [17, 20, 22,22,24]. Structures corresponding to underlined anthocyanins, flavan-3-ols, and proanthocyanidins are based on HPLC-MS metabolite data described by Chen et al. [5, 41]. Gene abbreviations include: ANR, ANTHOCYANIDIN REDUCTASE; ANS, ANTHOCYANIDIN SYNTHASE; AGT, URIDINE DIPHOSPHATE-GLUCOSE: ANTHOCYANIDIN 3-O-GLUCOSYLTRANSFERASE; CHS, CHALCONE SYNTHASE; CHI, CHALCONE ISOMERASE; C4H, CINNAMATE 4-HYDROXYLASE; 4CL, 4-COUMAROYL:COENZYME A LIGASE; DFR, DIHYDROFLAVONOL 4-REDUCTASE; F3′H, FLAVONOID 3′-HYDROXYLASE; F3H, FLAVANONE 3-HYDROXYLASE; LAR, LEUCOANTHOCYANIDIN REDUCTASE; PAL, PHENYLALANINE AMMONIA LYASE
