Proanthocyanidin pathway gene expression in seed coats of darkening and non-darkening cranberry beans. Transcript levels for each gene are shown for seed coats isolated from seeds of both RILs at early (E), intermediate (I) and mature (M) stages of development, and are expressed as FPKM. Each datum represents the mean ± standard error of three greenhouse replicates. Transcript level data for each gene were analyzed for statistical differences with a one-way analysis of variance; for both RILs and their developmental stages, means were compared with the Tukey’s test. Shared letters indicate no significant differences at p ≤ .05. For each gene transcript, the corresponding gene accession number is provided in brackets: PvPAL2, PHENYLALANINE AMMONIA LYASE 2 (Phvul.001G177700, Phvul.001G177800); PvC4H, CINNAMATE 4-HYDROXYLASE (Phvul.008G247400); Pv4CL1, 4-COUMAROYL:COENZYME A LIGASE 1 (Phvul.002G040100); PvCHS3, CHALCONE SYNTHASE 3 (Phvul.002G038700); PvCHI2, CHALCONE ISOMERASE 2 (Phvul.009G143100); PvF3′H, FLAVONOID 3′-HYDROXYLASE (Phvul.009G192400); PvF3H1, FLAVANONE 3-HYDROXYLASE 1 (Phvul.003G261900); PvDFR1, DIHYDROFLAVONOL 4-REDUCTASE 1 (Phvul.001G012700); PvDFR2, DIHYDROFLAVONOL 4-REDUCTASE 2 (Phvul.001G012800); PvLAR, LEUCOANTHOCYANIDIN REDUCTASE (Phvul.007G102100); PvANS, ANTHOCYANIDIN SYNTHASE (Phvul.002G152700); PvANR1, ANTHOCYANIDIN REDUCTASE 1 (Phvul.002G218700); PvAGT, URIDINE DIPHOSPHATE-GLUCOSE: ANTHOCYANIDIN 3-O-GLUCOSYLTRANSFERASE (Phvul.002G214300); PvMYB6, MYELOBLASTOSIS PROTO-ONCOGENE 6 (Phvul.006G114800); PvMYB9, MYELOBLASTOSIS PROTO-ONCOGENE 9 (Phvul.011G105600); PvMYB11, MYELOBLASTOSIS PROTO-ONCOGENE 11 (Phvul.003G222400); PvMATE1, MULTIDRUG AND TOXIN EXTRUSION 1 (Phvul.008G197000); PvMATE2, MULTIDRUG AND TOXIN EXTRUSION 2 (Phvul.006G028700)
