a Principal component analysis (PCA) of metabolites in seed coats. Different colored dots represent the ZY821 (black), RNAi-1 (RNAi-BnA09myb47a-1, yellow), and RNAi-2 (RNAi-BnA09myb47a-2, blue). Different shapes represent the developmental stages of the seed coat. b KEGG pathways associated with the biosynthesis of differential metabolites in the seed coat. P values by one-tailed hypergeometric test with false discovery rate. c Heatmap representing the relative contents of compounds (nmol/g FW) in GH06 and ZY821 (as controls) and transgenic (overexpression [OE] and RNAi) samples, with the ratio expressed in log2 scale. RNAi-47, RNAi-BnA09myb47a, and OE-47, BnA09MYB47a-overexpression. Contents of soluble (d) and insoluble (e) proanthocyanidins (PAs) in the seed coats of ZY821, GH06, OE-BnA09MYB47a and RNAi-BnA09myb47a transgenic lines. P values were calculated using multiple t tests without adjustments, compared to levels in ZY821. Values represent the average ± SEM of three biological replicates.
