Black mung bean is rich in anthocyanin, however, the accumulation and the molecular mechanism of anthocyanin synthesis in black mung bean are unclear. In this study, anthocyanin metabolomics and transcriptomics on the seed coats of two different colors of mung bean were performed to clarify the composition of anthocyanins, and identify transcription factors involved in regulating anthocyanin biosynthesis. In the mature stage, 23 kinds of anthocyanin compounds were identified. All anthocyanin components contents were significantly higher in seed coat of black mung bean compare with green mung bean. Transcriptome analysis suggested that most of the structural genes for anthocyanin biosynthesis and some potential regulatory genes were significantly differentially expressed. WGCNA suggested VrMYB90 was an important regulatory gene in anthocyanin biosynthesis. Arabidopsis thaliana overexpressing VrMYB90 showed significant accumulation of anthocyanins. PAL, 4CL, DFR, F3'5'H, LDOX, F3'H and UFGT were up-regulated in 35S:VrMYB90 Arabidopsis thaliana. These findings provide valuable information for understanding the synthesis mechanism of anthocyanins in black mung bean seed coats
