Real-time PCR identification of selected candidate genes related to anthocyanin biosynthesis. There were seven candidate genes including five transcription factors which might regulate anthocyanin, BIM2, MYB21, bHLH30, ARALYDRAFT (ARRI) and bHLH49; and E3 ubiquitin-protein ligase and Alpha-xylosidase. Significant differences of Xianghongtai01 compared withYinong50D are indicated by * based on the Students t test, (*P < 0.05, ** P < 0.01; ***P < 0.001). The transcript levels of the genes are normalized to actin transcript level and expressed relative to PPIS which is set to 1. In all cases means ± SD (n = 3) are represented
