DEGs related to anthocyanin biosynthesis in immature diploid embryos derived from B73×CAU5 under dark and light conditions. A Simplified map of the anthocyanin biosynthesis pathway. Red indicates up-regulated genes and green indicates down-regulated genes. MBW represents the MYB-bHLH-WD transcription factor complex. B Expression profile of genes related to anthocyanin biosynthesis in immature diploid embryos. The color indicates the FPKM value of the genes (high: red, low: blue). C Relative expression levels of 14 genes associated with the anthocyanin biosynthetic pathway obtained through qRT-PCR. Data represent the mean ± standard deviation; ns, not significant, ** represents p-value < 0.01 and *** represents p-value < 0.001 for the comparison of values between dark and light conditions (two-tailed t test)
