Expression patterns of structural DEGs related to anthocyanin biosynthesis in F. nilgerrensis and its interspecific hybrids. The level of gene expression was measured in F. nilgerrensis Schlecht. (FN) and its interspecific hybrids BF1 and BF2. Red indicatesa high level of expression at different samples. The the red dashed box represents the downstream metabolites of BZ1 gene. The abbreviations of each gene that encodes enzymes and compounds are provided in abbreviations. The levels of gene expression in these biosynthetic pathways are shown in Table S3
