Metabolic and transcriptome analysis of dark red taproot in radish (Raphanus sativus L.).

ABSTRACT: The red color in radish taproots is an important quality index and is mainly affected by anthocyanins. However, the metabolite components and gene expression underlying dark red taproot color formation in radish remain elusive. In this study, the metabolites and gene expression patterns affecting anthocyanin biosynthesis were monitored in the dark red taproots. Comparative analysis of anthocyanin metabolites between dark red taproots and white taproots indicated that pelargonin and pelargonidin 3-O-beta-D-glucoside were the most promising dark red pigments responsible for the coloration of the taproots. Transcriptomic analysis of gene expression between dark red taproots and white taproots revealed that most of genes involved in the anthocyanin biosynthesis pathway were up-regulated in dar
