Transcriptomics and metabolomics revealed the molecular basis of the color formation in the roots of <i>Panax notoginseng</i>.

ABSTRACT: Panax notoginseng is a traditional Chinese medicine rich in many pharmacological components. The root of the 'Miaoxiang Sanqi No. 2' is yellow or greenish yellow, while a novel cultivar-'Wenyuan Ziqi No. 1' shows purple root and is thought to have high medicinal value. Little information is available about the anthocyanin biosynthesis in P. notoginseng root. In this study, we compared the 'Miaoxiang Sanqi No. 2' and 'Wenyuan Ziqi No. 1' in morphological, transcriptional and metabolic levels. The results showed that purple rich in the periderm, rhizome and phloem around cambium of the 'Wenyuan Ziqi No. 1' root and cyanidin 3-O-galactoside was the main anthocyanin causing purple. Moreover, 'Wenyuan Ziqi No. 1' highly accumulated in 155 metabolites, including flavones, ph
