Integrative Metabolome and Transcriptome Analyses Reveal the Effects of Plucking Flower on Polysaccharide Accumulation in the Rhizomes of <i>Polygonatum cyrtonema</i> Hua.

ABSTRACT: Polysaccharides are the major bioactive components of Polygonatum cyrtonema Hua, and their biosynthesis and accumulation are influenced by many agronomic practices. In this study, we applied integrative metabolome and transcriptome analyses to investigate the accumulation of bioactive components in one-year-old (1Y) and six-year-old (6Y) rhizomes of P. cyrtonema Hua treated with a plucking flower. The compound content analysis suggested that six-year-old treated rhizomes (T6) accumulated the highest polysaccharide content compared to that of one-year-old treated rhizomes (T1), one-year-old untreated rhizomes (C1), and six-year-old untreated rhizomes (C6). Metabolomics analysis showed that 4-O-galactopyranosylxylose, 6-O-α-l-arabinopyranosyl-d-glucopyranose, d-ar
