Combined metabolome and transcriptome analyses reveal the flavonoids changes and biosynthesis mechanisms in different organs of Hibiseu manihot L.

In order to systematically study the types, distribution and dynamic changes of flavonoids in different tissues of Hibiseu manihot L. (JHK). In present study, metabolomics combined with transcriptome analysis were performed in different tissues (flowers, leaves, stems, roots and seeds) of JHK. The distribution and content ratio of flavonoids in different tissue of JHK were systematically studied and compared, and the mechanism of flavonoid synthesis and related key genes were also identified. This study will pave the way for the research on the active constituents and pharmacology of JHK, and provide the basis and reference for the further study on the mechanism of flavonoids synthesis.
