AaF3'5'H from Actinidia arguta encodes a 447–amino-acid cytoplasmic protein and is linked to higher flavonoid levels, with overexpression boosting hairy-root flavonoid content.
- Why it matters: The gene’s functional contribution to flavonoid production in Actinidia arguta is unclear, limiting targeted improvement of its bioactive compound profile.
- What they did: The AaF3'5'H coding sequence (1344 bp) was cloned; its effects were tested by overexpressing or VIGS-silencing the gene in Actinidia arguta, including transgenic hairy roots and targeted metabolomics.
- The result: AaF3'5'H overexpression in transgenic hairy roots enhanced root morphogenesis and increased total flavonoids; metabolomics identified 50 differentially expressed metabolites enriched in flavonoid and phenylpropanoid biosynthesis pathways.
