Functional Characterization of Flavanone 3-Hydroxylase (F3H) and Its Role in Anthocyanin and Flavonoid Biosynthesis in Mulberry.

ABSTRACT: Mulberry (Morus spp., Moraceae) is an important economic crop plant and is rich in flavonoids and anthocyanidins in ripe fruits. Anthocyanins are glycosides of anthocyanidins. Flavanone 3-hydroxylase (F3H) catalyzes the conversion of naringenin into dihydroflavonols and is responsible for the biosynthesis of flavonols and anthocyanidins. In this study, MazsF3H was cloned and characterized from Morus atropurpurea var. Zhongshen 1. Conserved motif analysis based on alignment and phylogenetic analysis indicated that MazsF3H belonged to 2-oxoglutarate-dependent dioxygenase and MazsF3H clustered with F3Hs from other plants. MazsF3H was located in both nucleus and cytosol. MazsF3H was expressed in stems, leaves, stigmas and ovaries, except
