Functional Characterization of F3H Gene and Optimization of Dihydrokaempferol Biosynthesis in .

The 1092 bp F3H gene from Roxb., which was named TbF3H, was cloned and it encodes 363 amino acids. Bioinformatic and phylogenetic tree analyses revealed the high homology of TbF3H with flavanone 3-hydroxylase from other plants.
