Abstract:

Flavanone 3-hydroxylase(F3H),as a central enzyme for plants to enter the branch of different flavonoid metabolites,can generate dihydroflavonol,a common precursor substance for the synthesis of anthocyanins and flavonols,and it plays a very important regulatory role in the synthesis of flavonoids. From the discovery,structure,function,and expression regulation of the F3H gene,this article reviews the research progress and regulation network of F3H gene in regulating the synthesis of anthocyanins and flavonols,and prospects the future direction. It is aimed to provide a reference for understanding the regulation mechanism of F3H gene on the metabolic synthesis pathway of plant flavonoids,and also help researchers to use F3H with genetic engineering method to obtain the new plant germplasm via directive breeding.

Key words: F3H, flavonoids, anthocyanin, metabolic regulation
