Characterization of Two Key Flavonoid 3-O-Glycosyltransferases Involved in the Formation of Flower Color in Rhododendron Delavayi.

ABSTRACT: Flower color, largely determined by anthocyanin, is one of the most important ornamental values of Rhododendron delavayi. However, scant information of anthocyanin biosynthesis has been reported in R. delavayi. We found that anthocyanidin 3-O-glycosides were the predominant anthocyanins detected in R. delavayi flowers accounting for 93.68-96.31% of the total anthocyanins during its development, which indicated the key role of flavonoid 3-O-glycosyltransferase (3GT) on R. delavayi flower color formation. Subsequently, based on correlation analysis between anthocyanins accumulation and Rd3GTs expressions during flower development, Rd3GT1 and Rd3GT6 were preliminarily identified as the pivotal 3GT genes involved in the form
