Glycosylation is a common modification of plant proteins,hormones and other substances,and plays an important role in maintaining the normal growth and development of plants.Glycosylation in plants is catalyzed by glycosyltransferases.The full-length sequence of MsUGT73 B2 gene was cloned by RACE-PCR using reference sequence of Medicago truncatula,and its amino acid sequence,secondary structure,and physicochemical properties were analyzed by bioinformatics.The gene expression was analyzed by qRT-PCR.By cons...
