摘要： UDP-glycosyltransferases (UGTs) are widely involved in plant growth and stress responses. However, UGT family are not well understood in cassava. Here, we identified 121 MeUGT genes and classified them into 14 subfamilies by phylogenetic analysis. All MeUGT proteins have typical feature of the UGTs family. Tandem duplications are the crucial driving force for the expansion of MeUGT family. Cis-Acting elements analysis uncovered those 14 kinds of cis-elements associated with biotic and abiotic stress responses. Transcriptomic and qRT-PCR analyses indicated that MeUGT genes participate in postharvest physiological deterioration of storage root and the responses of biotic and abiotic stresses. Of which, MeUGT-14/41 were significantly induced after Xam treatment. Silencing of MeUGT-14 or MeUGT-41 reduced cassava resistance to Xam, verifying the accuracy of transcriptomic data for function prediction. Together, this study characterized the MeUGTs family and revealed their potential functions, which build a solid foundation for MeUGTs associated genetic improvement of cassava.
