摘要： UDP-glycosyltransferase (UGT) is essential for fruit development, but its specific role in sweet cherry fruits has not been clearly defined. This study identified a new differentially expressed UGT gene, FUN_010048, by analyzing transcriptomic data from various colored regions of bicolored fruits. The 187 UGT family members were identified in the sweet cherry genome of 'Tieton'. Notably, FUN_010084 has been renamed PavUGT48. Expression analysis revealed that PavUGT48 increased during the development of the differently colored sweet cherry fruits. Co-expression network analysis and further experiments confirmed that PavUGT48 generates cyanidin-3-O-glucoside from cyanidin using UDP-glucose (UDP-Glc) as the sugar donor, enhancing fruit coloration. Additionally, PavUGT48 facilitates the formation of amygdalin from prunasin, but it does not react with naringenin, dihydrokaempferol, or kaempferol when UDP-Glc serves as the sugar donor. These findings enhance our understanding of UGT enzymes in sweet cherries and provide a basis for improving fruit quality and developing new varieties.
