摘要： The UGT72 gene family encodes proteins that glycosylate phenylpropanoids, and thus contribute to the synthesis of various phenolic substances. However, their functional role and evolutionary history in Pyrus spp. remains poorly understood. Here we explored the evolution, amplification, coding region structural variation, and functional divergence of the UGT72 gene family and its subfamilies. Further, we identified functional genes involved in arbutin synthesis and functionally validated the key genes. 15 UGT72 genes were identified in the complete genome sequence and classified into two subfamilies of Pyrus betulifolia. Significant expansion of the UGT72 gene family occurred after genome duplication in P. betulifolia. 53.33 % of all UGT72 family genes were found to have undergone expansion via WGD/segmental duplication. A noteworthy discovery was that the amplification of functional genes such as PbUGT72B1714 during polyploidization, combined with the loss of vital motifs and variations at important sites within these genes, significantly impacted the diversification of arbutin metabolism. These findings offer novel insights into how gene gains and losses caused by WGDs have contributed to metabolic diversification and evolutionary adaptation in Pyrus, as well as a groundwork for more detailed investigations into the mechanisms of arbutin metabolism.
