摘要： Starch degradation with fruit ripening is closely related to the aging process and flavor formation in apples. In this study, ethylene, 1-methylcyclopropene (1-MCP), and apples treated at different temperatures were used to determine the key genes of starch-sugar metabolism during storage. Compared with 4 degrees C storage, 20 degrees C storage promoted starch degradation and sugar accumulation in apples. In addition, ethylene treatment promoted starch degradation and sugar accumulation in apples, while 1-MCP treatment showed the opposite effects. The expression of MdBams indicated the crucial role of MdBam5 in starch-sugar conversion. Transient overexpression of MdBam5 significantly reduced the starch content in apples. Furthermore, MdWRKY32 directly combined the MdBam5 promoter and activated the MdBam5 expression, which may promote the starch degradation in apples. Therefore, it was concluded that MdWRKY32 may be involved in the regulation of starch-sugar metabolism in postharvest apples by activating the MdBam5 expression.
