摘要： This study aimed to elucidate the effect of cutting on the quality of melon fruit (cv. Xizhoumi-17) during storage as we l l as assess changes at metabolite level by an LC-MS-based comparative metabolomics profiling and multivariate analysis. A total of 93 differential metabolites were observed in whole and fresh-cut melon during storage. Among them, 10 differential metabolites were found exclusively in stored whole melon, and 17 non-repetitive differential metabolites were found during storage of fresh-cut melon compared to stored whole melon. 4' -Methyl-(-)-epigallocatechin 3' -glucuronide (MEG) and pyranocyanin A of flavonoids accumulated in melon fruit during storage; in fresh-cut melon, increased flavonoid biosynthesis induced by the higher expression of CmPAL1-9, CmC4H1-4, and Cm4CH1/2/3 might explain accumulation of MEG and pyranocyanin A. Moreover, ce l l membrane composition in melon changed throughout storage, as indicated by the increased contents of phosphatidic acids (PAs), phospholipid inositols (PIs), phosphatidylglycerols (PGs), and monogalactosyldiacyl-glycerols (MGDGs) as wel l as the decreased contents of Lyso PG, Lyso PIs, Lyso PCs, Lyso PEs, and Lyso PAs. Cutting of melon promoted change in cel l membrane composition, resulting from the increased expression of CmPLC1/2/3, CmPLD1/2/3, CmAGPAT, and CmGPAT1/2 in fresh-cut me l o n compared to whole melon. In addition, increased content of salicylic acid beta-D-glucoside (SAG) was observed in fresh-cut melon during storage compared to the whole melon, indicating that SAG helps the fresh-cut melon in resisting the cut-wounding stress. Therefore, metabolomics might provide a molecular basis for assessing the qualitative deteri-oration of whole and fresh-cut melon during storage.
