摘要：

Ethylene and 1-methylcyclopropene (1-MCP) are the most commonly used postharvest treatments for various fruits in recent years, that can be used to accelerate or delay the ripening of fruit according to demand. However, these treatments may also affect fruit intrinsic nutrients while regulating the ripening process. Here, integrated transcriptomics and metabolomics analyses were performed to comprehensively reveal the effects of ethylene and 1-MCP treatments on kiwifruit quality during ripening. It was found that ethylene treatment mainly upregulated the metabolism of phenolic acids, while 1-MCP treatment mainly down-regulated the content of lipid metabolites. These differential metabolites and genes were mainly enriched in "Plant hormone signal transduction (ko04075)" and "Biosynthesis of secondary metabolites (ko01110)" two KEGG pathways. Moreover, both ethylene and 1-MCP treatments up-regulated the flavonoids content of kiwifruit, which might be achieved by enhancing the expression of two key flavonoid metabolism genes Acc08530 (AcPAL1) and Acc08481 (AcPAL2).
