主 题：1-Methylcyclopropene apple fruit quality metabolomics transcriptomics
摘 要：In this study,integrative metabolomics and transcriptomics analyses were conducted to investigate the effects of 1-methylcyclopropene(1-MCP)on apple fruit quality during long-term cold *** results showed that 1-MCP(1μL/L)treatment could maintain fruits apparent quality(*** color and firmness),inhibit the increase of rot rate and soluble solids content/titratable acidity ratio,decrease ethylene release,and respiratory intensity during cold storage,and extend shelf ***,1-MCP had long-term effects on the accumulation of many qualities related to metabolite and gene expression in fruits.1-MCP affected genes related to metabolism at the early stage of storage,specifically those of the glycolysis and tricarboxylic acid cycle *** related to the degradation of sucrose,starch,and cellulose were inhibited,and some starch and cellulose synthesis genes were up-regulated by *** from ethylene synthesis and signal transduction being inhibited by 1-MCP,several enzymes(pectinesterase,pectate lyase,polygalacturonase)were involved in pectin degradation,and degradation products of the cell wall(i.e.D-galacturonic acid and D-glucuronic acid)were also strongly inhibited,further maintaining fruit ***,as precursor glutathione(GSH)related to plant resistance,up-regulated the synthase ***,the expression of genes related to cyanoalanine syn-thase and amino acid utilization pathways was suppressed by 1-MCP Collectively,1-MCP could maintain the postharvest quality of apple fruits.
