摘要(Abstract)：

【目的】研究枇杷果实成熟过程中不同发育阶段(青果期、转色期和成熟期)的生理代谢变化及果实品质形成机制。【方法】以‘解放钟’枇杷品种为试验材料,采用蛋白质双向凝胶电泳及MALDI-TOF/TOF-MS技术分离并鉴定蛋白质,采用RT-qPCR技术分析基因表达水平变化,同时应用生理生化技术分析生理代谢变化。【结果】成功鉴定出55个差异表达蛋白,这些蛋白主要参与糖代谢(16%)、三羧酸循环与能量代谢(9%)、抗坏血酸-谷胱甘肽循环(14%)、类胡萝卜素合成及乙烯合成(11%)、蛋白质合成(13%)、细胞结构(8%)、防御与胁迫(9%)以及其它调控(13%)等生物学过程。随着果实成熟,参与糖代谢、三羧酸循环与能量代谢以及类胡萝卜素合成及乙烯合成过程的相关蛋白均上调表达;RT-qPCR的结果与蛋白质丰度变化趋势相一致;同时,糖类物质、类胡萝卜素以及维生素C等的含量不断积累,有机酸含量不断减少。【结论】在蛋白质丰度、生理生化水平以及mRNA水平上的结果共同表明糖代谢、三羧酸循环及能量代谢、类胡萝卜素合成以及乙烯合成等代谢途径在枇杷果实品质形成过程中起着重要作用。这些结果为枇杷果实品质改良提供重要的理论依据,并为今后枇杷新品种的培育奠定分子生物学基础。
