摘要: 李属植物果实营养丰富,为人类提供了大量的营养物质,但是其果实采后迅速软化,导致果实品质下降、不耐贮藏及货架期短。为了解李属植物果实成熟软化的研究概况,本研究归纳总结了李属植物果实成熟过程中包括呼吸作用、乙烯释放、品质相关物质变化在内的生理变化,细胞壁结构、物质成分变化、细胞壁降解相关酶在内的细胞壁变化,果实成熟软化相关的基因及果实成熟软化蛋白质组学研究进展,并提出了存在的问题及未来研究趋势。指出目前李属植物果实成熟软化研究集中于果实采收后或贮藏期间细胞壁物质成分、结构变化及细胞壁降解相关酶,如多聚半乳糖醛酸酶、β-半乳糖苷酶等的活性变化,及这些酶的基因克隆、功能分析,指出结合转录组学、蛋白质组学、代谢组学和基因组学等几种组学将是李属植物果实成熟软化研究的发展方向。

Abstract: The fruit of Prunus is rich in minerals, antioxidants, flavonoides and glutathione, which contribute significantly to human nutrition and are considered to be one series of the most important commodities consumed worldwide. The fruit firmness declined rapidly after post-harvest, resulting in the decrease of the fruit quality, bad fruit storability and short of shelf life. Aiming to understand the survey of Prunus fruit ripening and softening, and provide a reference to further research the mechanism of fruit ripening and softening of Prunus plant, this paper summarized the proceeding of the physiological changes including respiration, ethylene production, quality related materials, cell wall changes such as structure, composition and enzymes involved in cell wall degradation, progress of gene related to fruit ripening and softening and proteomics research in fruit ripening and softening. It also pointed out the existing problems and proposed the research directions. The paper believed that the current research of fruit ripening and softening of Prunus were concentrated in the changes of cell wall material composition and structure, enzyme activity changes of cell wall degradation related enzyme such as polygalacturonase and β -galactosidase, and the gene cloning and function analysis of cell wall degradation enzyme. The combination of transcriptomics, proteomics, metabolomics and genomics studies will be the development direction of the Prunus plant fruit ripening and softening research.
