The regulation of citric acid metabolism during fruit ripening has a major impact on the production of high-quality fruit. The impact of citric acid on organoleptic fruit quality attributes, fruit storage performance and the synthesis of several secondary metabolites has led to an exponential increase in research efforts during the last two decades. Recent research has focused on the relationship among citric acid biosynthesis, transportation, storage, and utilization. Among citrate metabolic processes, activities of a proton pump, especially the plasma membrane H+-ATPase on tonoplast and citrate catabolism in cytosol play important roles in the regulation of citrate accumulation in cell vacuoles. Moreover, we highlight recent advances and provide an overview of citrate metabolism, postharvest physiology of citrate metabolism, and the influence of agro-climatic factors on citrus fruits. It is the first review that provides a comprehensive model for citrate metabolism in citrus fruit juice sacs. We anticipate that this model for the regulation of citrate metabolism will facilitate the study of fruit acidity in citrus and other nonclimacteric fruits.

柑桔中柠檬酸代谢调控的最新研究进展

水果成熟过程中柠檬酸代谢的调节对高质量水果的生产有重大影响。柠檬酸对感官水果品质属性,水果贮藏性能和几种次生代谢产物的合成的影响导致最近二十年来研究工作呈指数增长。最近的研究集中在柠檬酸生物合成,运输,储存和利用之间的关系。在柠檬酸盐代谢过程中,质子泵的活动,特别是质膜H +-ATPase对液泡液中液泡塑料和柠檬酸盐的分解代谢在调节细胞液泡中柠檬酸盐的积累中起重要作用。此外,我们重点介绍了最新进展,并概述了柠檬酸盐代谢,柠檬酸盐代谢的采后生理以及农业气候因素对柑橘类水果的影响。这是首次为柑橘类果汁囊中的柠檬酸盐代谢提供综合模型的综述。我们预计该柠檬酸盐代谢调控模型将有助于研究柑橘和其他非更年期水果的水果酸度。
