Citric acid is one of the important organic acids in the Horticultural crop fruit. Citric acid significantly affects the taste and flavor of the fruit. This paper reviews the status and function of citric acid synthesis,transport,storage and utilization in the accumulation of fruit. This paper emphasized the influences of the proton transfer of proton pump in the tonoplast and the regulation of citric acid accumulation. In addition,it gives an overview to the status of transcription factors,environmental and climatic factors,cultivation management measures and postharvest treatments in the metabolism and accumulation of citric acid. Based on the comprehensive understanding of the metabolic mechanism of citric acid synthesis and accumulation,the accumulation of citric acid in the fruit can be finely regulated by gene editing,to obtain the fruit with more suitable sugar-to-acid ratio and better taste.

Key words: citric acid, transport protein, metabolism, fruit acidity
