Zusammenfassung:Organic acid content is one of the most important factors influencing fruit flavors. The predominant organic acid in most pear cultivars is malic acid, but the mechanism controlling its accumulation remains unclear. In this study, by comparing gene expression levels and organic acid contents, we found that the expression of PbPH5, which encodes a P3A-ATPase, is highly correlated with malic acid accumulation in four different pear species, with correlation coefficients of 0.932**, 0.656*, 0.900**, and 0.518* (*, P
