摘要: Hawthorns are important medicinal and edible plants with a long history of health protection in China. Besides cultivated hawthorn, other wild hawthorns may also have excellent medicinal and edible value, such as Crataegus chungtienensis, an endemic species distributed in the Southwest of China. In this study, by integrating the flavor-related metabolome and transcriptome data of the ripening fruit of C. chungtienensis, we have developed an understanding of the formation of hawthorn fruit quality. The results show that a total of 849 metabolites were detected in the young and mature fruit of C. chungtienensis, of which flavonoids were the most detected metabolites. Among the differentially accumulated metabolites, stachyose, maltotetraose and cis-aconitic acid were significantly increased during fruit ripening, and these may be important metabolites affecting fruit flavor change. Moreover, several flavonoids and terpenoids were reduced after fruit ripening compared with young fruit. Therefore, using the unripe fruit of C. chungtienensis may allow us to obtain more medicinal active ingredients such as flavonoids and terpenoids. Furthermore, we screened out some differentially expressed genes (DEGs) related to fruit quality formation, which had important relationships with differentially accumulated sugars, acids, flavonoids and terpenoids. Our study provides new insights into flavor formation in wild hawthorn during fruit development and ripening, and at the same time this study lays the foundation for the improvement of hawthorn fruit flavor.
