Metabolomics and microbial community analysis provides new insights into tea quality in different oolong tea cultivars.

ABSTRACT: Oolong tea originates from Fujian Province, and stands out for its characteristic flavor. Tea leaves microbiota and metabolites are increasingly recognized for regulating tea quality, however, the mechanism by which microorganism affect metabolites, and relationship between microorganism and metabolites remain unclear. In this study, microbiomes, metabolites and their correlation were investigated. The results showed that fungal microbiome structure changed more significantly than the bacterial one. Proteobacteria, bacteroidota, Actinobacteriota and Ascomycota were most dominant phylum, there were different key biomarker genera among different tea cultivars. Among 2017 metabolites identified in tea leaves, differential metabolites were enriched in phenylpropanoid biosynthesis
