Key Points

High sucrose decomposition activity leads to increased fructose and glucose in tea leaves.
Notably, CsSUS3 is essential for sucrose metabolism in the post-harvest phase.
The genomic analysis identified the sucrose synthase gene family in Camellia sinensis.
These findings provide insights for improving tea processing techniques.

Implication

Observational analysis shows CsSUS3 regulates sucrose metabolism in tea leaves, suggesting potential for post-harvest processing.

Abstract

CsSUS3 was involved in sucrose metabolism during withering and mainly endows SUS with decomposition activity, to decompose sucrose and further generate hexose (fructose and glucose). Our results will help to further revealing the function of CsSUSs in sucrose metabolism of tea plant and provide theoretical reference for tea postharvest processing.
