Response of photosynthetic capacity to ecological factors and its relationship with EGCG biosynthesis of tea plant (Camellia sinensis).

ABSTRACT:

Background

Epigallocatechin gallate (EGCG) imparts unique health benefits and flavour to tea. Photosynthesis plays a crucial role in modulating secondary metabolite production in plants, and this study investigated its impact on the biosynthesis of EGCG in tea plants under different ecological conditions.

Results

Enhanced photosynthetic activity and the increased EGCG content, total esterified catechins (TEC), total catechins (TC) responded synchronously to changes in ecological factors. The photosynthetic capacity of tea plants and the EGCG content fit surface model equations (Extreme 2D and Polynomial 2D) and multiple regression equations (R² > 70%). Additionally, logistic regression and ROC curves revealed that photosynthetic capacity was related to EGCG accumu
