Catechins, the most important bioactive components in tea plants (Camellia sinensis), are influenced by growth environment. To identify and optimize key meteorological factors affecting catechin accumulation, we investigated relationship between plant biosynthesis across three growing seasons at 10 locations. Rainfall, average temperature, effective accumulated temperature (EAT) were identified as drivers regulating accumulation via responsive expression of structural genes CsCHS1, CsANR, CsSCPL. Optimal conditions for enhancing total esterified catechins (TEC) non-esterified (TNEC) determined using LINGO software, although optimal these two groups contrasting. Hot rainy environments promote EGCG, ECG, TEC through CsPAL CsSCPL, while reduced rainfall EAT C, EGC, TNEC. This study reveals differential effects on obtains promoting accumulation. These results provide guidance improving cultivation management.
