Identifying meteorological factors influencing catechin biosynthesis and optimizing cultivation conditions of tea plant (<i>Camellia sinensis</i>).

ABSTRACT: Catechins, the most important bioactive components in tea plants (Camellia sinensis), are influenced by the growth environment. To identify and optimize the key meteorological factors affecting catechin accumulation, we investigated the relationship between meteorological factors and tea plant catechin biosynthesis across three growing seasons at 10 locations. Rainfall, average temperature, and effective accumulated temperature (EAT) were identified as key drivers regulating catechin accumulation via the responsive expression of key structural genes CsCHS1, CsANR, and CsSCPL. Optimal meteorological conditions for enhancing total esterified catechins (TEC) and total non-esterified catechins (TNEC) were determined using LINGO software, although the optimal conditi
