谷氨酰胺合成酶（GS）在茶树芽（最年轻的最顶叶）中的表达量和活性最高，在老叶中的表达量和活性较低，而在茎和根中的活性最低。GS的表达和活性增加铵和硝酸盐，镉和盐胁迫，但铜，铝，干旱，冷，热胁迫降低。
Glutamine synthetase (GS) showed highest expression and activity in bud (youngest topmost leaf) ofCamellia sinensis, lower in older leaves, while lowest activity in stem and roots. GS expression and activity was increased by ammonium and nitrate and also by cadmium and salt stress but decreased by copper, aluminum, drought, cold and heat stress.
