摘　　要：蔗糖酶在植物体内催化蔗糖水解为葡萄糖和果糖,为植物的生长和发育提供碳源和能源,是植物体内碳水化合物代谢中的关键酶。蔗糖酶参与植物细胞的生长和发育、信号传导及对机械损伤、病菌侵害等各种胁迫的响应等方面发挥重要的作用。Sucrase catalyzes the irreversible hydrolysis of sucrose into glucose and fructose,the mainforms of carbon and energy supplies in plant growth and development.In plants,due to the central role of Sucrase in assimilate transport,which is considered as a key enzyme for carbohydrate metabolism.Moreover,Sucrase also plays important functions in controlling of cell growth and development,signal transduction,and plant response to wounding、infection and kinds of stress.

关 键 词：蔗糖酶 关键酶 信号传导
