摘　　要：[Objective]The aim was to explore the molecular mechanism of plant resistance to various stress response.[Method]The expression of LeWRKY1 in tomato seedlings under treatment with B.cinerea,exogenous JA and SA were explored by real time quantitative RT-PCR technology.[Result]JA induced the expression of LeWRKY1,but SA did not.LeWRKY1 expression was up-regulated under B.cinerea infection.[Conclusion]LeWRKY1 might be involved in the tomato defense response to B.cinerea through JA dependent but SA independent signal pathway.[目的]为了研究LeWRKY1参与植物抗逆反应的分子机理。[方法]采用实时荧光定量PCR技术研究了LeWRKY1在番茄灰霉菌(Botrytis cinerea)侵染、茉莉酸(jasmonic acid,JA)、水杨酸(salicylic acid,SA)刺激时的表达情况。[结果]外源植物激素JA可诱导LeWRKY1的表达,而SA对其无明显诱导作用;番茄灰霉菌侵染可诱导LeWRKY1表达。[结论]LeWRKY1可能通过JA依赖而SA非依赖的信号途径参与番茄对番茄灰霉菌防御反应的应答。
