摘　　要：[目的]探究新合成化合物——茉莉酸甲酯(MeJA)类似物B2对烟草花叶病毒侵染(TMV)烟草的抑制效果及机理。[方法]B2处理烟草叶片后,接种烟草花叶病毒,并测定了TMV在烟草叶片中的含量,超氧化物歧化酶(SOD)活性和脂氧酶(LOX)活性,调控茉莉酸信号途径的NtRab11基因、茉莉酸信号通路中的关键基因COI 1、植物抗病基因介导的系统抗性中的标志基因PR-1a和PR-1b的相对表达量。[结果]B2处理后,与对照相比,烟草叶片中的TMV含量有所下降,SOD和LOX活性提高,tRab11、COI1、PR-1a和PR-1b的相对表达量都有提高。[结论]新合成化合物B2对TMV侵染烟草有一定的抑制效果。[Objective]To explore inhibitory effect and mechanism of a newly synthesized compound methyl jasmonate analogue B2 on tobacco infected by tobacco mosaic virus(TMV).[Method]After treated with B2,tobacco leaves were inoculated by TMV,then TMV content in tobacco,SOD and LOX activity,and the relative expression levels of NtRab11,COI1,PR-1a and PR-1b were measured.[Result]Compared to controls,TMV content in tobacco leaves was decreased,SOD and LOX activity were increased,and relative expression levels of NtRab11,COI1,PR-1a and PR-1b were increased after treated with B2.[Conclusion]A newly synthesized compound B2 has certain inhibitory effect on TMV infection of tobacco.
