The MP fragments were then fused with constitutive expression promoter CaMV 355 and pathogen - inducible promoters CHS, Pill and BG, respectively, which led to the consmiction of plant expression vectors p355-30K, pPiII-30K, pPiII-30K and pBG-30K.

• MP片段分别与组成型启动子CaMV35S和病原特异诱导型启动子CHS、PiII和BG体外重组，构建成植物表达载体P35S－30K，pCHS－30K，pPiII－30K和pBG－30K。 通过农杆菌LBA4404介导，分别转化含Tin－22抗性基因的番茄品种Geneva80。
