Virus-inoculation results in Tm -22 transgenic tobacco showed the expression of Tm -22 gene was single-copy integration and inherence, in which encoded protein displayed resistant to isolate TMV, ToMV-0, ToMV-2 and susceptible to ToMV-2a.

• 转Tm-22基因烟草接种的结果表明,Tm22基因在烟草上的表达为单基因整合和遗传,其编码蛋白对TMV、ToMV-0和ToMV-2三个毒株的分离物表现抗性和对ToMV-2a毒株的分离物表现感病,与Tm-22番茄对ToMV病毒不同株系的特异反应结果一致;
