采用 PAS- EL ISA法就转非病原病毒 (樱桃卷叶病毒 )基因烟草对同源病毒的抗性进行了研究。试验结果表明 ,染病烟叶冰冻后对 PAS- EL ISA检测结果无影响。人工接种试验结果显示 ,转基因烟草发病率较未转基因烟草低。 PAS- EL ISA检测表明转基因烟草对该种病毒的侵染有一定的抑制作用
The PAS-EL ISA method was used to study the resistance of the non-pathogenic virus (cherry leafroll virus) to homologous viruses. The test results show that infected tobacco leaves frozen PAS-EL ISA test results no effect. The results of artificial inoculation showed that the incidence of transgenic tobacco was lower than that of non-transgenic tobacco. PAS-EL ISA detection showed that the transgenic tobacco had some inhibition on the virus infection
