摘　　要：为了得到抗病毒的寄主植物,植物育种学家进行了许多有益研究,形成了许多行之有效的抗病毒病育种策略。利用植物本身对病毒侵染所具有的一些免疫功能及其本身的一些抗性基因来获得抗性;利用来源于病毒自身基因的一些抗病性策略(PDR),如利用病毒外壳蛋白基因,病毒复制酶基因,病毒移动蛋白基因,病毒卫星RNA和反义RNA等,植物也可以获得抗性。近年来对由转录后RNA沉默引起的由RNA介导的病毒抗性策略(RMVR)也进行了深入地研究。除了PDR和RMVR以外,还有一些导致植物抗病毒的策略,包括利用美国商陆的病毒抗性蛋白(PAP),2',5'-寡腺苷酸合成酶,"植物抗体"以及病毒蛋白多肽来获得病毒抗性等。To obtain virus-resistant host plants, many studies have been done by plant breeders, and a range of operational strategies were found now. Plants obtain resistance by using natural immune hypersensitivity and dominant resistance genes. The resistance might be obtained by plant pathogen-derived resistance (PDR) strategies, such as the use of the virus coat protein genes, virus replicase genes, virus movement protein genes, virus satellite RNA and antisense RNA. The phenomenon of post-translational RNA silencing to mediate virus resistance (RMVR) have been wildly studied for virus resistance as well. In addition to using of R-genes, PDR and RMVR, other strategies, including the use of pokeweed antiviral protein (PAP), 2', 5'-oligoadenylate synthetase, 'plantibodies' and peptide, were applied in some case.
