近年来,我国植物病毒学的研究非常活跃,应用分子生物学技术,单克隆抗体技术来研究植物病毒的组成成分,病毒的结构与功能;病毒抗原型株系的划分和病毒疫苗的研制,迅速地向纵深的领域开拓,大大地促进了植物病毒学与植物病理学的发展,并为农业生产带来了经济效益。现从几个方面来谈我国植物病学研究最新进展。一、植物类病毒的研究植物类病毒是由分子量为100000—120000kd的单股环状RNA所组成,无外层衣壳蛋白。其二级结构是由带有许多单股环构成的一系列双股螺旋构成的。类病毒的复制可借助于宿主的依赖DNA的
In recent years, the research on plant virology in our country is very active. The molecular composition and the structure and function of the plant virus are studied by using molecular biology techniques and monoclonal antibody technology. The division of virus antigenic strains and the development of virus vaccine are rapid To the depth of field development, greatly promoted the development of plant virology and plant pathology, and brought economic benefits for agricultural production. Now from several aspects of China’s latest progress in plant disease research. First, the study of plant-based viruses Plant-based viruses is composed of single-stranded circular RNA molecular weight 100000-120000kd, no outer coat protein. Its secondary structure is made up of a series of double-helical spirals with many single loops. Virus-like replication can rely on the host’s DNA-dependent
