摘要
病毒作为一种依赖于宿主细胞代谢的病原体对全球农业造成了重大经济损失。虽然目前已利用多种防治策略来控制病毒病,例如培育抗病毒品种、使用化学杀菌剂、切断病毒的感染途径、组织脱毒、传统农业防治等,但都无法从根本上控制病毒病的危害。近年来的研究表明,基因工程手段能够有效对抗植物病毒病害。本文综述了基因工程手段改造植物抗病毒能力的技术和方法。
Plant virus is one of the most economical devastating microorganisms for global agriculture. Although several strategies are useful for controlling viral infection, such as resistant breeds cultivation, chemical bactericides treatment, blocking the infection source, tissue detoxification and field sanitation, viral disease is still a problem in agricultural production. Genetic engineering approach offers various options for introducing virus resistance into crop plants. This paper reviews the current strategies of developing virus resistant transgenic plants.
