Plant diseases caused by a variety of pathogens can have severe effects on crop plants and even plants in natural ecosystems. Despite many effective conventional approaches to control plant diseases, new, efficacious, environmentally sound and cost-effective approaches are needed, particularly with our increasing human population and the effects on crop production and plant health caused by climate change. RNA interference (RNAi) is a gene regulation and antiviral response mechanism in eukaryotes; transgenic and non transgenic plant-based RNAi approaches have shown great effectiveness and potential to target specific plant pathogens and help control plant diseases, especially when no alternatives are available. Here we discuss ways in which RNAi has been used against different plant pathogens, and some new potential applications for plant disease control.

用于植物病害控制的 RNA 干扰方法。

由多种病原体引起的植物病害会对农作物甚至自然生态系统中的植物产生严重影响。尽管有许多有效的传统方法来控制植物病害，但仍需要新的、有效的、无害环境的和具有成本效益的方法，特别是随着我们不断增加的人口以及气候变化对作物生产和植物健康的影响。RNA干扰（RNAi）是真核生物中的一种基因调控和抗病毒反应机制；转基因和非转基因基于植物的 RNAi 方法已显示出针对特定植物病原体和帮助控制植物病害的巨大有效性和潜力，尤其是在没有替代品的情况下。在这里，我们讨论了 RNAi 用于对抗不同植物病原体的方法，
