摘要

RNA 沉默（或 RNA 干扰，RNAi）是真核生物中一种保守的基因表达调控机制，在植物生长发育以及应对生物和非生物胁迫方面发挥着重要作用。跨域 RNAi 和种间 RNAi 的发现为利用基于 RNAi 的作物保护策略提供了理论基础。在此，我们总结了植物中的典型 RNAi 机制，并回顾了与植物病原体相互作用相关的代表性研究。同时，我们还阐述了宿主诱导基因沉默、喷雾诱导基因沉默和微生物诱导基因沉默的原理，并讨论了它们在作物保护中的应用，从而为建立基于 RNAi 的新型作物保护策略提供帮助。

Advances in the mechanisms and applications of RNA silencing in crop protection.

RNA silencing (or RNA interference, RNAi) is a conserved mechanism for regulating gene expression in eukaryotes, which plays vital roles in plant development and response to biotic and abiotic stresses. The discovery of trans-kingdom RNAi and interspecies RNAi provides a theoretical basis for exploiting RNAi-based crop protection strategies. Here, we summarize the canonical RNAi mechanisms in plants and review representative studies associated with plant-pathogen interactions. Meanwhile, we also elaborate upon the principles of host-induced gene silencing, spray-induced gene silencing and microbe-induced gene silencing, and discuss their applications in crop protection, thereby providing help to establish novel RNAi-based crop protection strategies.
