Abstract

Gene silencing guided by small RNAs governs a broad range of cellular processes in eukaryotes. Small RNAs are important components of plant immunity because they contribute to pathogen-triggered transcription reprogramming and directly target pathogen RNAs. Recent research suggests that silencing of pathogen genes by plant small RNAs occurs not only during viral infection but also in nonviral pathogens through a process termed host-induced gene silencing, which involves trans-species small RNA trafficking. Similarly, small RNAs are also produced by eukaryotic pathogens and regulate virulence. This review summarizes the small RNA pathways in both plants and filamentous pathogens, including fungi and oomycetes, and discusses their role in host-pathogen interactions. We highlight secondarysmall interfering RNAs of plants as regulators of immune receptor gene expression and executors of host-induced gene silencing in invading pathogens. The current status and prospects of trans-species gene silencing at the host-pathogen interface are discussed.

小rna在植物免疫和丝状病原体毒力中的作用。

在真核生物中，由小rna引导的基因沉默控制着广泛的细胞过程。小rna是植物免疫的重要组成部分，因为它们有助于病原体触发的转录重编程，并直接靶向病原体rna。最近的研究表明，植物小RNA对病原体基因的沉默不仅发生在病毒感染过程中，也发生在非病毒病原体中，这一过程被称为宿主诱导的基因沉默，涉及到跨物种的小RNA运输。同样，真核病原体也会产生小rna并调节毒力。本文综述了植物和丝状病原体(包括真菌和卵菌)中的小RNA途径，并讨论了它们在宿主-病原体相互作用中的作用。我们强调了植物的次级小干扰rna在入侵病原体中作为免疫受体基因表达的调节剂和宿主诱导的基因沉默的执行者。综述了宿主-病原体界面基因沉默的研究现状和前景。
