The Roles of MicroRNAs in the Regulation of Rice–Pathogen Interactions

Rice is exposed to attacks by the three most destructive pathogens, <i>Magnaporthe oryzae</i> (<i>M. oryzae</i>), <i>Xanthomonas oryzae</i> pv. <i>oryzae</i> (<i>Xoo</i>), and <i>Rhizoctonia solani</i> (<i>R. solani</i&...

description Rice is exposed to attacks by the three most destructive pathogens, <i>Magnaporthe oryzae</i> (<i>M. oryzae</i>), <i>Xanthomonas oryzae</i> pv. <i>oryzae</i> (<i>Xoo</i>), and <i>Rhizoctonia solani</i> (<i>R. solani</i>), which cause substantial yield losses and severely threaten food security. To cope with pathogenic infections, rice has evolved diverse molecular mechanisms to respond to a wide range of pathogens. Among these strategies, plant microRNAs (miRNAs), endogenous single-stranded short non-coding RNA molecules, have emerged as promising candidates in coordinating plant–pathogen interactions. MiRNAs can modulate target gene expression at the post-transcriptional level through mRNA cleavage and/or translational inhibition. In rare instances, they also influence gene expression at the transcriptional level through DNA methylation. In recent years, substantial advancements have been achieved in the investigation of microRNA-mediated molecular mechanisms in rice immunity. Therefore, we attempt to summarize the current advances of immune signaling mechanisms in rice–pathogen interactions that are regulated by osa-miRNAs, including their functions and molecular mechanisms. We also focus on recent findings concerning the role of osa-miRNAs that respond to <i>M. oryzae</i>, <i>Xoo</i>, and <i>R. solani</i>, respectively. These insights enhance our understanding of how the mechanisms of osa-miRNAs mediate rice immunity and may facilitate the development of improved strategies for breeding pathogen-resistant rice varieties.
