摘要:

植物小RNA (small RNA, sRNA)是植物基因表达调控及基因组稳定性的关键调控因子。根据产生途径及作用方式的不同,其主要分为微小RNA (microRNA,miRNA)和小干扰RNA (small interfering RNA, siRNA)两大类。这些不同类型的sRNA依赖多种加工蛋白产生,也依赖不同效应蛋白帮助其发挥功能,并以不同的方式广泛地参与植物各类发育调控与环境响应的过程。近年来,多物种中的高通量测序数据鉴定到了越来越多新型植物sRNA,sRNA在拟南芥(Arabidopsis thaliana)及各类作物中的研究进展也促进了对其产生方式、调控模式及其生物学功能的深入理解。本文系统综述了不同类型植物sRNA的研究进展,主要包括其生物合成途径、作用机制与生物学功能,并结合现有技术讨论了植物sRNA在农业中的应用方式及其作为新型RNA农药的应用前景,旨在为植物sRNA的深入研究及农业应用提供理论基础。

Abstract:

Plant small RNAs (sRNAs) are essential regulators of gene expression and genome stability in plants. Based on their biogenesis and mechanisms of action, they are primarily classified into two major categories: microRNAs (miRNAs) and small interfering RNAs (siRNAs). These sRNAs rely on distinct processing proteins for their production and effector proteins to execute their functions, playing pivotal roles in diverse developmental processes and environmental responses. Recent advances in next-generation sequencing have identified numerous novel sRNAs across multiple plant species, while studies in Arabidopsis thaliana and various crops have significantly enhanced our understanding of their biogenesis, regulatory networks, and biological functions. In this review, we systematically summarize the research progress on different classes of plant sRNAs, focusing on their biosynthetic pathways, molecular mechanisms, and biological function. Furthermore, we discuss the potential applications of plant sRNAs in agriculture, including their prospects as next-generation RNA pesticides, supported by current technological developments. This review aims to provide a theoretical foundation for further research on plant sRNAs and their agricultural applications.
