RNA interference is a known phenomenon of plant immune responses, involving the regulation of gene expression. The key components triggering the silencing of targeted sequences are double-stranded RNA molecules. The regulation of host-pathogen interactions is controlled by miRNA molecules, which regulate the expression of host resistance genes or the genes of the pathogen. The review focused on basic principles of RNA interference as a gene-silencing-based defense mechanism and the role of miRNA molecules in insect genomes. RNA interference as a tool for plant protection management is discussed. The review summarizes current miRNA-based biotechnology approaches for plant protection management.
RNA干扰是植物免疫反应中一种已知的现象，涉及基因表达的调控。触发靶向序列沉默的关键成分是双链RNA分子。宿主与病原体相互作用的调控由miRNA分子控制，这些分子调控宿主抗性基因或病原体基因的表达。本综述聚焦于RNA干扰作为一种基于基因沉默的防御机制的基本原理以及miRNA分子在昆虫基因组中的作用。文中还讨论了RNA干扰作为植物保护管理工具的相关内容。本综述总结了当前基于miRNA的植物保护管理生物技术方法。
