| 摘 要： | 非编码RNA参与了多种重要的生命进程,是当今研究的热点领域。在植物中,非编码RNA除了参与维持基因组的稳定,还在生长、发育、逆境胁迫反应等过程中发挥重要作用。RNA干扰(RNA interference,RNAi)是指由RNA触发的相应基因的表达抑制,是非编码RNA调控基因表达的一种重要的作用方式,自发现以来已逐渐发展为遗传分析、疾病治疗以及植物保护等方面的有效的新技术。文章重点介绍了微RNA(micro RNA,mi RNA)在植物抗虫防御中的生物学功能,si RNA对植物防御记忆的影响以及RNAi对植物防御信号途径的调节作用,同时阐述了RNAi在提高农作物抗虫性上的应用并展望了未来植物非编码RNA的研究方向。

| Abstract: | Non-coding RNAs (ncRNAs), including long non-coding RNAs (lncRNAs) and small RNAs such as microRNAs (miRNAs) and short interference RNAs (siRNAs), exist widely in eukaryotes and affect gene expressions at different levels. In plant, ncRNAs are involved in growth, development, response to biotic and abiotic stresses, and are important players in epigenetics. RNA interference (RNAi) refers to homology gene silencing caused by double strand RNAs (dsRNAs) and is a major mechanism of gene expression regulation by ncRNAs. Since discovery, RNAi has been developed as a powerful technology for genetic analysis, gene therapy, and plant protection. In this review, we summarize the recent progresses in research of the function and mechanism of ncRNAs in plant defense pathways and discuss the application of RNAi technology in agricultural pest control. |
