摘　　要：植物线虫是世界农业上危害最严重且最难防治的病原物之一,可以寄生多种植物,每年造成数十亿美元损失。生防菌可以激发植物的一些抗病基因表达,从而激活某些免疫途径,对植物线虫的侵染、发育产生抑制作用。这种特性使植物-生防菌-线虫三者构成全新的生物调控关系,成为植物免疫研究的新模型。非编码RNA是生物学领域热点研究内容,其可能参与了植物线虫和其他生物如生防微生物等调控植物免疫的反应。本文综述了miRNA、lncRNA和circRNA等在微生物、植物线虫与寄主互作过程中研究现状;阐述了miRNA作为新兴的基因表达转录后调节因子在影响植物发育、调控植物免疫反应上的作用;进一步介绍了假单胞菌诱导植物体内的miRNA和lncRNA产生变化,从而使这些非编码RNA参与到生防菌激活植物免疫反应的过程;最后展望了生防菌调控植物免疫抵抗线虫侵染研究发展方向。Plant nematodes are one of the most harmful and difficult pathogens in world agriculture.They can parasitize many plant species and cause billions of dollars of loss in each year.Biocontrol bacteria may activate the expressions of some disease-resistant genes,thus activate the some immune pathways,therefore inhibiting the infection,growth and development of plant nematodes.This characteristic makes the plant,biocontrol bacteria and nematodes constitute a new bio-regulatory relationship and it becomes a new model of plant immunity research.Non-coding RNA is a hot research topic in the field of biology,and it may be involved in the regulation of plant immunity by plant nematodes and other organisms such as biocontrol microorganisms.In this paper,the roles of miRNA,lncRNA and circRNA in the interactions among microorganisms,plant nematodes and their hosts are reviewed.miRNA,as an emerging post-transcriptional regulator of gene expression,largely affects the development of plants and regulates their immune responses.Pseudomonas can induce changes in miRNA and lncRNA in plants,and then these non-coding RNAs may participate in the process of biocontrol bacteria activating plant immunity.Finally,the future research direction of molecular mechanism of biocontrol bacteria regulating plant immunity against nematodes infection is prospected.
