Abstract:

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.
