Taming of the microbial beasts: Plant immunity tethers potentially pathogenic microbiota members.

Plants are in intimate association with taxonomically structured microbial communities called the plant microbiota. There is growing evidence that the plant microbiota contributes to the holistic performance and general health of plants, especially under unfavorable situations. Despite the attached benefits, surprisingly, the plant microbiota in nature also includes potentially pathogenic strains, signifying that the plant hosts have tight control over these microbes. Despite the conceivable role of plant immunity in regulating its microbiota, we lack a complete understanding of its role in governing the assembly, maintenance, and function of the plant microbiota. Here, we highlight the recent progress on the mechanistic relevance of host immunity in orchestrating plant-microbiota dialogues and discuss the pluses and perils of these microbial assemblies.
