AI Article Synopsis
- Plant immune receptors detect harmful microbes and trigger biochemical responses to fend off most threats, while their role against beneficial microbes (commensals) is less understood.
- Recent studies show that commensal microbes can also avoid or attenuate plant immune defenses.
- The plant immune system not only influences the composition of the microbiome but also helps maintain microbial balance and enhances overall plant defense against pathogens.
Article Abstract
Plant immune receptors perceive microbial molecules and initiate an array of biochemical responses that are effective against most invaders. The role of the plant immune system in detecting and controlling pathogenic microorganism has been well described. In contrast, much less is known about plant immunity in the context of the wealth of commensals that inhabit plants. Recent research indicates that, just like pathogens, commensals in the plant microbiome can suppress or evade host immune responses. Moreover, the plant immune system has an active role in microbiome assembly and controls microbial homeostasis in response to environmental variation. We propose that the plant immune system shapes the microbiome, and that the microbiome expands plant immunity and acts as an additional layer of defense against pathogenic organisms.
