Plant roots communicate with microbes in a sophisticated manner through chemical communication within the rhizosphere, thereby leading to biofilm formation of beneficial and, case plant growth-promoting rhizomicrobes / -bacteria (PGPR), resulting priming defense or induced resistance host. The knowledge plant-plant and plant-microbe interactions have been greatly extended over recent years; however, is far from being well understood. Furthermore, linkage between below- above-ground physiological processes adds complexity. In metabolomics studies, main aim profile annotate all exo- endo-metabolites biological system that drive participate processes.

Summary Plants solely rely on innate immunity of each individual cell to deal with a diversity microbes in the environment. Extracellular recognition microbe‐ and host damage‐associated molecular patterns leads first layer inducible defenses, termed pattern‐triggered ( PTI ). In plants, pattern receptors PRR s) described date are all membrane‐associated receptor‐like kinases or proteins, reflecting prevalence apoplastic colonization plant‐infecting microbes.

Systems Biology of Plant-Microbiome Interactions

Molecular Plant, Journal Year: 2019, Volume and Issue: 12(6), P. 804 - 821

Published: May 23, 2019

In natural environments, plants are exposed to diverse microbiota that they interact with in complex ways. While plant–pathogen interactions have been intensely studied understand defense mechanisms plants, many microbes and microbial communities can substantial beneficial effects on their plant host. Such include improved acquisition of nutrients, accelerated growth, resilience against pathogens, resistance abiotic stress conditions such as heat, drought, salinity. However, the bacterial strains or consortia host often cultivar species specific, posing an obstacle general application. Remarkably, signals trigger immune responses molecularly highly similar identical pathogenic microbes. Thus, it is unclear what determines outcome a particular microbe–host interaction which factors enable distinguish beneficials from pathogens. To unravel network genetic, microbial, metabolic interactions, including signaling events mediating comprehensive quantitative systems biology approaches will be needed.

Plant immunity in signal integration between biotic and abiotic stress responses

New Phytologist, Journal Year: 2019, Volume and Issue: 225(1), P. 87 - 104

Published: June 18, 2019

Plants constantly monitor and cope with the fluctuating environment while hosting a diversity of plant-inhabiting microbes. The mode outcome plant-microbe interactions, including plant disease epidemics, are dynamically profoundly influenced by abiotic factors, such as light, temperature, water nutrients. also utilize associations beneficial microbes during adaptation to adverse conditions. Elucidation molecular bases for plant-microbe-environment interactions is therefore fundamental importance in sciences. Following advances into individual stress signaling pathways, recent studies beginning reveal intersections between biotic responses regulatory principles combined responses. We outline mechanisms underlying environmental modulation immunity emerging roles immune regulators tolerance. Furthermore, we discuss how plants coordinate conflicting demands when exposed combinations different stresses, attention possible determinant that links initial response broad-spectrum tolerance or prioritization specific

Summary Climate change is increasing global temperatures and the frequency severity of droughts in many regions. These anthropogenic stresses pose a significant threat to plant performance crop production. The plant‐associated microbiome modulates impacts biotic abiotic on fitness. However, climate change‐induced alteration composition activities microbiomes can affect host functions. Here, we highlight recent advancements our understanding impact (warming drought) plant–microbiome interactions their ecological functions from genome ecosystem scales. We identify knowledge gaps, propose new concepts make recommendations for future research directions. It proposed that short term (years decades), adaptation plants mainly driven by microbiome, whereas long (century millennia), will be equally eco‐evolutionary between its host.

In nature, plants must respond to multiple stresses simultaneously, which likely demands cross-talk between stress-response pathways minimize fitness costs. Here we provide genetic evidence that biotic and abiotic stress responses are differentially prioritized in Arabidopsis thaliana leaves of different ages maintain growth reproduction under combined stresses. Abiotic stresses, such as high salinity drought, blunted immune older rosette through the phytohormone abscisic acid signaling, whereas this antagonistic effect was blocked younger by PBS3 , a signaling component defense salicylic acid. Plants lacking exhibited enhanced tolerance at cost decreased Together with role, is also indispensable for establishment salt stress- leaf age-dependent phyllosphere bacterial communities. Collectively, our work reveals mechanism balances trade-offs upon conflicting organism level identifies intersection among plant immunity, microbiota, tolerance.
