The entire evolutionary trajectory of plants towards large and complex multi-cellular organisms has been accompanied by incessant interactions with omnipresent unicellular microbes. This led to the evolution highly microbial communities, whose members display spectrum pathogenic mutualistic behaviors. Plant roots are dynamic, fractally growing organs even small Arabidopsis harbor millions individual microbes diverse taxa. It is evident that at different positions on a root surface could experience fundamentally environments, which, moreover, rapidly change over time. Differences in spatial scales between compares humans cities they inhabit. Such considerations make it mechanisms root-microbe can only be understood if analyzed relevant temporal scales. review attempts provide an overview rapid recent progress made mapping manipulating plant damage immune responses cellular resolution, as well visualizing bacterial communities their transcriptional activities. We further discuss impact such approaches will have for more predictive understanding interactions.

Plants grown in natural soil are colonized by phylogenetically structured communities of microbes known as the microbiota. Individual can activate microbe-associated molecular pattern (MAMP)-triggered immunity (MTI), which limits pathogen proliferation but curtails plant growth, a phenomenon growth-defence trade-off. Here, we report that, monoassociations, 41% (62 out 151) taxonomically diverse root bacterial commensals suppress Arabidopsis thaliana growth inhibition (RGI) triggered immune-stimulating MAMPs or damage-associated patterns. Amplicon sequencing 16S rRNA genes reveals that immune activation alters profile synthetic (SynComs) comprising RGI-non-suppressive strains, whereas presence RGI-suppressive strains attenuates this effect. Root colonization SynComs with different complexities and activities expression 174 core host genes, functions related to development nutrient transport. Furthermore, specifically downregulate subset immune-related genes. Precolonization plants SynComs, mutation one commensal-downregulated transcription factor, MYB15, renders more susceptible opportunistic Pseudomonas pathogens. Our results suggest modulate susceptibility pathogens either eliciting dampening MTI responses, respectively. This interplay buffers system against perturbation defence-associated inhibition, ultimately leading commensal-host homeostasis.

Abstract The phytohormones salicylic acid (SA) and jasmonic (JA) are major players in plant immunity. Numerous studies have provided evidence that SA- JA-mediated signaling interact with each other (SA-JA crosstalk) to orchestrate immune responses against pathogens. At the same time, SA-JA crosstalk is often exploited by pathogens promote their virulence. In this review, we summarize our current knowledge of molecular mechanisms for modulations during pathogen infection.

Modern agriculture faces several challenges due to climate change, limited resources, and land degradation. Plant-associated soil microbes harbor beneficial plant growth-promoting (PGP) traits that can be used address some of these challenges. These are often formulated as inoculants for many crops. However, inconsistent productivity a problem since the performance individual inoculants/microbes vary with environmental conditions. Over past decade, ability utilize Next Generation Sequencing (NGS) approaches has led an explosion information regarding associated microbiomes. Although this type work been predominantly sequence-based descriptive in nature, increasingly it is moving towards microbiome functionality. The synthetic microbial communities (SynCom) approach emerging technique involves co-culturing multiple taxa under well-defined conditions mimic structure function microbiome. SynCom hopes increase community stability through synergistic interactions between its members. This review will focus on plant-soil-microbiome how they have potential improve crop production. Current formulation discussed, practical application considered.

Plants interact with a diversity of microorganisms that influence their growth and resilience, they can therefore be considered as ecological entities, namely "plant holobionts," rather than singular organisms. In plant holobiont, the assembly above- belowground microbiota is ruled by host, microbial, environmental factors. Upon microorganism perception, plants activate immune signaling resulting in secretion factors modulate composition. Additionally, metabolic interdependencies antagonism between microbes are driving forces for community assemblies. We argue complex plant-microbe intermicrobial interactions have been selected during evolution may promote survival fitness associated holobionts. As part this process, evolved metabolite-mediated strategies to selectively recruit beneficial microbiota. Some these members show host-adaptation, from which mutualism rapidly arise. also co-evolved antagonistic activities restrict proliferation high pathogenic potential prevent disease development. Co-evolution within holobionts thus ultimately drives performance.
