Rhizosphere Microbiome Cooperations: Strategies for Sustainable Crop Production

An understanding of the complexities of microbial interactions and factors affecting their assembly in the community is necessary to benefit maximally from the cooperations of various microbial communities for sustainable crop production.

Rhizosphere Signaling: Insights into Plant–Rhizomicrobiome Interactions for Sustainable Agronomy

Rhizospheric plant–microbe interactions have dynamic importance in sustainable agriculture systems that have a reduced reliance on agrochemicals. Rhizosphere signaling focuses on the interactions

Recent advances in the role of plant metabolites in shaping the root microbiome

The evidence for several plant metabolites affecting plant interaction with microbes belowground and the development of new approaches to study the mechanisms of such interaction that will help to elucidate the metabolic networks in the rhizosphere are reviewed.

Modulation of the Root Microbiome by Plant Molecules: The Basis for Targeted Disease Suppression and Plant Growth Promotion

Understanding how plants manipulate their microbiome can aid in the design of next-generation microbial inoculants for targeted disease suppression and enhanced plant growth.

Rhizospheric plant-microbe interactions: microRNAs, a key mediator

: 12 The importance of microorganisms in plant development, nutrition and stress resistance 13 is consensus and has led to a more holistic approach of plant-microbe interactions, 14 under the

The rhizosphere microbiome: Plant–microbial interactions for resource acquisition

Current knowledge and perspectives on plant–microbial interactions for resource acquisition are summarized and promising advances for manipulating rhizosphere microbiomes and root exudation are discussed.



The Plant Microbiota: Systems-Level Insights and Perspectives.

This work highlights major recent findings in plant microbiota research using comparative community profiling and omics analyses, and discusses these approaches in light of community establishment and beneficial traits like nutrient acquisition and plant health.

Root microbiota drive direct integration of phosphate stress and immunity

It is established that a genetic network controlling the phosphate stress response influences the structure of the root microbiome community, even under non-stress phosphate conditions, and that the master transcriptional regulators of phosphate Stress Response in Arabidopsis thaliana directly repress defence, consistent with plant prioritization of nutritional stress over defence.

Structure, variation, and assembly of the root-associated microbiomes of rice

Dynamic changes observed during microbiome acquisition, as well as steady-state compositions of spatial compartments, support a multistep model for root microbiome assembly from soil wherein the rhizoplane plays a selective gating role.

Rhizosphere microbiome assemblage is affected by plant development

It is surmised that plants secrete blends of compounds and specific phytochemicals in the root exudates that are differentially produced at distinct stages of development to help orchestrate rhizosphere microbiome assemblage.

Signaling in the Rhizosphere.

Defining the core Arabidopsis thaliana root microbiome

The pyrosequencing of the bacterial 16S ribosomal RNA gene of more than 600 Arabidopsis thaliana plants is reported to test the hypotheses that the root rhizosphere and endophytic compartment microbiota of plants grown under controlled conditions in natural soils are sufficiently dependent on the host to remain consistent across different soil types and developmental stages.

Revealing structure and assembly cues for Arabidopsis root-inhabiting bacterial microbiota

Methodology is described to characterize and compare soil- and root-inhabiting bacterial communities, which reveals not only a function for metabolically active plant cells but also for inert cell-wall features in the selection of soil bacteria for host colonization.

Root microbiome relates to plant host evolution in maize and other Poaceae.

It is shown that the genetic distance between rhizobacterial communities correlated significantly with the phylogenetic distance (derived from chloroplastic sequences) between Poaceae genotypes, indicating that eukaryotic host's evolutionary history can be a significant factor shaping directly the assembly and composition of its associated bacterial compartment.

Structure and functions of the bacterial microbiota of plants.

The plant microbiota emerges as a fundamental trait that includes mutualism enabled through diverse biochemical mechanisms, as revealed by studies on plant growth- Promoting and plant health-promoting bacteria.
