Linking plant functional genes to rhizosphere microbes: a review

Plant Biotechnology Journal, Journal Year: 2022, Volume and Issue: 21(5), P. 902 - 917

Published: Oct. 22, 2022

The importance of rhizomicrobiome in plant development, nutrition acquisition and stress tolerance is unquestionable. Relevant genes corresponding to the above functions also regulate construction. Deciphering molecular regulatory network plant-microbe interactions could substantially contribute improving crop yield quality. Here, gene-related nutrient uptake, biotic abiotic resistance, which may influence composition function microbial communities, are discussed this review. In turn, microbes on expression functional genes, thereby growth immunity, reviewed. Moreover, we have specifically paid attention techniques methods used link rhizomicrobiome. Finally, propose further explore mechanisms signalling pathways microbe-host gene interactions, potentially be for managing health agricultural systems.

RIN enhances plant disease resistance via root exudate-mediated assembly of disease-suppressive rhizosphere microbiota

Molecular Plant, Journal Year: 2023, Volume and Issue: 16(9), P. 1379 - 1395

Published: Aug. 10, 2023

The RIPENING-INHIBITOR (RIN) transcriptional factor is a key regulator governing fruit ripening. While RIN also affects other physiological processes, its potential roles in triggering interactions with the rhizosphere microbiome and plant health are unknown. Here we show that microbiome-mediated disease resistance via root exudation, leading to recruitment of microbiota suppress soil-borne, phytopathogenic Ralstonia solanacearum bacterium. Compared wild-type (WT) plant, mutants had different exudate profiles, which were associated distinct changes composition diversity. Specifically, relative abundances antibiosis-associated genes pathogen-suppressing Actinobacteria (Streptomyces) clearly lower rin mutants. composition, diversity, suppressiveness microbiomes could be restored by application 3-hydroxyflavone riboflavin, exuded much concentrations mutant. Interestingly, RIN-mediated effects on exudates, Actinobacteria, suppression evident from seedling stage, indicating plays dual role early assembly disease-suppressive late development. Collectively, our work suggests that, while complex trait driven between microbiome, pathogen, it can indirectly manipulated using "prebiotic" compounds promote microbiota.

The microbiota populating the plant–soil continuum defines an untapped resource for sustainable crop production. host plant is a driver taxonomic composition and function of these microbial communities. In this review, we illustrate how genetic determinants have been shaped by domestication diversification. We discuss heritable component recruitment may represent, at least partially, selection functions underpinning growth, development, health their plants magnitude heritability influenced environment. host–microbiota interactions can be treated as external quantitative trait review recent studies associating genetics with microbiota-based traits. also explore results reductionist approaches, including synthetic communities, to establish causal relationships between phenotypes. Lastly, propose strategies integrate manipulation into programs.

A fundamental goal in plant microbiome research is to determine the relative impacts of host and environmental effects on root microbiota composition, particularly how genotype bacterial community composition. Most studies characterizing effect undersample genetic diversity grow plants outside their native ranges, making associations between microbes difficult interpret. Here, we characterized a large panel switchgrass, North American C4 bioenergy crop, three field locations spanning its range. Our data, composed 1,961 samples, suggest that location primary determinant composition; however, substantial heritable variation widespread across taxa, especially those Sphingomonadaceae family. Despite diverse compositions, relatively few highly prevalent taxa make up majority switchgrass microbiota, fraction which shared sites. Local genotypes preferentially recruit/filter for local microbes, supporting idea affinity microbiota. Using genome-wide association, identified loci impacting abundance >400 microbial strains found an enrichment genes involved immune responses, signaling pathways, secondary metabolism. We associated with over half core (i.e., >80% samples), regardless location. Finally, show relationship basal immunity pathway abundances This study brings us closer harnessing manipulating beneficial via genetics.

The genotype of barley cultivars influences multiple aspects of their associated microbiota via differential root exudate secretion

PLoS Biology, Journal Year: 2024, Volume and Issue: 22(4), P. e3002232 - e3002232

Published: April 25, 2024

Plant-associated microbes play vital roles in promoting plant growth and health, with plants secreting root exudates into the rhizosphere to attract beneficial microbes. Exudate composition defines nature of microbial recruitment, different species attracting distinct microbiota enable optimal adaptation soil environment. To more closely examine relationship between genotype we analysed microbiomes landrace (Chevallier) modern (NFC Tipple) barley ( Hordeum vulgare ) cultivars. Distinct differences were observed plant-associated 2 cultivars, plant-growth rhizobacterial genus Pseudomonas substantially abundant Tipple rhizosphere. Striking also phenotypes recruited populations, alongside genotypic clustering by cultivar. Cultivar-driven selection was driven exudate composition, greater abundance hexose sugars secreted from roots better adapted on these metabolites vice versa. operates at molecular level, both gene expression ecologically relevant loci differing Chevallier isolates. Finally, cultivar-driven is important for cultivars showing a preference selected their genetic siblings transplantation assays.
