Abstract

Terrestrial plants can affect the growth and health of adjacent via interspecific interaction. Here, we studied mechanism by which plant root exudates recruitment rhizosphere microbiome in plants—with implications for protection—using a tomato (Solanum lycopersicum)–potatoonion (Allium cepa var. agrogatum) intercropping system. First, showed that system results disease-suppressive protects against Verticillium wilt disease caused soilborne pathogen Verticillium dahliae. Second, 16S rRNA gene sequencing revealed with potatoonion altered composition promoting colonization specific Bacillus sp. This taxon was isolated shown to inhibit V. dahliae induce systemic resistance plants. Third, belowground segregation experiment found mediated interaction between tomato. Moreover, experiments using split-root from potatoonion, especially taxifolin—a flavonoid compound—stimulate recruit plant-beneficial bacteria, such as Lastly, ultra-high-pressure liquid chromatography–mass spectrometry analysis taxifolin alters exudate chemistry; thus, this compound acts indirectly modulating Our improve fitness changing use signaling chemicals released potatoonion. study novel modulates establishment microbiome, thus opening up new avenues research precision manipulations.

Legume rhizodeposition promotes nitrogen fixation by soil microbiota under crop diversification

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Апрель 4, 2024

Abstract Biological nitrogen fixation by free-living bacteria and rhizobial symbiosis with legumes plays a key role in sustainable crop production. Here, we study how different combinations influence the interaction between peanut plants their rhizosphere microbiota via metabolite deposition functional responses of symbiotic nitrogen-fixing bacteria. Based on long-term (8 year) diversified cropping field experiment, find that co-cultured maize oilseed rape lead to specific changes profiles bacterial functions nodulation. Flavonoids coumarins accumulate due activation phenylpropanoid biosynthesis pathways peanuts. These enhance growth activity isolates, root nodulation Bradyrhizobium isolates. Peanut plant metabolites interact isolates contributing initiate Our findings demonstrate tailored intercropping could be used improve soil availability through microbiome its functions.

The rhizosphere consists of a plethora microbes, interacting with each other as well the plants present in proximity. root exudates consist variety secondary metabolites such strigolactones and phenolic compounds coumarin that helps facilitating communication forming associations beneficial microbes rhizosphere. Among different flavonoids (natural polyphenolic compounds) continuously increasing attention scientific fields for showing several slews biological activities. Flavonoids possess benzo-γ-pyrone skeleton classes have been reported on basis their basic structure flavanones, flavonols, anthocyanins, etc. mutualistic association between plant growth-promoting rhizobacteria (PGPR) to help host surviving various biotic abiotic stresses low nitrogen phosphorus, drought salinity stress, pathogen attack, herbivory. This review sheds light upon one component exudate known flavonoids, which is nodulation legume plants. Apart from well-known role inducing legumes, this group has anti-microbial antifungal properties helping establishing defensive mechanisms playing major mycorrhizal enhanced acquisition nutrients iron phosphorus. Further, highlights recruiting non-mutualistic under stress important aspects regarding recent findings functions metabolite guiding plant-microbe interaction how organic matter affects its functionality soil.

Rational management of the plant microbiome for the Second Green Revolution

Plant Communications, Год журнала: 2024, Номер 5(4), С. 100812 - 100812

Опубликована: Янв. 11, 2024

The Green Revolution of the mid-20th century transformed agriculture worldwide and has resulted in environmental challenges. A new approach, Second Revolution, seeks to enhance agricultural productivity while minimizing negative impacts. Plant microbiomes play critical roles plant growth stress responses, understanding plant-microbiome interactions is essential for developing sustainable practices that meet food security safety challenges, which are among United Nations Sustainable Development Goals. This review provides a comprehensive exploration key deterministic processes crucial microbiome management strategies, including host effect, facilitator microbe-microbe interactions. hierarchical framework modulation proposed bridge gap between basic research applications. emphasizes three levels modulation: single strain, synthetic community, situ modulation. Overall, rational wide-ranging applications can potentially be core technology Revolution.

Beneficial microorganisms: Regulating growth and defense for plant welfare

Plant Biotechnology Journal, Год журнала: 2024, Номер unknown

Опубликована: Дек. 20, 2024

Beneficial microorganisms (BMs) promote plant growth and enhance stress resistance. This review summarizes how BMs induce promotion by improving nutrient uptake, producing growth-promoting hormones stimulating root development. How disease resistance help protect plants from abiotic stresses has also been explored. Growth-defense trade-offs are known to affect the ability of survive under unfavourable conditions. discusses studies demonstrating that regulate growth-defense through microbe-associated molecular patterns multiple pathways, including leucine-rich repeat receptor-like kinase pathway, abscisic acid signalling pathway specific transcriptional factor regulation. multifaceted relationship underscores significance in sustainable agriculture. Finally, need for integration artificial intelligence revolutionize biofertilizer research highlighted. elucidates cutting-edge advancements potential plant-microbe synergistic microbial agents.

Spatial profiling of microbial communities by sequential FISH with error-robust encoding

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Март 17, 2023

Abstract Spatial analysis of microbiomes at single cell resolution with high multiplexity and accuracy has remained challenging. Here we present spatial profiling a microbiome using sequential error-robust fluorescence in situ hybridization (SEER-FISH), highly multiplexed accurate imaging method that allows mapping microbial communities micron-scale. We show RNA can be increased significantly by rounds probe dissociation. Combined error-correction strategies, demonstrate SEER-FISH enables taxonomic identification complex communities. Using composed diverse bacterial taxa isolated from plant rhizospheres, apply to quantify the abundance each taxon map biogeography on roots. At micron-scale, identify clustering cells multiple species rhizoplane. Under treatment metabolites, find re-organization colonization along root alterations association among taxa. Taken together, provides useful for ecology situ.

Abstract The utilization of microbial inoculants in the realm sustainable agricultural and ecosystem restoration has witnessed a surge recent decades. This rise is largely attributed to advancements our understanding plant–microbe interactions, urgency reduce dependence on agrochemicals growing societal demand for strategies management. However, despite rapid growth bio‐inoculants sector, certain limitations persist concerning their efficacy performance under field condition. Here, we propose that seed biopriming, an effective inoculant technique integrating both biological agents (the priming beneficial microbes seeds) physiological aspects (hydration seeds improved metabolically activity), significant potential mitigate these limitations. method increases protection against soil‐borne pathogens soil pollutants, such as salts heavy metals, while promoting germination rate uniformity, leading overall primary productivity health. Furthermore, argue coating can facilitate transgenerational associations microbes, refine plant microbiomes, maintain legacies microflora. review article aims improve biopriming approach potent valuable tool achieving agriculture successful restoration.
