Summary The interaction of plants with complex microbial communities is the result co‐evolution over millions years and contributed to plant transition adaptation land. ability be an essential part highly dynamic ecosystems dependent on their diverse communities. Plant microbiota can support, even enable, functions are crucial in sustaining fitness under often rapidly changing environments. composition diversity differs between soil compartments. It indicates that these compartments not static but adjusted by environment as well inter‐microbial plant–microbe communication. Hormones take a role contributing assembly microbiomes, microbes employ same hormones completely different intentions. Here, function go‐betweens influence shape discussed. versatility microbe‐derived essentially contributes creation habitats origin and, thus, multifunctionality plants, ultimately ecosystems.

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.

Phytoremediation technologies and their mechanism for removal of heavy metal from contaminated soil: An approach for a sustainable environment

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Янв. 27, 2023

The contamination of soils with heavy metals and its associated hazardous effects are a thrust area today’s research. Rapid industrialization, emissions from automobiles, agricultural inputs, improper disposal waste, etc., the major causes soil metals. These contaminants not only contaminate but also groundwater, reducing land hence food quality. enter chain have severe effect on human health. It is important to remove these soil. Various economic ecological strategies required restore contaminated Phytoremediation an emerging technology that non-invasive, cost-effective, aesthetically pleasing. Many metal-binding proteins (MBPs) plants significantly involved in phytoremediation metals; MBPs include metallothioneins; phytochelatins; metalloenzymes; metal-activated enzymes; many metal storage proteins, carrier channel proteins. Plants genetically modified enhance their capacity. In Arabidopsis , expression mercuric ion-binding protein Bacillus megaterium improves accumulation efficiency enhanced when assisted microorganisms, biochar, and/or chemicals. Removing without challenging security almost impossible. As result, crop selections ability sequester provide high demand. This paper summarizes role plant plant–microbe interaction remediating Biotechnological approaches or genetic engineering can be used tackle problem contamination.

Multifaceted roles of flavonoids mediating plant-microbe interactions

Microbiome, Год журнала: 2022, Номер 10(1)

Опубликована: Дек. 16, 2022

Plant-microbe interactions dynamically affect plant growth, health, and development. The mechanisms underpinning these associations are-to a large extent-mediated by specialized host-derived secondary metabolites. Flavonoids are one of the most studied classes such metabolites, regulating both development interaction with commensal microbes. Here, we provide comprehensive review multiple roles flavonoids in mediating plant-microbe interactions. First, briefly summarize general aspects flavonoid synthesis, transport, exudation plants. Then, importance influencing overall community assembly plant-root microbiomes. Last, highlight potential knowledge gaps our understanding how determine between plants Collectively, advocate advancing research this area toward innovative strategies to effectively manipulate plant-microbiome composition, case, via production roots.

Abstract Background Understanding the genetic and environmental factors that structure plant microbiomes is necessary for leveraging these interactions to address critical needs in agriculture, conservation, sustainability. Legumes, which form root nodule symbioses with nitrogen-fixing rhizobia, have served as model plants understanding genetics evolution of beneficial plant-microbe decades, thus added value models plant-microbiome interactions. Here we use a common garden experiment 16S rRNA gene amplicon shotgun metagenomic sequencing study drivers microbiome diversity composition three genotypes legume Medicago truncatula grown two native soil communities. Results Bacterial decreased between external (rhizosphere) internal compartments (root endosphere, leaf endosphere). Community was shaped by strong compartment × origin genotype interactions, driven significant effects rhizosphere endosphere. Nevertheless, all were dominated Ensifer , genus rhizobia forms symbiosis M. additional suggests nodulating not genetically distinguishable from those elsewhere plant. We also identify handful OTUs are tissues, likely colonized Conclusions Our results demonstrate host filtering effects, rhizospheres genetics, several key nodule-inhabiting taxa coexist range. set stage future functional experiments aimed at expanding our pairwise legume-rhizobium toward more mechanistic microbiomes.

While horticulture tools and methods have been extensively developed to improve the management of crops, systems harness rhizosphere microbiome benefit plant crops are still in development. Plants microbes coevolving for several millennia, conferring fitness advantages that expand plant's own genetic potential. These beneficial associations allow plants cope with abiotic stresses such as nutrient deficiency across a wide range soils growing conditions. achieve these benefits by selectively recruiting using root exudates, positively impacting their nutrition, health overall productivity. Advanced knowledge interplay between exudates alteration response status, underlying mechanisms there of, will development technologies increase crop yield.

The Chemistry of Stress: Understanding the ‘Cry for Help’ of Plant Roots

Metabolites, Год журнала: 2021, Номер 11(6), С. 357 - 357

Опубликована: Июнь 2, 2021

Plants are faced with various biotic and abiotic stresses during their life cycle. To withstand these stresses, plants have evolved adaptive strategies including the production of a wide array primary secondary metabolites. Some metabolites can direct defensive effects, while others act as chemical cues attracting beneficial (micro)organisms for protection. Similar to aboveground plant tissues, roots also appear "a cry help" response upon exposure stress, leading recruitment microorganisms help minimize damage caused by stress. Furthermore, emerging evidence indicates that microbial is, at least in part, mediated quantitative and/or qualitative changes root exudate composition. Both volatile water-soluble compounds been implicated important signals activation root-associated microbes. Here we provide an overview our current understanding belowground communication, particularly how stressed shape its protective microbiome.
