This study comprehensively examines diverse mechanisms through which contribute plant well-being, mitigate stress, facilitate phytoremediation processes. Microorganisms encompassing bacteria, fungi, archaea, viruses, have demonstrated their knack for stirring up growth-enabling hormones, activating pathways tuned ameliorating availability nutrients by means fixation solubilization Furthermore, such also display immense potential in field strategies aiding plants extraction, alteration, detoxification contaminants found both soil water. Complementing this, enable phytoextraction, rhizofiltration, phytostabilization, rhizodegradation, owing harmonious interaction with purification tainted environments. However, it is critical address legal issues, moral dilemmas, unintended consequences as are increasingly incorporated into sustainable agriculture methods. Optimizing microbial therapies ensuring appropriate use offers promising insights when leveraging cutting-edge technologies like omics genetic engineering. Coordination among academics, practitioners, policymakers still crucial quest a more robust peaceful coexistence microbes, plants, ecosystems.

The plant rhizosheath–root niche is an edaphic “mini-oasis” in hyperarid deserts with enhanced microbial competition

ISME Communications, Год журнала: 2022, Номер 2(1)

Опубликована: Июнь 3, 2022

Plants have evolved unique morphological and developmental adaptations to cope with the abiotic stresses imposed by (hyper)arid environments. Such include formation of rhizosheath-root system in which mutualistic plant-soil microbiome associations are established: plant provides a nutrient-rich shielded environment microorganisms, return improve plant-fitness through growth promoting services. We hypothesized that systems represent refuge niches resource islands for desert edaphic microbial communities. As corollary, we posited microorganisms compete intensively colonize such "oasis" only those beneficial improving host fitness preferentially selected plant. Our results show belowground micro-environment is largely more hospitable than surrounding gravel plain soil higher nutrient humidity contents, cooler temperatures. By combining metabarcoding shotgun metagenomics, demonstrated biomass community stability increased from non-vegetated soils system. Concomitantly, communities favored autotrophy lifestyle while associated were mainly heterotrophs enriched capacities. An intense inter-taxon competition involved colonization homeostasis rhizosheath zone, as documented significant enrichment antibiotic resistance genes CRISPR-Cas motifs. Altogether, our demonstrate "edaphic mini-oases" diversity hotspots hyperarid deserts. However, niches, therefore prepared outcompete potential rivals.

Potential of plant growth-promoting rhizobacteria to improve crop productivity and adaptation to a changing climate

CABI Reviews, Год журнала: 2023, Номер unknown

Опубликована: Янв. 13, 2023

Abstract Abiotic and biotic stresses negatively affect the growth yield of crops worldwide. It is estimated that abiotic account for global food crop losses 50% 30%, respectively. With rapidly growing world population expected to reach 10 billion by 2050, issue security becoming a concern. Climate change, which has its roots in industrialization, urbanization, agricultural activities, further exacerbates losses. Various innovative technologies, such as stress-tolerant varieties, smart irrigation systems, shifting cropping calendars, have been used both increase productivity mitigate effects various stresses, but most these strategies are time-intensive costly. Therefore, sustainable environmentally friendly, well economical, required face challenge providing world’s human with adequate food. In this context, plant growth-promoting rhizobacteria (PGPR) potential mitigating associated climate change. This approach can also improve sustainability agroecosystems reducing use unsustainable agrochemicals, contribute greenhouse gas emissions. review presents current information on how PGPR impacts security, mechanisms underlying PGPR-induced tolerance stresses.

Rhizosheath: Distinct features and environmental functions

Geoderma, Год журнала: 2023, Номер 435, С. 116500 - 116500

Опубликована: Май 12, 2023

Interactions between plant roots and the surrounding soils are crucial for growth soil health. The rhizosheath, which is sheath-like that tightly attached to root surface, increasingly acknowledged exhibit distinct features critical environmental functions soil, plants, microbes. However, differences terms "rhizosheath" "rhizosphere soil" remain ambiguous across literature, not all of rhizosheaths have reached a consensus. Here, we summarize terminology, methodology, formation mechanisms, findings via an integrated quantitative approach. First, propose comprehensive framework terminology different rhizosphere compartments, allows consistent definitions improved comparability studies. We also current knowledge mechanisms underlying rhizosheath formation. Moreover, by collecting evidence from highlight physical, chemical, microbial soils, such as 66% higher water content, 34% organic carbon, 56% water-extractable 71% biomass nitrogen in than those other counterparts. further discuss how these lead biogeochemical rhizosheaths, including sand fixation, aggregation, nutrient uptake, carbon dynamics, colonization. significance micro- ecosystem-scale. Finally, future research perspectives better understand harness benefits rhizosheaths.

Long-term plant residue retention can effectively replenish soil quality and fertility. In this study, we collected rhizosphere from the residual roots of annual Cenchrus fungigraminus in Ulan Buh Desert over past 10 years. The area, depth, length these decreased time. cellulose content was significantly higher later 5 years (2018–2022) than former (2013–2017), reaching its highest value 2021. lignin did not differ across samples except 2015 reached level total sugar 2022 227.88 ± 30.69 mg·g−1, which that other Compared to original sandy soil, organic matter microbial biomass carbon (SMBC) contents were 2.17–2.41 times 31.52–35.58% 3 (2020–2022) values 2020. also enhanced stocks 2018–2022.

The community assembly of arbuscular mycorrhizal fungi (AMF) in the rhizosphere results from recruitment and selection different AMF species with functional traits. aim this study was to analyze relationship between biotic abiotic factors four secondary vegetation (SV) plant a temperate forest. We selected sites at two altitudes, we marked five individuals per each site. Soil samples were collected SV species, during rainy dry seasons. analyzed for spores, organic matter (OM), pH, soil moisture, available phosphorus, nitrogen. Three ecological filters influenced assembly: host identity, factors, co-occurrence. This consisted 61 β-diversity values among across seasons altitudes. Canonical correspondence analysis revealed that composition is linked OM P N, only few co-occurring, while most do not. Our highlights how shape structure, which essential understanding environmental affect
