Plant health is necessary for food security, which a key determinant of secure and sustainable production systems. Deficiency soil nutrients invasion plant pathogens or insects are the main destroyers world’s production. Synthetic fertilizers chemical-based pesticides frequently employed to combat problems. However, these have negative impacts on microbial ecosystems ecosystem functioning. Rhizosphere microorganisms demonstrated their potency improve manage encourage growth, resulting in increased yield quality by converting organic inorganic substances around rhizosphere zone into available nutrients. Besides regulating nutrient availability growth enhancement, rhizobacteria fungi can restrict that cause disease secreting inhibitory chemicals boosting immunity pests pathogens. Thus, viewed as viable, alluring economic approaches agriculture biofertilizers biopesticides. This review provides an overview role inducing defenses. Moreover, discussion presented surrounding recent consequences employing strategy towards improving fertilization effectiveness, encouraging stronger, more pest-resistant plants.

Abstract Soils are a main repository of biodiversity harbouring immense diversity microbial species that plays central role in fundamental ecological processes and acts as the seed bank for emergence plant microbiome cropland ecosystems. Crop‐associated microbiomes play an important shaping performance, which includes but not limited to nutrient uptake, disease resistance, abiotic stress tolerance. Although our understanding structure function soil has been rapidly advancing, most knowledge comes from ecosystems natural environment. In this review, we present overview current communities along soil–plant continuum agroecosystems. To characterize mechanisms community assembly crop microbiomes, explore how host environmental factors such developmental stage, pathogen invasion, land management shape structure, co‐occurrence patterns, crop‐microbiome interactions. Particularly, relative importance deterministic stochastic is illustrated under different conditions, potential sources keystone taxa described.

The Arabidopsis holobiont: a (re)source of insights to understand the amazing world of plant–microbe interactions

Environmental Microbiome, Journal Year: 2023, Volume and Issue: 18(1)

Published: Feb. 17, 2023

Abstract As holobiont, a plant is intrinsically connected to its microbiomes. However, some characteristics of these microbiomes, such as their taxonomic composition, biological and evolutionary role, especially the drivers that shape them, are not entirely elucidated. Reports on microbiota Arabidopsis thaliana first appeared more than ten years ago. there still lack comprehensive understanding vast amount information has been generated using this holobiont. The main goal review was perform an in-depth, exhaustive, systematic analysis literature regarding Arabidopsis–microbiome interaction. A core identified composed few bacterial non-bacterial taxa. soil (and, lesser degree, air) were detected primary microorganism sources. From perspective, species, ecotype, circadian cycle, developmental stage, environmental responses, exudation metabolites crucial factors shaping plant–microbe microbial microbe-microbe interactions, type microorganisms belonging (i.e., beneficial or detrimental), metabolic responses also key drivers. underlying mechanisms just beginning be unveiled, but relevant future research needs identified. Thus, provides valuable novel analyses will shed light deepen our holobiont interaction with environment.

Plant and soil microbiomes are integral to the health productivity of plants ecosystems, yet researchers struggle identify microbiome characteristics important for providing beneficial outcomes. Network analysis offers a shift in analytical framework beyond “who is present” organization or patterns coexistence between microbes within microbiome. Because microbial phenotypes often significantly impacted by coexisting populations, likely be especially predicting functional Here, we provide an overview how why network research, highlighting ways which analyses have provided novel insights into capacities, diverse roles different eco-evolutionary dynamics plant microbiomes.

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(12), P. 9879 - 9879

Published: June 8, 2023

Phosphorus (P) is the second most important macronutrient for crop growth and a limiting factor in food production. Choosing right P fertilizer formulation production systems because not mobile soils, placing phosphate fertilizers major management decision. In addition, root microorganisms play an role helping phosphorus fertilization by regulating soil properties fertility through different pathways. Our study evaluated impact of two phosphorous formulations (polyphosphates orthophosphates) on physiological traits wheat related to yield (photosynthetic parameters, biomass, morphology) its associated microbiota. A greenhouse experiment was conducted using agricultural deficient (1.49%). Phenotyping technologies were used at tillering, stem elongation, heading, flowering, grain-filling stages. The evaluation revealed highly significant differences between treated untreated plants but fertilizers. High-throughput sequencing applied analyse rhizosphere rhizoplane microbiota tillering alpha- beta-diversity analyses bacterial fungal fertilized non-fertilized wheat, rhizosphere, rhizoplane, provides new information composition during stages (Z39 Z69) under polyphosphate orthophosphate fertilization. Hence, deeper understanding this interaction could provide better insights into managing microbial communities promote beneficial plant-microbiome interactions uptake.

Differential Responses of Methylobacterium and Sphingomonas Species to Multispecies Interactions in the Phyllosphere

Environmental Microbiology, Journal Year: 2025, Volume and Issue: 27(1)

Published: Jan. 1, 2025

ABSTRACT The leaf surface, known as the phylloplane, presents an oligotrophic and heterogeneous environment due to its topography uneven distribution of resources. Although it is a challenging environment, leaves support abundant bacterial communities that are spatially structured. However, factors influencing these spatial patterns not well understood. To study changes in population density bacteria synthetic communities, behaviour two common groups Arabidopsis thaliana microbiota— Methylobacterium (methylobacteria) Sphingomonas (sphingomonads)—was examined. Using consisting or three species, hypothesis was tested presence third species affects interaction other species. Results indicated methylobacteria exhibit greater sensitivity densities patterns, with higher intra‐genus competition lower aggregation compared sphingomonads. Pairwise comparisons were insufficient explain shifts observed three‐species suggesting higher‐order interactions influence structuring complex communities. This emphasises role multispecies determining community dynamics on phylloplane.

Influences of plant maternal effects, chemotype, and environment on the leaf bacterial community

Plant Biology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Abstract Plant individuals within a species can differ markedly in their leaf chemical composition, forming so‐called chemotypes. Little is known about whether such differences impact the microbial communities associated with leaves and how different environmental conditions may shape these relationships. We used Tanacetum vulgare as model plant to study impacts of maternal effects, terpenoid chemotype, environment on bacterial community by growing clones field greenhouse. hypothesized that all three factors affect profiles well chemodiversity diversity are correlated. The results revealed was significantly influenced effects (field vs. greenhouse), but not profile. There also no evidence for correlation between composition diversity. Overall, higher number unique amplicon sequence variants were found grown under than those identified interactions individual terpenoids specific members community. Our suggests has, overall, little effect community, some might beneficial species. While more studies needed investigate relationship microbiomes, our highlight importance integrating chemodiversity, understanding plant–microbiome interactions.
