The global population (presently 8.1 billion) is expanding exponentially at a rate of 1.59% every year, and it expected to reach 9 billion people by 2050. This rapid growth, coupled with significant development, presents major concern for feeding the population, as food production only predicted increase 70% Microbial technology branch biotechnology that advances ecological agriculture combining microorganisms emerging techniques. A key driver abiotic stress, which negatively impacts agricultural productivity an irreversible level threatens sustainable agriculture, climate challenge. Saline, drought, severe heat, other stresses induced change adversely affect morphological, physiological, biochemical, metabolic features plants. ultimately inhibits plant productivity. However, excessive use improper application agrochemicals are detrimental preservation environment natural resources, impeding development agriculture. Due their capacity enhance soil quality confer stress tolerance on plants, plant-growth-promoting bacteria (PGPB) can be used promote through expansion contemporary In this study, we aimed explore potential newly isolated microbial strains phytohormone production, organic acid generation, oxidative tolerance. microbes were selected based traits, phytohormones manipulated. results revealed all could produce different amounts acids

Abstract Introduction With the rapid development of microbial technology, inoculant is considered as a promising tool in sustainable agricultural systems. Mechanisms by which inoculants improve crop yield include improving plant nutrient availability and alleviating abiotic/biotic stresses (e.g., drought, salt disease). However, field efficacy remains inconsistent, constrains large‐scale adoptions. Identity dominant mechanisms that underpin positive impacts different limited. Thus, comprehensive quantitative assessment known on performance needed to provide guidance for effective tools from both research commercial perspectives. Materials Methods Based 97 peer‐reviewed publications, we conducted meta‐analysis quantify benefits yield, identify key enhanced yield. Results Result showed (i) alleviation was major mechanism (53.95%, n = 53) enhance while accounted 22.25% ( 58) enhancement. (ii) Pseudomonas most enhancing through (63.91%, 15), whereas Enterobacter (27.12%, 5). (iii) Considering together, (49.94%, 21), (27.55%, 13) Bacillus (25.66%, 32) were largest sources combination diazotroph Burkholderia with its legume host had highest effect (by 196.38%). Microbial also nutritional quality mineral contents produce. Conclusion Our analysis provides evidence can productivity be used either alone or reduced amount agrochemicals promote agriculture.

The present study to investigate effect arbuscular mycorrhizal fungi (AMF) biochar on root morphological traits, growth, physiological traits in soybean under water stress. Impact AMF spores number soil enzymes' activities were studied drought conditions. After 40 days, plant growth parameters measured. negatively affected parameters, microbial biomass, enzyme activities. Biochar individually increase significantly (plant height, dry weight, nodule number), such as diameter, surface area, total length, volume, projected chlorophyll content, nitrogen content over control In conditions, dual applications enhanced shoot chlorophyll, contents than control.

Abstract Drought is a major abiotic stress limiting agricultural productivity. Previous field-level experiments have demonstrated that drought decreases microbiome diversity in the root and rhizosphere. How these changes ultimately affect plant health remains elusive. Toward this end, we combined reductionist, transitional ecological approaches, applied to staple cereal crop sorghum identify key root-associated microbes robustly drought-stressed phenotypes. Fifty-three Arabidopsis-associated bacteria were seeds their effect on growth was monitored. Two Arthrobacter strains caused inhibition (RGI) Arabidopsis sorghum. In context of synthetic communities, Variovorax able protect plants from Arthrobacter-caused RGI. As system, high-throughput phenotyping used test communities. During stress, colonized by had reduced leaf water content. Plants both performed as well or better than control plants. parallel, field trial wherein evaluated across conditions. By incorporating data soil properties into analysis, accounted for experimental noise with novel method observe negative correlation between abundance growth. Having validated approach, cross-referenced datasets report list high confidence positively associated under stress. conclusion, three-tiered system successfully spanned lab-to-field gap identified beneficial deleterious bacterial drought.

Seven Bacillus spp. isolated from the marine water and rhizosphere of medicinal plant Coscinium fenestratum were studied to produce growth promotion (PGP) traits invitro. Among seven isolates, MMRH22 RHPR20 produced copious amounts PGP traits. Based on 16S rRNA sequence, two potent bacterial MMRH22, identified as mojavensis cereus, respectively. A compatibility test between isolates revealed they are compatible can be used a consortium. Both evaluated for biofortification sorghum under greenhouse conditions. Treatments included application RHPR20, their consortium (RHPR20 + MMRH22), an uninoculated control.
