Abstract Soil hosts diverse microbial communities including bacteria, fungi, archaea, protozoans and nematodes among others, which are fundamental to sustainable agriculture drive essential processes that underpin soil fertility, plant health, ecosystem resilience. They promote growth through mechanisms like nitrogen fixation, phosphorus solubilization, production of growth-promoting substances, enhancement nutrient uptake, improvement structure detoxification harmful substances. Recently, there has been increasing interest in utilizing microorganisms improve health boost efficiency, despite limited understanding diversity, microbe-plant interactions, translating laboratory findings field conditions. This is driven by the urgent need feed growing global population, placing pressure on arable land produce high-quality yields. Conventionally, synthetic fertilizers have extensively used provide nutrients, growth, increase crop productivity. Although revolutionized since green revolution, their overuse significantly harmed reduced review synthesizes current knowledge microbes influence agricultural practices, with a focus cycling plant–microbe interactions. We discuss functions important groups, such as nitrogen-fixing phosphorus-solubilizing bacteria (PSB), fungi. Furthermore, we factors highlight gaps future research maximize potential use agriculture. Understanding significance key increases harnessing vital contributors

In this study, we have isolated a bacterial endophyte Paenibacillus dendritiformis strain RAE13 (Accession number: OR259131) from the leaves of Tecomella undulata (Roheda) plant. The identification species was carried out using 16s-rDNA ribotyping. Subsequently, gauged for its potential to endorse plant growth through various mechanisms such as nitrogen fixation, IAA production, HCN synthesis, siderophore generation, and ammonia production. Furthermore, evaluation focused on endophyte's capacity producing extracellular enzymes, including cellulase, chitinase, protease, amylase, catalase. exhibited synthesize an average 18±0.375 μg/ml indole-3-acetic acid (IAA) after being subjected concentration 5 mg/ml tryptophan over 14-day incubation period. endophytic isolate RAE 13 produced 42.4±0.004 Gibberellin, solubilized phosphate in range 70.2 135.5 μg/ml, 45.5 ammonia. phylogenetic analysis unveiled that had common ancestor maximum nucleotide sequence similarity 98.30% with sp isolates Uttar Pradesh, India. To diminish consumption chemicals conventional farming, results indicated great growth-stimulating inoculant. Henceforward, utilization these enzymes medical industrial applications will be highly beneficial. Additionally, it could enhance tolerance challenging environmental circumstances drought high temperatures.

Introduction The strategic utilization of plant growth-promoting (PGP) rhizospheric bacteria is a sustainable approach to mitigating the negative effects anthropogenic activities and excessive nickel (Ni) accumulation in plants. Given that specific symbiotic interactions depend on direct relationship between species, bacterial strain, heavy metals (HMs), this study aimed investigate Paraburkholderia phytofirmans PsJN seed priming Ni tolerance adult Micro-Tom tomato plants ( Solanum lycopersicum L .). Methods Sterilized seeds were bioprimed with P. for 24 hours then sown into soil. Non-primed, imbibed used as control. After 10 days, seedlings transferred Hoagland nutrient solution. Chronic (10 μM Ni) acute (50 stress conditions induced by supplementing solution salt. experiment lasted approximately 75 covering complete life cycle Various physiological biochemical parameters analyzed. Results Significant differences p < 0.05) observed non-primed terms fruit yield. Bioprimed tomatoes exhibited higher resilience stress, particularly under conditions. Non-primed treated 50 showed statistically lower concentrations chlorophyll total chlorophylls compared tomatoes. Moreover, proline content was generally more stable plants, indicating reduced oxidative stress.The activity antioxidant enzymes distinct patterns nonprimed Conclusion findings suggest biopriming enhances growth stress. This technique appears mitigate Ni-induced effects, at concentrations, making it promising strategy improving performance Ni-contaminated environments. Future studies should explore underlying molecular mechanisms field applications approach.

Plant growth-promoting bacteria (PGPB) are free-living microorganisms that actively reside in the rhizosphere and affect plant growth development. These employ their own metabolic system to fix nitrogen, solubilize phosphate, secrete hormones directly impact metabolism of plants. Generating sustainable agricultural production under various environmental stresses requires a detailed understanding mechanisms use promote growth. In present study, Pseudomonas aeruginosa (MW843625), PGP soil bacterium with minimum inhibitory concentration (MIC) 150 mM against fluoride (F), was isolated from fields Chhattisgarh, India, assessed for remedial potential. This study concentrated on biomass accumulation, nutrient absorption, oxidative stress tolerance plants involving antioxidative enzymes. By determining MDA accumulation ROS (O2•− H2O2) Oryza sativa L. F (50 ppm) stress, assessed. The results showed inoculation P. enhanced ability O. seedlings absorb nutrients increased amounts total chlorophyll (Chl), soluble protein, biomass. contrast cultivated F-stress alone, those inoculated along considerably reduced concentrations roots, shoots, grains. alleviation deleterious effects owing has been associated improved activity/upregulation genes (SOD, CAT, APX) comparison only F-subjected plants, which resulted lower O2•−, H2O2, content. Additionally, it also reflected our potential increase activities enzymes such as urease, phosphatase, dehydrogenase, nitrate reductase, cellulase. Accordingly, findings conducted suggest can be exploited not an ideal candidate bioremediation but enhancing fertility promotion development contamination.
