Zinc (Zn) is essential for optimal plant growth and nutrition, while zinc-solubilizing bacteria (ZSB) enhance accessibility to zinc by converting its insoluble forms into usable ones. The primary objective of this research was isolate identify Zn-solubilizing strains from the onion rhizosphere evaluate their ability solubilize different Zn compounds, including ZnO, ZnCO3, Zn3(PO4)2. Of nineteen bacterial isolates retrieved, fifteen demonstrated inorganic compounds based on plate assay techniques. strains, selected qualitative properties, underwent quantitative testing in broth culture using atomic absorption spectrophotometry (AAS) Field Emission-Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (FE-SEM-EDS). Seven a high capacity were identified 16S rRNA gene amplification sequence analysis. These affiliated Pantoea eucrina, dispersa, Pseudomonas aeruginosa, Bacillus velezensis, fluorescens. Notably, study first report potential eucrina as ZSB. strain ZSC9 exhibited maximum solubilization index (8.85) highest soluble content (624 mg L−1) among three ZnO being most effectively solubilized 10th day incubation ZnO-enriched basal medium. All more effective at solubilizing than ZnCO3 Zn3(PO4)2, led significant drop pH broth. showed reduction (3.82) ZnO-supplemented medium, indicating negative correlation between solubilization. ZSB assessed under pot house conditions. results that inoculating seedlings these significantly improved growth. Among tested, ZSC9, ZSC10, ZSC17 effective, enhancing attributes such height, bulb diameter, fresh dry weight bulbs, uptake plant, overall yield compared other strains. findings suggest have great biofertilizers development.

Climate change and agriculture are intrinsically connected sudden changes in climatic conditions adversely impact global food production security. The climate change-linked abiotic stressors like drought high temperatures resulting crop failure. most severe stress significantly affect the stomatal closure, of reactive oxygen species, transpiration, photosynthesis or other physiological processes plant morphology, growth yield. Therefore, there is an exigent need for cost effective eco-friendly modern technologies to induce tolerance plants leading climate-adapted sustainable agricultural practices sustained production. Among many options being pursued this regard, use promoting microbes (PGPMs) approach promote resilience better productivity. These PGPMs confer resistance via various direct indirect mechanisms including antioxidants, enzymes, exopolysaccharides, modulation phytohormones level, osmotic adjustment by inducing accumulation sugars, along with increases nutrients, water uptake photosynthetic pigments. However, several technological ecological challenges limit their sometimes treatment beneficial fails produce desired results under field conditions. Thus, development synthetic microbial communities host mediated microbiome engineering transgenic capacity express traits may survival present review critically assesses research evidence on potentials genes as develop resilient increased Effective collaboration among scientific communities, policymakers regulatory agencies needed create strong frameworks that both regulate utilization agriculture.
