Rhizospheric bacterial communities in plants contribute to drought resilience by promoting plant-soil interactions, yet their biodiversity and ecological impacts are not fully characterized. In cowpeas, these interactions may be crucial enhancing tolerance conditions. this study, cowpea were subjected treatment, the soil attached roots was collected, environmental DNA (e-DNA) extracted, identified as amplicon sequence variants (ASVs) metagenomics analysis of 16S rRNA gene. Microbial under control conditions analyzed using taxonomy diversity metrics. The sequencing results revealed 5,571 ASVs, taxonomic 1,752 species. Alpha beta analyses showed less conserved microbial community structures compositions among samples isolated from rhizosphere compared untreated samples, implying enhancement effect on species’ richness. differential accumulation 75 species that accumulated significantly ( P ≤ 0.05) response drought, including 13 exclusively present, seven absent, 46 forming a high-abundance cluster within hierarchical heatmap. These also grouped into specific clades phylogenetic tree, suggesting common genetic ancestry potentially shared traits associated with tolerance. differentially list included previously characterized saline habitats. findings suggest stress alters composition abundance epiphytic communities, impacting rhizosphere’s balance cowpeas. highlight adaptations enhance plant through improved mitigation, providing meaningful understandings for advancing sustainable agriculture developing microbial-based strategies boost crop productivity drought-prone regions.

The interactions between plants and microbes are essential for enhancing crop productivity. However, the mechanisms underlying host-specific microbiome migration functional assembly remain poorly understood. In this study, from soil to leaves in rice (Oryza sativa) maize (Zea mays) was analyzed through 16S rRNA sequencing phenotypic assessments. When we used same source grow maize, microbiota traits were specifically enriched by its phyllosphere rhizosphere. This indicated that can selectively assemble microbiomes a shared source. Therefore, 22 strains isolated phyllospheres of construct synthetic microbial community (SynCom). growth inoculated with SynCom, belonging Bacillus compared phyllosphere. Additionally, strain Rhizobium rhizosphere These results suggest plant species influence within their respective compartments. Compared mock inoculation, SynCom inoculation significantly enhanced growth. microbiomes, Achromobacter, which assembled both played role Our findings underscore importance dynamics leveraging plant–microbe sustainable agriculture.

Tropical grassland soils, especially those with alkaline properties, often exhibit limited phosphorus availability due to its precipitation in insoluble forms. Phosphate-solubilizing bacteria (PSB) and rhizobia have demonstrated their potential enhance the of this nutrient promote growth forage legumes. This study, conducted under controlled conditions a mesh house, evaluated effect co-inoculation PSB, including Micrococcus sp.
