Soil contamination with heavy metals, particularly in rhizosphere regions, presents significant environmental and ecological challenges. Diverse bacterial communities found the rhizosphere, small area of soil that is impacted by plant roots, are critical for metal detoxification, organic matter breakdown, nutrient cycling. This research investigates community dynamics Cu (copper)-contaminated Elsholtzia splendens. Using metagenomic analysis, 28 phyla were identified, 7 dominant contaminated soils. The composition diversity to be most significantly influenced pH out all parameters examined, including concentration, Total Organic Carbon (TOC), total nitrogen, pH, moisture content, temperature, texture. Changes microbial those can efficiently evaluated using Bray-Curtis dissimilarity, which used quantify differences between based on species abundance. findings reveal taxonomic composition; Proteobacteria was abundant phylum, constituting 45.2% Furthermore, Firmicutes increased from 18.3% 22.1% soils, while Pseudomonas abundance rose 11.5% 18.3%. Metagenomic profiling also revealed functional gene pathways associated tolerance related copper efflux oxidative stress responses, more prevalent highlights functions metal-contaminated rhizospheres, enhancing understanding adaptation bioremediation potential.
