Introduction Global mining activities have significant impacts on ecosystems, but most studies focused only the relationship between soil physicochemical properties and microbial diversity in soils. The present study provides an insight into effects of physico-chemical endophytic bacterial community composition rhizosphere three different crops. Methods Musa basjoo Siebold L., Amygdalus persica Triticum aestivum L. were collected from inter-root soils plant roots to determine communities root system. Results results showed that resulted acidification, altered trace element content increased organic carbon. There was increase Ascomycota Actinobacteria phylum crop bacteria. Interestingly, chao1 shannon indices endophytes significantly elevated compared contro ( p < 0.05). Among them, highest level richness environment. environment functional enrichment histidine kinases oxidoreductases community. total potassium (TK) soil, as well Fe Pb content, positively correlated with α-diversity index Streptomyces . Zn Ti negatively index. Discussion This data support for exploring mechanisms response developing ecological restoration strategies areas.

Crop Cultivation Reshapes Soil Microbiomes to Drive Heavy Metal Mobilization in Restored Mining Areas

Agriculture, Journal Year: 2025, Volume and Issue: 15(8), P. 804 - 804

Published: April 8, 2025

Mining activities cause substantial heavy metal release. Ecosystem restoration is considered one of the most effective ways to prevent mobilization in mining areas. Previous studies have suggested that microorganisms play crucial roles transport metal-contaminated farmland soils. However, interactions between geochemical fractions metals and microbial communities under crop cultivation restored areas are still unclear. In this study, we systematically collected soil (FS) grassland (GS) from a area reveal effects on composition microbiomes their potential mobilization. The results revealed exchangeable (Cd, Zn, As) FS (11%, 11%, 1.3% average, respectively) were significantly greater than those GS (30%, 19%, 3.2% respectively), indicating agricultural promoted addition, determined attributes, including diversity, composition, community structure, different GS. Furthermore, our such differences driven mainly by Notably, dominant genera enriched extensively involved mobilization, which consistent with fact metabolism-related genes FS. Taken together, findings suggest an important role
