Alfalfa (Medicago sativa L.) is an outstanding species used for the remediation of heavy metal-contaminated soil, and our previous research has shown that PGPR can promote plant growth under high-concentration lead stress. This discovery forced scientists to search strains compatible with alfalfa develop innovative bioremediation strategy lead-contaminated soil. study lead-tolerant rhizosphere soil red clover as experimental material; cultured, isolated, screened 52 excellent bacteria growth; then inoculated them into alfalfa. Marked differences existed in secretion auxin, protease, ACC deaminase among these strains. The results indicated Pseudomonas spp. (strain Y2), Y22), Bacillus Y23) exhibited a strong growth-promoting ability alfalfa, there was no antagonistic reaction three strains, enabling their coexistence. pot experiment manifested Y2, Y22, Y23, YH (a mixture could increase height, root length, fresh dry weight above ground, below ground They all significantly raise chlorophyll content antioxidant enzyme activity (p < 0.05) malondialdehyde (MDA) Furthermore, concurrent inoculation distinct types rhizobacteria (PGPR) diminished (Pb) concentrations enhanced levels available potassium (AK) phosphorus (AP), augmented capacity plants absorb Pb. imply be employed facilitate microbial-assisted other establish basis further on mechanism plants.

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 &lt; 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.
