Diversity of nifH Gene in Culturable Rhizobia from Black Locust (Robinia pseudoacacia L.) Grown in Cadmium-Contaminated Soils

Biology, Journal Year: 2025, Volume and Issue: 14(4), P. 362 - 362

Published: March 31, 2025

(1) Background: Rhizobia can promote plant growth by providing essential nutrients such as NH4+ and PO43−; thus, rhizobia that tolerate the stress of heavy metals will be conducive to phytoremediation heavy-metal-contaminated soils. Therefore, understanding dominant heavy-metal-tolerant cultured is important for establishment an indigenous legume–rhizobia symbiotic remediation system; (2) Methods: Here, we investigated nifH gene diversity in culturable from black locust (Robinia pseudoacacia L.) grown cadmium (Cd)-contaminated soils using high-throughput sequencing.; (3) Results: A total 16 genera 26 species were identified cultures root nodules exposed five Cd levels. Cadmium did not show a significant effect on abundance, diversity, evenness community. However, significantly affected community structure containing nifH. Mesorhizobium, Sinorhizobium, Rhizobium absolute present under treatments. Additionally, relative abundance Azohydromonas, Xanthobacter, Skermanella, Bradyrhizobium, Paenibacillus, Pseudacidovorax cultures. Soil pH, Cd, DTPA-Cd, C/H ratio factors community.; (4) Conclusions: showed negative locust, which provide insight into selection excellent strains

Diversity Analysis of Rhizosphere Microorganisms in Helichrysum arenarium (L.) Moench and Screening of Growth-Promoting Bacteria in Xinjiang, China

Microbiology Research, Journal Year: 2025, Volume and Issue: 16(5), P. 89 - 89

Published: April 25, 2025

Rhizosphere microorganisms effectively exploit nutrient resources within the rhizosphere, while growth-promoting bacteria in this environment play a vital role regulating soil fertility and enhancing plant health. In study, we utilized comprehensive approach that included isolation, purification, identification of dominant microorganisms, alongside high-throughput sequencing technology. This methodology was employed to analyze primary microbial groups their diversity rhizosphere Helichrysum arenarium (L.) Moench Altay, Xinjiang, China. By isolating bacterial strains from using dilution coating method, successfully obtained 43 distinct strains. Subsequently, selective media were screen for characteristics among these isolated derived H. Moench. The results, through amplification sequencing, revealed diverse communities belonging 35 phyla, 93 orders, 215 families, 324 genera, 231 species associated with Moench, as well fungal comprising 14 47 96 204 571 present soil. Among identified communities, Actinobacteriota emerged predominant phylum Ascomycetes Mortieromycetes recognized principal phyla found rhizospheric Analysis culturable bacteria’s promotion activity indicated three strains—S16, S31, S29—exhibited highest solubility index inorganic phosphorus; additionally, screened S7 S10 demonstrated nitrogen-fixing capabilities. Furthermore, ten exhibiting excellent iron-bearing capacities identified; notably, strain S16 displayed D/d value indicating, its superior capacity. Kocuria rosea, Priestia megaterium, Bacillus mobilis, bataviensis, variants mycoides, paramobilis, sonorensis, Alcaligenes faecalis. study provides foundational understanding how influence release offers valuable insights into yield quality cultivation by isolating, screening, identifying
