Introduction The rhizosphere is the zone of soil surrounding plant roots that directly influenced by root exudates released plant, which select microorganisms. resulting microbiota plays a key role in health and development enhancing its nutrition or immune response protecting it from biotic abiotic stresses. In particular, growth-promoting rhizobacteria (PGPR) are beneficial members this represent great hope for agroecology, since they could be used as bioinoculants sustainable crop production. Therefore, necessary to decipher molecular dialog between PGPR order promote establishment rhizosphere, required their functions. Methods Here, ability rapeseed ( Brassica napus ), pea Pisum sativum ryegrass Lolium perenne ) attract feed three Bacillus subtilis , Pseudomonas fluorescens Azospirillum brasilense was measured compared, these responses involved microbiota. Results Our results showed differentially attracted fed PGPR. For all bacteria, were most attractive induced fastest growth, while allowed highest biomass performance generally lower, variable observed bacteria. addition, P. A. appeared respond more efficiently than B. . Finally, we proposed evaluate compatibility each plant–PGPR couple assigning them “love match” score, reflects enhance bacterial rhizocompetence. Discussion Taken together, our provide new insights into specific selection through may help effective bioinoculant rhizosphere.

A Comparative Analysis of Bacterial and Fungal Communities in Coastal and Inland Pecan Plantations

Microorganisms, Journal Year: 2024, Volume and Issue: 12(7), P. 1313 - 1313

Published: June 27, 2024

Pecan forests (Carya illinoinensis) are significant contributors to both food and oil production, thrive in diverse soil environments, including coastal regions. However, the interplay between microbes pecan forest health environments remains understudied. Therefore, we investigated bacterial fungal diversity (Dafeng, DF) inland (Guomei, GM) plantations using high-throughput sequencing. The results revealed a higher microbial DF plantation than GM plantation, significantly influenced by pH edaphic factors. dominant phyla were Proteobacteria, Acidobacteriota Bacteroidota Acidobacteriota, Verrucomicrobiota plantation. Bacillus, Nitrospira UTCFX1 more abundant genera soil, whereas Candidatus Udaeobacter, HSB_OF53-F07 ADurbBin063-1 prevalent soil. Basidiomycota dominated sequences with relative abundance of Ascomycota Significant differences genus composition observed plantations, Scleroderma, Hebeloma, Naucoria being Clavulina, Russula, Inocybe A functional analysis greater carbohydrate metabolism potential bacteria ectomycorrhizal fungi Significantly positive correlations detected certain total soluble salt content, suggesting their role adaptation saline–alkali stress mitigation. These findings enhance our understanding microbiomes anticipated foster ecologically sustainable agroforestry practices contribute marshland ecosystem management.

Bacillus subtilis Strain YJ-15, Isolated from the Rhizosphere of Wheat Grown under Saline Conditions, Increases Soil Fertility and Modifies Microbial Community Structure

Microorganisms, Journal Year: 2024, Volume and Issue: 12(10), P. 2023 - 2023

Published: Oct. 6, 2024

Soil salinization during wheat cultivation considerably diminishes soil fertility and impedes growth, primarily due to rhizosphere microbial community changes. Our study investigates the application of
