Rhizosphere bacterial community is mainly determined by soil environmental factors, but the active bacterial diversity is mainly shaped by plant selection

The assembly of the rhizosphere community, even diazotroph is mainly shaped by soil environmental factors (including climate and physiochemical characteristics) plant selection. To better understand driving forces on active overall nitrogen-fixing bacterial community compositions, we characterized communities tobacco collected from three sampling sites with a large geographic scale (> 600 km). results indicate that diversity composition are obviously differed according to sites. Still, no significant difference found between in rootzone samples. Climate variables including mean annual precipitation (MAP) temperature (MAT), characteristics available nitrogen (AN), potassium (AK) pH main affect structures Furthermore, MAP MAT, AN phosphorus (AP), total (TN) organic carbon (OC), AK electrical conductivity (EC) showed similar effects, but independent effect bacteria communities. However, alpha indices higher than samples, differences observed among different Proteobacteria predominant phylum all samples for bacteria. Escherichia-Shigella, Achromobacter, Streptomyces Sphingomonas dominant genera, Bradyrhizobium, Skermanella Extensimonas genera rhizosphere. high abundance Escherichia-Shigella low Ralstonia root-knot nematode infection wilt disease endemic risk. These contribute more assemblage, contributes community. Our study provides novel knowledge assemble across geographical scale.

Screening and Evaluation of Actinomycetes B-35 from Rhizosphere of Salvia miltiorrhiza Bunge and Its Biocontrol and Growth-Promoting Effects

Agronomy, Год журнала: 2025, Номер 15(1), С. 102 - 102

Опубликована: Янв. 1, 2025

Salvia miltiorrhiza Bunge (S. miltiorrhiza) is one of the most commonly used bulk herbs in China; however, root rot can seriously affect its quality and yields. To minimize use chemical pesticides for managing this plant fungal disease, biological control utilizing microbial bio-pesticides offers a promising alternative. This study aimed to enhance biocontrol resources available combating S. by isolating actinomycetes with antifungal activity from rhizosphere soil identifying preventive effect on rot. A total 35 were successfully screened miltiorrhizae. The strain B-35 strongest was out through antagonizing pathogen Fusarium solani miltiorrhiza, morphology 16S rRNA analysis. antagonistic fermentation filtrate crude extract could significantly destroy mycelium spores solani; mature rhizome reached 83.3%, number leaves, height biomass treatment group increased compared group. has certain application potential promotion sourced been demonstrated first time, potentially enhancing future crop production.

Small molecule metabolites drive plant rhizosphere microbial community assembly patterns

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Опубликована: Фев. 11, 2025

The assembly of rhizosphere microbial communities is essential for maintaining plant health, yet it influenced by a wide range biotic and abiotic factors. key drivers shaping the composition these communities, however, remain poorly understood. In this study, we analyzed 108 samples evaluated root traits, growth characteristics, soil enzyme activities, metabolites, chemical properties to identify primary determinants community assembly. Across 36 samples, obtained 969,634 high-quality sequences, clustering into 6,284 ASVs predominantly classified Proteobacteria (57.99%), Actinobacteria (30%), Bacteroidetes (5.13%). Our findings revealed that metabolites accounted more variance in compared (ANOVA, F = 1.53, p 0.04), or traits 1.04, 0.001). Seven small molecule including glycerol, sorbitol, phytol, alpha-ketoglutaric acid, were significantly correlated with βNTI, underscoring their role as critical genus Rhizobium , associated βNTI (R 0.25, 0.009), emerged keystone taxon structure. Soil culture experiments further validated can modulate ST treatment, enriched produced 1,032,205 sequences exhibited significant shifts (Adonis, 0.001, R 0.463), showing higher abundance control (CK). Variable selection (βNTI >2) drove phylogenetic turnover ST, while stochastic processes (|βNTI| < 2) dominated CK. This study provides quantitative insights highlights potential targeted modulation microbiomes.
