ABSTRACT Bacillus velezensis SQR9 or Trichoderma harzianum NJAU4742‐amended bioorganic fertilizers might significantly improve the soil microbial community and crop yields. However, mechanisms these microorganisms act are far away from distinctness. We combined amplicon sequencing with culturable approaches to investigate effects of on pear tree growth, rhizosphere nutrients mechanisms. The T4742 treatments increased total biomass trees by 68% 84%, respectively, compared conventional organic fertilizer treatment (CK). tends increase matter available phosphorus, while more effectively enhances nitrogen, potassium, iron zinc levels. These were primarily linked changes in community. enriched twice as many differential microbes SQR9. Urebacillus , Streptomyces Mycobacterium abundance Pseudomonas Aspergillus Penicillium . In vitro experiments revealed that secondary metabolites secreted B. T. NJAU4742 stimulate growth key probiotics associated their respective treatments, enhancing fertility plant biomass. study specific roles agricultural applications, providing new insights for developing effective targeted products promoting sustainable agriculture.

Abstract BACKGROUND Casuarina wilt is a destructive soil‐borne disease caused by Ralstonia solanacearum species complex (RSSC). Recent large‐scale outbreaks of in the coastal regions Guangdong Province, China, suggest that originally resistant clones become susceptible to RSSC infection. This study aimed investigate microbial diversity environmental microorganisms and its potential biocontrol this devastating disease. RESULTS The results unveiled dominant common equisetifolia tree tissues, rhizosphere soils seawater vicinity forest belt. We also found range bacterial with potent antimicrobial activities against pseudosolanacearum . Both endophyte A1‐5, identified as Bacillus velezensis, combination agent named CEP consisting three mutually compatible soil isolates belonging Citrobacter farmeri , Enterobacter aerogenes Pseudomonas mosselii respectively, could effectively control R. infections on tomato. active substance strain A1‐5 inhibits growth was purified surfactin C. CONCLUSION findings their specific distributions areas, present useful clues resources for developing new strategies prevent wilt. © 2025 Society Chemical Industry.

ABSTRACT Soils contain diverse predatory protists that affect the abundance and behavior of rhizosphere bacteria, including bacteria may benefit plant health. Protists harbor their own bacterial microbiomes, we previously observed plants inoculated with harbored similar to those in protist inoculum. To determine how microbiomes rhizosphere, profiled eight isolates after 2 years laboratory culture. We then compared culture maize communities 6 weeks inoculation. Introduction enriched 13 protist-associated amplicon sequence variants (ASVs) which comprised ~10% community. Additional ASVs ranked highly both (top 100) 20) microbiomes; together, a median 47% microbiome was or high rank rhizosphere. Inoculation three out cultures positively affected root biomass traits, but mixture had no effect, indicating impact on growth is context dependent. Isolates positive negative effects culture, suggesting use multiple strategies survive proximity predators. This study demonstrates even long-term host can colonize maize. The findings also identify groups rhizosphere-colonizing persist among predators, suggests these could associate from soil. IMPORTANCE Understanding will be essential deploy sustainable agriculture. shows hosted distinct large proportion found colonizing environment were onto seedlings. certain for retain ability soil, might support survival absence plant.

Introduction Plant growth-promoting rhizobacteria (PGPR) and elevated CO 2 (eCO ) have demonstrated their individual potential to enhance plant yield quality through close interaction with rhizosphere microorganisms growth. However, the efficacy of PGPR under eCO on microbiome and, ultimately, active ingredient accumulation are not yet fully understood. Methods This study investigated how medicinal Pseudostellaria heterophylla ( P. its microbes respond Bacillus subtilis Pseudomonas fluorescens at (1,000 ppm). Results Discussion It was found that polysaccharides in tuber were significantly increased by 38 253%, respectively. promotion has been associated root development changes indigenous microbial community. Metagenomics analysis revealed a significant reduction pathogenic Fusarium abundance rhizosphere.

Abstract Organic farming can enhance biodiversity and soil health is a sustainable alternative to conventional farming. Yet, protists especially protistan predators, have received inadequate attention, their contributions the sustainability of organic remained underexplored. In this study, we examined microbial communities from 379 samples, including both chemically fertilized soils China. Our findings revealed higher bacterial diversity increases in plant-beneficial bacteria organically farmed soils. Notably, systems facilitated dynamic predator-prey interactions, which may be disrupted by application chemical fertilizers. Additionally, enriched enhancing relative abundance functional PGPR, thus improving health. We further conducted case study highlighting critical role matter sustaining predator populations interactions with bacteria. propose crucial inputs for supporting predators interplay predator-prey, ultimately functions promoting agricultural sustainability.

Anthropogenic stresses are intensively affecting the structure and function of microbial communities in coastal ecosystems. Despite being essential components ecosystems, environmental influences assembly processes protist remain largely unknown areas with severe disturbance. Here, we used 18S rRNA gene high-throughput sequencing to compare composition, process, functional from Northern Yellow Sea (NYS) Eastern Bohai (EBS). These two separated by Liaodong Peninsula experience different anthropogenic due varying degrees urbanization. We detected significant differences between areas. Environmental geographic factors both influenced composition communities, playing a greater role. The neutral community model indicated that was governed deterministic processes, stochastic having stronger influence EBS area compared NYS area. phototrophic consumer factors, differed significantly Our results provide insights into biogeography estuaries under stresses, which may inform future management.
