Soil Microbial Mechanisms to Improve Pear Seedling Growth by Applying Bacillus and Trichoderma‐Amended Biofertilizers

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 27, 2025

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.

Microbial diversity in coastal Casuarina equisetifolia forest and its potential in counteracting bacterial wilt infections

Pest Management Science, Journal Year: 2025, Volume and Issue: unknown

Published: April 9, 2025

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.

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).

Investigating protistan predators and bacteria within soil microbiomes in agricultural ecosystems under organic and chemical fertilizer applications

Biology and Fertility of Soils, Journal Year: 2024, Volume and Issue: 60(7), P. 1009 - 1024

Published: July 20, 2024

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.

Comparing the Environmental Influences and Community Assembly of Protist Communities in Two Anthropogenic Coastal Areas

Microorganisms, Journal Year: 2024, Volume and Issue: 12(8), P. 1618 - 1618

Published: Aug. 8, 2024

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.
