It is important to improve soil properties promote healthy growth We isolated identified pathogenic Fusarium ramigenum from infected roots. then a new Bacillus paralicheniformis strain SYN-191 rhizosphere around roots, showed B. SYN-91 could inhibit F. growth, degrade proteins, dissolve silicate, decompose cellulose. treatment significantly improved agronomic traits seedlings continuous cropping soil. Furthermore, restructured microbiomes soil, including reducing number harmful fungi, such as Fusarium, increasing beneficial bacterial populations Pseudomonas. Field experiments that application increased yield by 26.47% (P < 0.01). Whole-genome sequencing revealed relevant genes for antibiotic synthesis, potassium dissolution, cellulose decomposition.

As carriers of direct contact between plants and the atmospheric environment, microbiomes phyllosphere microorganisms are increasingly recognized as an important area study. Salt secretion triggered by salt-secreting halophytes elicits changes in community structure functions microorganisms, often provides positive feedback to individual plant/community environment. In this study, contents Na+ K+ rhizosphere, plant Tamarix chinensis were increased under 200 mmol/L NaCl stress. The increase electrical conductivity, not only decreased diversity bacterial fungal communities, but also relative abundance Actinobacteriota Basidiomycota. Influenced conductivity Na+, bacteria–fungus co-occurrence network salt stress has higher complexity. Changes microbial further resulted a significant energy source pathotrophic groups. Acidobacteriota rhizosphere showed decreasing trend stress, while complexity was than that control. addition, abundances functional groups bacteria carbon cycle phosphorus significantly correlated with Na+. This study investigated effects salinity on physicochemical properties communities halophytes, highlights role microbes ecological indicators responses stressful environments.

Abstract Background Potato is a globally significant crop, but its intensive cultivation depends heavily on mineral fertilizers, leading to soil degradation, water pollution, increased production costs, and environmental harm. Microbial inoculants, composed of beneficial bacteria fungi, provide sustainable alternative enhancing nutrient availability, promoting plant health, growth. However, the specific mechanisms action these microorganisms their effects microbial communities functionality remain insufficiently understood. Methods This study aimed evaluate how inoculants affect prokaryotic fungal community composition, diversity, functionality, pathogen suppression in rhizosphere tuberosphere potato crop throughout full growing cycle. We investigated temporal changes microbiome (in tuberosphere) under different fertilization strategies: (F100), 50% reduced (F50), two treatments combining F50 with inoculant consisting Azospirillum, Bacillus Pseudomonas (F50 + BA), or containing Azotobacter, non-mycorrhizal fungi BAFU). Using estimated absolute abundance approach, which infers quantitative measurements from sequencing data, we monitored shifts cropping Results In rhizosphere, bioinoculated soils showed an increase along decline pathogens, without compromising yield. BAFU promoted bacterial taxa involved growth, resistance, (Allorhizobium, Devosia, Bacillus, Lysobacter, Massilia, Paenibacillus, Sphingomonas, Streptomyces). BA significantly pathogens such as Verticillium, Gibellulopsis, Phialophora, while Clonostachys, biocontrol fungus mycoparasitic properties. also enhanced key functions nitrogen fixation, ammonification, denitrification, cellulose CO₂ contributing improved fertility. Conclusion Our findings demonstrate potential enrich growth-promoting microorganisms, suppress sustain growth fertilization. highlights value promising strategy for more systems.

Despite the essential role of nitrogen fertilizers in achieving high crop yields, current application practices often exhibit low efficiency. Optimizing (N) fertilization agriculture is, therefore, critical for enhancing productivity while ensuring sustainable food production. This study investigates effects nitrification inhibitors (Nis) such as Dimethyl Pyrazole Phosphate (DMPP) and Fulvic Acid (DMPFA), plant growth-promoting bacteria inoculation, phosphorus (P) on soil-plant-microbe system maize. DMPFA is an organic inhibitor that combines DMP fulvic acid benefits both compounds a chelator. A comprehensive rhizobox experiment was conducted, employing varying levels P, inoculant types, Nis, to analyze influence these factors various soil properties, maize fitness, phenotypic traits, including root architecture exudate profile. Additionally, examined treatments bacterial fungal communities within rhizosphere roots. Our results showed use Nis improved nutrition biomass. For example, significantly efficiency by up 29%, increased P content 37%, raised concentration shoot 26%, compared traditional ammonium treatments. The microbial inhabiting roots were also highly influenced different Among them, N treatment major driver shaping compartments. Notably, reduced abundance groups involved process. Moreover, we observed each experimental employed this investigation could select, promote, or reduce specific beneficial detrimental microorganisms. Overall, our highlight intricate interplay between amendments, communities, nutrient dynamics, suggesting particularly DMPFA, be pivotal bolstering agricultural sustainability optimizing utilization.
