Abstract The plant health status is determined by the interplay of plant-pathogen-microbiota in rhizosphere. Here, we investigate this tripartite system focusing on pathogen Fusarium oxysporum f. sp. lycopersici (FOL) and tomato plants as a model system. First, explore differences genotype resistance to FOL potentially associated with differential recruitment plant-protective rhizosphere taxa. Second, show production fusaric acid trigger systemic changes microbiota. Specifically, molecule have opposite effects disease-suppressive taxa resistant susceptible genotypes. Last, elucidate that induce root exudation direct specific Our study unravels mechanism mediating assembly disease suppression integrating physiological responses microbial-mediated mechanisms

Abstract Plant pathogens cause plant diseases that significantly decrease crop yields, posing a serious threat to global food security. While disease resistance has traditionally been understood as the trait determined by innate immune system and pathogen virulence system, recent research underscores pivotal role of microbiome in resistance. Plant-associated microbiomes confer protection against through direct inhibition, resource competition, activation responses. Agricultural practices such rotation, intercropping, disease-resistant breeding, biocontrol, organic farming modulate microbiomes, thereby influencing This review synthesizes latest advancements understanding intricate interactions among plants, pathogens, microbiomes. We emphasize need for in-depth mechanistic studies linking agricultural dynamics propose future directions leverage sustainable agriculture.

Volatile organic compounds (VOCs) released by plants can act as signaling molecules mediating ecological interactions. Therefore, the study of VOCs mediated intra- and interspecific interactions with downstream plant physiological responses is critical to advance our understanding mechanisms underlying information exchange in plants. Here, we investigated how plant-emitted affect performance an neighboring via induced shifts root exudate chemistry implications for root-associated microbiota recruitment. First, showed that emitted potato-onion stimulate growth adjacent tomato Then, demonstrated this positive effect on biomass was attributed rhizosphere microbiota. Specifically, found indirectly recruitment specific bacteria (e.g., Pseudomonas Bacillus spp.) rhizosphere. Second, identified validated compound dipropyl disulfide active molecule within blend communication. Third, occurs changes exudates caused exposure disulfide. Last, spp. enriched were shown have growth-promoting activities. Potato-onion VOCs—specifically disulfide—can induce plants, which results plant-beneficial Taken together, elucidated a new mechanism interaction resulting alterations beneficial outcomes performance.

Phytophthora cinnamomi causes significant root rot in hickory, leading to substantial yield losses. While Bacillus spp. are recognized as beneficial rhizosphere microorganisms, their application against hickory and impact on microbial communities remain under-investigated. This study demonstrated that velezensis TCS001 significantly inhibited P. ST402 growth vitro, achieved 71% efficacy disease management. Scanning electron microscopy (SEM) revealed fermentation filtrate induced mycelial deformities cinnamomi. An analysis of α β diversity indicated a bacterial community richness diversity, with minimal effects the fungal community. Moreover, altered microbiome co-occurrence network. The differential abundance suggests promotes recruitment microbes associated resistance, thereby suppressing development. These findings underscore influence presence pathogens, providing valuable data for future research development effective biocontrol strategies rot.

It is imperative to investigate the impact of irrigation on microorganisms inhabiting soil in greenhouses, as this understanding crucial for implementation effective water conservation strategies and optimal health sustenance greenhouse tomato production. To end, a tomato-cultivating experiment was conducted greenhouse, with control group receiving no planting or (W0), during years 2021 2022 Taiyuan region Shanxi Province, China. The incorporated three levels: W1 (50–70% field capacity), W2 (60–80% W3 (70–90% capacity). objective our study clarify effects different levels bacterial fungal community compositions functions, well yield use efficiencies, by analyzing changes structural characteristics potential functional composition bacteria fungi under levels. Our results showed that comparison treatment, treatment exhibited highest α-diversity, while its diversity lowest. r-strategy microbial demonstrated increased abundance treatment. relative common beneficial 0.32–1.70%, but decreased 0.09–3.75%. Among treatments, abundances Bacillus Plectosphaerella changed most. structure remained largely unchanged, saprotroph 14.72–23.28%. With increase volume, increased, though efficiency not greatest. did significantly reduce yield, it pathotroph groups fungi, which may stress resistance plants soil-borne diseases. findings serve valuable reference point prediction enhancement yields.

Background Rhizosphere soil microorganisms, as the second genome of plants, play an important role in formation secondary metabolites medicinal plants and are one key factors authenticity materials. Methods In this paper, rhizosphere soils Gentiana scabra Bunge from six producing areas Liaoning Province were taken research objects. Through high-throughput sequencing technology, with help PLS-DA RDA, impacts microorganisms environmental on quality G. explored depth. Results Alpha diversity shows that bacterial communities varies significantly, while regularity fungi is weak; beta samples different can be effectively grouped according to community structure. LDA effect differential species bacteria vary among areas. Indicator random forest analysis show Sphingomonas Subgroup_2 main indicator high-content group, which increase evenness microbial maintain or enhance diversity. The fungal relatively weak.
