Cross-kingdom synthetic microbiota supports tomato suppression of Fusarium wilt disease

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Дек. 22, 2022

Abstract The role of rhizosphere microbiota in the resistance tomato plant against soil-borne Fusarium wilt disease (FWD) remains unclear. Here, we showed that FWD incidence was significantly negatively correlated with diversity both bacterial and fungal communities. Using microbiological culturomic approach, selected 205 unique strains to construct different synthetic communities (SynComs), which were inoculated into germ-free seedlings, their roles suppressing monitored using omics approach. Cross-kingdom (fungi bacteria) SynComs most effective than those Fungal or Bacterial alone. This effect underpinned by a combination molecular mechanisms related immunity microbial interactions contributed study provides new insight dynamics pathogen suppression host interactions. Also, formulation manipulation for functional complementation constitute beneficial strategy controlling disease.

The widespread use of biofertilizers, rather than chemical fertilizers, is significantly more likely to accomplish sustainable agriculture production globally. Plant growth-promoting rhizobacteria (PGPR) are chemical-free alternatives conventional crop protection in agriculture. Pseudomonas spp. unique among the PGPR genera terms root colonization, nitrogen fixation, exopolysaccharides, siderophores, hydrogen cyanide (HCN), and phytohormones, solubilization phosphorus, potassium, zinc, biofilm formation, antioxidant activities, stress adaptation abilities, positive interactions with other microbial communities. They also aid plant development by promoting biotic abiotic tolerance, as well supporting host nutrition. regarded an environmentally acceptable alternative harmful fertilizers because its active actions. However, achieve this goal, workers must first get a complete understanding numerous processes used Pseudomonas, allowing them fully exploit bacteria potential future. Therefore, present review has been undertaken discuss fundamental promote reduce environmental stresses. In addition, we described some reported Pseudomonas-based biofertilizers worldwide presence genes genome different strains understand mechanism mediated growth promotion at molecular level.

Acidification suppresses the natural capacity of soil microbiome to fight pathogenic Fusarium infections

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Авг. 22, 2023

Soil-borne pathogens pose a major threat to food production worldwide, particularly under global change and with growing populations. Yet, we still know very little about how the soil microbiome regulates abundance of their impact on plant health. Here combined field surveys experiments investigate relationships properties structure function contrasting health outcomes. We find that acidification largely impacts bacterial communities reduces capacity soils combat fungal pathogens. In vitro assays microbiomes from acidified further highlight declined ability suppress Fusarium, globally important pathogen. Similarly, when inoculate healthy plants an microbiome, show greatly reduced prevent pathogen invasion. Finally, metagenome sequencing untargeted metabolomics reveals down regulation genes associated synthesis sulfur compounds reduction key traits related metabolism in acidic soils. Our findings suggest changes disruption specific microbial processes induced by can play critical role for

Inoculated microbial consortia perform better than single strains in living soil: A meta-analysis

Applied Soil Ecology, Год журнала: 2023, Номер 190, С. 105011 - 105011

Опубликована: Июнь 16, 2023

Microbial consortium inoculation has been proposed as a natural-based strategy to safeguard multiple ecosystem services. Still, its observed effects and comparisons single-species have yet be systematically quantified. In this global meta-analysis of 51 live-soil studies (carefully selected from pool 2149 studies), we compared the impact (mean variability) inoculations on biofertilization bioremediation. Our results showed that both increased plant growth by 29 % 48 %, respectively, pollution remediation 80 with non-inoculated treatments. We revealed diversity inoculants synergistic effect between frequently used inoculums (e.g., Bacillus Pseudomonas) contributed effectiveness inoculation. Despite reduction in efficacy field settings greenhouse results, had more significant overall advantage under various conditions. recommend increasing original soil organic matter, available N, P content regulating pH 6–7 achieve better effect. Overall, these findings support use microbial consortia for improved bioremediation living suggest perspectives constructing inoculating beneficial consortia.

Crop rotation and native microbiome inoculation restore soil capacity to suppress a root disease

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Дек. 8, 2023

It is widely known that some soils have strong levels of disease suppression and prevent the establishment pathogens in rhizosphere plants. However, what are better suppressing disease, how management can help us to boost remain unclear. Here, we used field, greenhouse laboratory experiments investigate effect (monocropping rotation) on capacity microbiomes peanut root rot disease. Compared with crop rotations, monocropping resulted microbial assemblies were less effective diseases. Further, depletion key taxa monocropping, which at a disadvantage competition for limited exudates resources, reduced protect plants against pathogen invasion. supplementation depleted strains restored resistance pathogen. Taken together, our findings highlight role native soil microbes fighting supporting plant health, indicate potential using inocula regenerate natural fight

A promising, sustainable way to enhance plant health and productivity is by leveraging beneficial microbes. Beneficial microbes are natural soil residents with proven benefits for performance health. When applied in agriculture improve crop yield performance, these commonly referred as bioinoculants. Yet, despite their promising properties, bioinoculant efficacy can vary dramatically the field, hampering applicability. Invasion of rhizosphere microbiome a critical determinant success. complex phenomenon that shaped interactions local, resident host plant. Here, we explore all dimensions cross-cutting ecological theory molecular biology microbial invasion rhizosphere.
