For potato production, continuous cropping (CC) could lead to autotoxicity buildup and microflora imbalance in the field soil, which may result failure of crops reduction yield. In this study, non-targeted metabolomics (via liquid chromatography with tandem mass spectrometry (LC-MS/MS)) combined metagenomic profiling high-throughput amplicon sequencing) were used evaluate correlations between root exudates communities bacteria fungi around plants illustrate impacts CC. Potato grown soil collected from fields various CC years (0, 1, 4, 7 years). Metabolomic analysis showed that contents types potential autotoxins increased significantly CC4 CC7 (i.e., soils 4 CC). The differentially expressed metabolites mainly produced via alpha-linolenic acid metabolism plant groups CC0 CC1 no or 1 year became dominated by styrene degradation, biosynthesis siderophore group non-ribosomal peptides, phenylpropanoid biosynthesis, secondary metabolites.

Published: July 8, 2024

Abstract Background The ginseng endophyte Paenibacillus polymyxa Pp-7250 (Pp-7250) has multifaceted roles such as preventing diseases, promoting growth, increasing ginsenoside accumulation, and degrading pesticide residues, however, these effects still have room for improvements. Composite fungicides are an effective means to improve the biocontrol effect of fungicides, but in combination with its symbiotic bacteria on needs be further investigated, mechanism action not been elucidated.

Plant–microorganism–soil interaction under long-term low-dose ionizing radiation

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 14

Published: Jan. 11, 2024

As the environmental nuclear radiation pollution caused by nuclear-contaminated water discharge and other factors intensifies, more plant–microorganism–soil systems will be under long-term low-dose ionizing (LLR). However, regulatory mechanisms of system LLR are still unclear. In this study, we study a that has been stably exposed to for 10 years investigate response based on decay absorbed dose rate with distance. The results show affects carbon nitrogen migration process between through “symbiotic microbial effect.” increase in intensity led significant relative abundance symbiotic fungi, such as Ectomycorrhizal fungi Rhizobiales, which is accompanied soil lignin peroxidase (LiP) activity, C/N ratio, C%. Meanwhile, enhanced causes adaptive changes plant functional traits. This demonstrates effect” an important terrestrial ecosystems LLR.

Analysis of Microbial Diversity and Community Structure of Rhizosphere Soil of Three Astragalus Species Grown in Special High-Cold Environment of Northwestern Yunnan, China

Microorganisms, Journal Year: 2024, Volume and Issue: 12(3), P. 539 - 539

Published: March 7, 2024

Astragalus is a medicinal plant with obvious rhizosphere effects. At present, there are many plants high application value but low recognition and resource reserves in the northwestern area of Yunnan province, China. In this study, metagenomics was used to analyze microbial diversity community structure soil A. forrestii, acaulis, ernestii grown special high-cold environment Yunnan, China, at different altitudes ranging from 3225 4353 m. These microbes were taxonomically annotated obtain 24 phyla 501 genera for 30 504 as well 39 533 ernestii. Overall, dominant bacterial included Proteobacteria, Actinobacteria, Acidobacteria, while fungal ones Ascomycota Basidiomycota. genus level, Bradyrhizobium, Afipia, Paraburkholderia most prevalent bacteria, Hyaloscypha, Pseudogymnoascus, Russula genera. Some them considered biocontrol that could sustain growth health host plants. Redundancy analysis revealed pH, TN, SOM had significant impact on structures (p < 0.05).

The cultivation of tartary buckwheat serves dual roles, offering health benefits and nutritional advantages. Nonetheless, its is challenged by issues such as soil degradation climatic drought. Plant growth-promoting (PGP) microorganisms hold promise for addressing these challenges. In this study, we investigated the effects Serendipita indica inoculation on root-associated microbial communities buckwheat. Additionally, used S. to construct synthetic consortia, their role in promoting growth enhancing drought resistance was evaluated. This study found that colonization promoted enrichment beneficial Actinobacteriota, Sphingomonas , Mortierella while reducing relative abundance pathogenic genera including Cladosporium Alternaria Acremonium . addition, consortia significantly photosynthesis biomass accumulation buckwheat, also improving structure fertility. Under conditions, introducing groups markedly boosted root development, lowered density stomata rate transpiration leaves, decreased H 2 O Malondialdehyde (MDA) levels, thus greatly buckwheat’s conclusion, our findings demonstrated constructed with can promote enhance resistance. However, specific molecular mechanisms underlying require further investigation future studies. These will provide important theoretical support development novel fertilizers.

Transplanting is important for obtaining and maintaining excellent germplasm of cultivated plants. During plant transplantation, the endophytic microbial community regularly reorganizes, which may be crucial rejuvenation. Angelica sinensis , a widely used medicinal edible plant, relies on transplanting its exceptional quality. To explore microecological recombination A. during process “alpine seedling–cellar planting–dam cultivation”, this study analyzed shifts in soil communities across three stages Min County, Gansu Province, China. High-throughput sequencing revealed significant changes, with 82.27% to 84.65% bacteria 93.19% 93.49% fungi species altering transplanted . Main findings indicate that Mortierellomycota, Actinobacteriota, Myxococcota were dominant cellar planting root rhizosphere soil, contrasting Firmicutes predominance alpine dam areas. Notably, potentially pathogenic endophytes like Fusarium Xanthomonas decreased post-alpine seedling planting, favoring healthier environment. Cellar exhibited rich accumulation psychrophilic flora, including Tetracladium Pseudomonas Flavobacterium alongside unique dominance Mortierella fungi. Microbial co-occurrence network analysis highlighted as pivotal, suggesting importance interactions. In conclusion, significantly reshaped ’s showing more pronounced than bacteria.
