Pervasive associations between dark septate endophytic fungi with tree root and soil microbiomes across Europe

Abstract Trees interact with a multitude of microbes through their roots and root symbionts such as mycorrhizal fungi endophytes. Here, we explore the role fungal predictors soil root-associated microbiomes widespread broad-leaved trees across European latitudinal gradient. Our results suggest that, alongside factors climate, soil, vegetation properties, colonization by ectomycorrhizal, arbuscular mycorrhizal, dark septate endophytic also shapes tree-associated microbiomes. Notably, structure our sites is more strongly consistently associated endophyte than many abiotic factors. Root endophytes has consistent negative association relative abundance diversity nutrient cycling genes. study not only indicates that root-symbiotic interactions are an important factor structuring communities functions in forest ecosystems, but hitherto less studied likely to be central players these interactions.

Advances in the Role of Dark Septate Endophytes in the Plant Resistance to Abiotic and Biotic Stresses

Journal of Fungi, Год журнала: 2021, Номер 7(11), С. 939 - 939

Опубликована: Ноя. 4, 2021

Endophytic fungi have been studied in recent decades to understand how they interact with their hosts, the types of relationships establish, and potential effects this interaction. Dark septate endophytes (DSE) are isolated from healthy plants form melanised structures roots, including inter- intracellular hyphae microsclerotia, causing low host specificity covering a wide geographic range. Many studies revealed beneficial between DSE such as enhanced plant growth, nutrient uptake, resistance biotic abiotic stress. Furthermore, decades, ability mitigate negative crop diseases, thereby highlighting biocontrol agents diseases (BCAs). Given importance these nature, article is review role BCAs. The findings increasing numbers on hosts also discussed enable use tool for integrated management pests.

Microbe‐dependent and independent nitrogen and phosphate acquisition and regulation in plants

New Phytologist, Год журнала: 2023, Номер 242(4), С. 1507 - 1522

Опубликована: Сен. 15, 2023

Summary Nitrogen (N) and phosphorus (P) are the most important macronutrients required for plant growth development. To cope with limited uneven distribution of N P in complicated soil environments, plants have evolved intricate molecular strategies to improve nutrient acquisition that involve adaptive root development, production exudates, assistance microbes. Recently, great advances been made understanding regulation uptake utilization how balance direct nutrients from beneficial microbes such as arbuscular mycorrhiza. Here, we summarize major these areas highlight responses changes availability external environment through local systemic signals.

Combined inoculation with dark septate endophytes and arbuscular mycorrhizal fungi: synergistic or competitive growth effects on maize?

BMC Plant Biology, Год журнала: 2021, Номер 21(1)

Опубликована: Окт. 29, 2021

Effects on maize were assessed of dual inoculation with arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE) isolated from other plant species.Suspensions DSE Stipa krylovii prepared at different densities (2, 4, 8 × 105 CFU mL- 1) inoculated separately (AMF or DSE) together + DSE), to explore their effects growth.Inoculation AMF medium high combined increased above-ground growth altered root morphology. Differences in attributable differences density, negative responsiveness low density. promoted more than the density development AMF. Combined might lead synergistic competitive densities.AMF co-colonized roots they had positive host plants depending These findings indicate optimum growth-promoting combination provide a foundation for further exploration potentially mechanisms between physiological ecological plants.

Advances in endophytic fungi research: a data analysis of 25 years of achievements and challenges

Research on fungal endophytes has demonstrated the ability to improve crop performance and protect host plants against diverse biotic abiotic stresses. Yet, despite exponential growth of this topic, a whole outline reflect relevance extent each study type is missing. Hence, we performed an analysis all available literature expose characteristics limitations research field. Our results suggested that, overall, there still tendency most known models in plant-fungal-stress combinations (ascomycetous fungi, grasses, stress). Fungal dicot or stress, though promising, are quite unexplored. All these data could lead future studies assess less considered factors that might help discern beneficial effects with more accuracy.

Phosphorus-Solubilizing Capacity of Mortierella Species Isolated from Rhizosphere Soil of a Poplar Plantation

Microorganisms, Год журнала: 2022, Номер 10(12), С. 2361 - 2361

Опубликована: Ноя. 29, 2022

Phosphorus is one of the main nutrients necessary for plant growth and development. Phosphorus-dissolving microorganisms may convert insoluble phosphorus in soil into available that plants can easily absorb utilize. In this study, four phosphorus-solubilizing fungi (L3, L4, L5, L12) were isolated from rhizosphere a poplar plantation Dongtai, Jiangsu Province, China. Phylogenetic analysis based on internal transcribed spacer (ITS) large subunit (LSU) ribosomal DNA sequences showed ITS 28S isolates most similar to those Mortierella. Morphological observation colonies grew concentric circles produced spores under different culture conditions. These results further microscopic observations these belonged genus Pikovskaya (PKO) medium, which tricalcium phosphate was sole source, used screen strain L4 with best effect study. When carbon source glucose, nitrogen ammonium chloride, pH 5, content highest. By exploring possible mechanism release by fungi, it found produces several organic acids, such as oxalic acid, lactic acetic succinic tartaric malic citric acid. At 24 h, alkaline phosphatase acid activities reached 154.72 mol/(L·h) 120.99 mol/(L·h), respectively.
