Project description:Cell lysates of Fusarium sp. DS 682, a saprotrophic fungus, were prepared from fungal biomass grown on PDA agar without M9 and micronutrients. Fungus was exposed to minerals, 100 uL of 50% (w/v) natural kaolinite solution. Three fungal plate collections for each growth condition, with (+ mineral) and without mineral (- mineral), were grown for 14 days on PDA (incubated at 28 C) and harvested after 15 days. Extracted hyphae (500 mg) was prepared using the MPLEx protocol. A nanoACQUITY ultra performance liquid chromatography (LC) with a 2DLC system was used for separation of protein digests. Eluted peptides from the C18 column were analyzed using a Q-Exactive Plus Orbitrap MS for high resolution MS and high-energy collision-induced dissociation tandem MS by electrospray ionization for subsequent quantitative proteomic analysis. Data was searched with MaxQuant. Additional post-processed results and metadata can be accessed at https://doi.org/10.25584/KSOmicsFspDS682/1766303
Project description:Fungal effectors play important roles in inciting disease development on host plants. We identified an effector (Secreted in Xylem4, SIX4) in an Arabidopsis infecting isolate (Fo5176) of the root-infecting fungal pathogen Fusarium oxysporum and demonstrated this effector is required for full virulence. To explore the role of Fo5176_SIX4 we use whole transcriptome profiling of root tissues from plants overexpressing this effector (35sSIX4) versus wild-type (Col-0) plants after F. oxysporum infection. We grew both WT and 35sSIX4 plants for four weeks in soil. After four weeks the plants were infected with Fusarium oxyporum isolate Fo5176, trays covered with a plastic dome and incubated at 28C. There were four independent replicates of each treatment and each replicate contained root tissue from 20 plants. Each replicate (8 in total) was harvested 4 days post inoculation and the resulting RNA was used for hybridization to an Affymetrix ATH1 chip.
Project description:Tandem Mass Tag (TMT)-based quantitative proteomic analysis of tomato soil borne pathogen Fusarium oxysporum f. sp. radicis-lycopersici growth, and metabolism when treated with plant natural volatile organic compounds linalool. The Forl strain was cultured on PDA supplied with 0.8 mL/L linalool for 6 days at 25°C. The fungal strain on PDA supplied with only 0.1% Tween80 was cultured as the control. Three biological replicates were established for each treatment.

Project description:To evaluate the effect of the dual CXCR1/CXCR2 inhibitor SX-682 on tumor growth, BrafV600E/PTEN-/- mice were fed with either SX-682 chow (0.756 g/kg of SX-682, Syntrix Pharmaceuticals, Inc) or control chow for RNA-seq analysis.
Project description:The novel fungal strain, Fusarium sp. strain DS 682, was isolated from the rhizosphere of the perennial grass, Bouteloua gracilis, at the Konza Prairie Biological Station in Kansas. This fungal strain is common across North American grasslands and is resilient to environmental fluctuations. The draft genome is estimated to be 97.2% complete.
Project description:The plant fungal pathogen Fusarium graminearum which has part of its life cycle in the soil generally comes in contact with bacteria. Therefore the fungus was used as fungal model to test fungal responses to bacterial presence and ascertain the presence of an innate immune system in fungi through a transcriptomics study. Bacterial presence was established by exposing young fungal cultures to the well characterised MAMPs (Microbe Associated Molecular Pattern) such as Flagellin (FLG), Lipooligosacharides (LOS) and Peptidoglycans (PGN) and water was used as the control. The results showed that the fungus reacts to the presence of MAMPs within hours and that the 3 MAMPs up-regulated a set of common genes. These significantly up-regulated common genes can be classified into categories such as energy generation, amino acid metabolism, iron uptake, secondary metabolism and transporters related to secondary metabolism. Analysis of the transcriptional reponse from FLG showed that the MAMP which was obtained comercially was blended with sucrose and this was later confirmed by the commercial provider.
