Proteomic analysis of mycelial exudate of Ustilaginoidea virens

ABSTRACT: Rice false smut (RFS) is a kind of fungal disease transforming panicles and spikelets into greenish spore balls, caused by Ustilaginoidea virens. During artificial cultivation process, macroscopic exudates could be observed, which is a common feature in many kinds of fungi. We characterized the proteome of exudate associated with this plant pathogen. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was used to identify proteins in the pathogen exudate. A total of 685 proteins comprising 3,949 peptides were identified from the exudate. This study regarded the biological characteristics of U. virens as an entry point. By studying the protein components of the exudates of U. virens, it is helpful to better understand the occurrence and pathogenic mechanism of pathogen and provide a theoretical basis for the control of RFS.

Rice false smut (RFS) disease, which is caused by Ustilaginoidea virens, has been widespread all over the world in recent years, causing irreversible losses. Under artificial culture conditions, exudates will appear on colonies of U. virens during the growth of the hyphae. Exudation of droplets is a common feature in many fungi, but the functions of exudates are undetermined. As the executors of life functions, proteins can intuitively reflect the functions of exudates. Shotgun pro ...[more]

Temporal gene expression profiling of myeloid cells during the peritoneal foreign body response

Project description:This study dermined the temporal gene expression profile of myeloid subpopulations recruited to the peritoneal cavity to encapsulate implanted foreign material. Sterile foreign objects were inserted into the peritoneal cavities of MacGreen mice (in which the Csf1r promoter directs myeloid-specific EGFP expression). At various time-points post-surgery (days 2, 4, 7, 14), mice were euthanased, and peritoneal exudate cells removed by lavage. Peritoneal exudate cells from MacGreen mice that had not received implants were used as controls (day 0; 'unstimulated'). Free-floating objects encapsulated with tissue were removed from the peritoneal cavities of different mice at days 7, 14, 21, 28 days, and single cell suspensions obtained by collagenase digestion. Single-cell suspensions from peritoneal exudate or tissue capsules were separated on the basis of size/granularity and EGFP fluorescence using FacsVantage SE Diva. Total RNA was extracted from FACS-sorted EGFP-hi cells.

Proteomics and metabolomics profiling of pork exudate reveals meat spoilage during storage

Project description:Previous studies have evaluated pork quality by omics methods. However, proteomics coupled with metabolomics to investigate pork freshness by using pork exudates has not been reported. This study determined the changes in profiles of peptides and metabolites in exudates from pork stored at different temperatures (25, 10, 4, and -2 ℃). Multivariate statistical analysis revealed similar changes in profiles in exudates collected from pork stored at -2 and 4 ℃, and additional changes following storage at higher temperatures. We identified peptides from 7 proteins and 30 metabolites differing in abundance between fresh and spoiled pork. Significant correlations be-tween pork quality and most of the peptides from these 7 proteins and 30 metabolites were found. The present study provides insight into changes in peptide and metabolite profiles of exudates from pork during storage at different temperatures and our analysis suggest that such changes can be used as markers for pork spoilage.

G3P triggered changes in systemic transcriptome

Project description:Goal of this study was to determine changes in transcription profile in mock versus G3P treated plants. Arabidopsis (Col-0 ecotype) plants were infiltrated with petiole exudate, with or without G3P, and distal leaves were sampled 24 h post treatments. Keywords: Glycerol-3-Phosphate, Exudate, Salicylic acid, Arabidopsis, Systemic Acquired Resistance, Defense 3 mock-treated and 3 G3P-treated biological replicates were analyzed (one array each) Total RNA was isolated from four-week-old plants using TRIZOL method. The experiment was carried out in triplicate and a separate group of plants was used for each set. RNA was processed and hybridized to the Affymetric Arabidopsis ATH1 genome array GeneChip following the manufacturers instructions (http://www.affymetrix.com/Auth/ support/downloads/manuals/expression_analysis_technical_manual.pdf <http://www.affymetrix.com/Auth/%20support/downloads/manuals/expression_analysis_technical_manual.pdf> ). All probe sets on the Genechips were assigned hybridization signal above background using Affymetrix Expression Console Software v1.0 (http://www.affymetrix.com/Auth/support/downloads/manuals /expression_console_userguide.pdf <http://www.affymetrix.com/Auth/support/downloads/manuals%20/expression_console_userguide.pdf> ). Data was analyzed using the nonparametric Wilcoxen Rank Sum test. Fold changes are reported as ratios of medians. The P values were calculated individually for each probe set.

Genome-wide binding of STAT3 in peritoneal macrophages

Project description:To try to identify the mechanism of STAT3âs indirect action we have used a genomic approach to map the binding sites of STAT3 within the genome and also used RNA-seq technology to map the changes in RNA expression and transcript isoforms in response to IL-10. Examination of STAT3 binding by ChIP-seq in Unstimulated and IL-10 treated peritoneal exudate macrophages purified from mice. We sequenced anti-STAT3 ChIP-seq as well as corresponding control (Input) libraries

MicroRNAs in Pyrus stigma tissue and stigma exudates

Project description:In many plant species, flower stigma secretions are important in early stages of sexual reproduction. Previous chemical analysis and proteomic characterization of these exudates provided insights into their biological function. Nevertheless, the presence of nucleic acids in the stigma exudates has not been previously reported. Here we studied the stigma exudates of Pyrus communis, Pyrus pyrifolia and Pyrus syriaca, and showed them to harbor extracellular RNAs of various sizes. RNA sequencing revealed, for the first time, the presence of known Rosaceae mature micro-RNAs (miRs), also abundant in the stigma source tissue. Predicted targets of the exudate miRs in the Arabidopsis thaliana genome include genes involved in various biological processes. Several of these genes are pollen transcribed, suggesting possible involvement of exudate miRs in transcriptional regulation of the pollen. Moreover, extracellular miRs can potentially act across kingdoms and target genes of stigma interacting organisms/microorganisms, thus opening novel applicative avenues in HortSciences.

Proteomic analysis of exudate of Cercospora armoraciae from Armoracia rusticana

Project description:Cercospora armoraciae causes leaf spot disease on Armoracia rusticana. Exudation of droplets, when grown on PDA, distinguishes this fungi from other members of the genus Cercospora. The role this exudate plays in the virulence of this pathogen has not been elucidated. To explore this, we characterized the proteome of exudate associated with this plant pathogen. Nano-HPLC-MS/MS analysis was used to identify proteins in the pathogen exudate. A total of 576 proteins comprising 1,538 peptides, 1,524 unique peptide, were identified from the exudate.
