Description
Fungal lipo-chitooligosaccharides (LCOs) are primarily defined as the molecules that mediate the establishment of symbiotic relationships between fungi and plants. However, recent studies have demonstrated that these polymers have distinct effects in the growth and development of fungi with diverse lifestyles, thus prompting new research efforts focused in understanding the emerging roles that these molecules have on fungi. In this study, we employed liquid chromatography coupled to high resolution tandem mass spectrometry to analyze global proteome changes of the ectomycorrhiza forming-fungi Laccaria bicolor when grown in the presence of exogenous sulfated and non-sulfated LCOs (sLCOs or nsLCOs, respectively), as well as the chitooligomers, chitotetraose (CO4) and chitooactose (CO8) 21-days post-induction. Physiological observations in LCOs and COs-treated samples highlighted a state of repressed growth when compared to controls. Quantitative proteomics analysis supported these observations by revealing substantial abundance alterations of proteins involved in controlling different aspects of polarized growth in L. bicolor.

Click here to queue conversion of this dataset's submitted spectrum files
to open formats (e.g. mzML). This process may take some time.
When complete, the converted files will be available in the "ccms_peak"
subdirectory of the dataset's FTP space (accessible via the "FTP Download"
link to the right).
Number of distinct conditions across all analyses (original submission and reanalyses)
associated with this dataset.
Distinct condition labels are counted across all files submitted in the "Metadata" category
having a "Condition" column in this dataset.
"N/A" means no results of this type were submitted.
Number of distinct biological replicates across all analyses (original submission and reanalyses)
associated with this dataset.
Distinct replicate labels are counted across all files submitted in the "Metadata" category
having a "BioReplicate" or "Replicate" column in this dataset.
"N/A" means no results of this type were submitted.
Number of distinct technical replicates across all analyses (original submission and reanalyses)
associated with this dataset.
The technical replicate count is defined as the maximum number of times any one distinct
combination of condition and biological replicate was analyzed across all files submitted in the
"Metadata" category. In the case of fractionated experiments, only the first fraction is
considered.
"N/A" means no results of this type were submitted.
Originally identified proteins that were automatically
remapped by MassIVE to proteins in the
SwissProt
human reference database.
"N/A" means no results of this type were submitted.
Number of distinct protein accessions reported across all analyses (original submission and
reanalyses) associated with this dataset.
"N/A" means no results of this type were submitted.
Number of distinct unmodified peptide sequences reported across all analyses (original
submission and reanalyses) associated with this dataset.
"N/A" means no results of this type were submitted.
Number of distinct peptide sequences (including modified variants or peptidoforms) reported
across all analyses (original submission and reanalyses) associated with this dataset.
"N/A" means no results of this type were submitted.
Total number of peptide-spectrum matches (i.e. spectrum identifications) reported across all
analyses (original submission and reanalyses) associated with this dataset.
"N/A" means no results of this type were submitted.
Number of distinct proteins quantified across all analyses (original submission and reanalyses)
associated with this dataset.
Distinct protein accessions are counted across all files submitted in the "Statistical Analysis
of Quantified Analytes" category having a "Protein" column in this dataset.
"N/A" means no results of this type were submitted.
Number of distinct proteins found to be differentially abundant in at least one comparison
across all analyses (original submission and reanalyses) associated with this dataset.
A protein is differentially abundant if its change in abundance across conditions is found
to be statistically significant with an adjusted p-value <= 0.05 and lists no issues associated
with statistical tests for differential abundance.
Distinct protein accessions are counted across all files submitted in the "Statistical Analysis
of Quantified Analytes" category having a "Protein" column in this dataset.
"N/A" means no results of this type were submitted.
This dataset may not contain all raw spectra data as originally deposited in PRIDE.
It has been imported to MassIVE for reanalysis purposes, so its spectra data here may
consist solely of processed peak lists suitable for reanalysis with most software.
