Description

For GC-MS analysis, plant material was extracted as following: 50 mg of frozen material was crushed and extracted with 700 uL of pre-cooled methanol (-20oC). Were added 60 uL of adonitol (0.2 mg mL-1, internal standard), with the mixture being centrifuged (10 min at 11000 g) and the supernatant transferred to glasses tubes to add chloroform (375 uL at -20oC) and ultrapure water (750 uL at 4oC), with the polar and non-polar phases being collected separately. The non-polar phase was derivatized with 50 uL of pyridine and 50 uL of BSTFA (N,O-bis-(trimethylsilyl)-trifluoroacetamide) for 1 h at 70oC; 5 uL of tridecanoic acid (2 mg mL-1) was used as internal standard. The non-polar phase was analyzed by GC-MS equipped with an HP5-MS capillary column (30 m, 0.25 mm, 0.25 um). An initial column temperature was adjusted to 100oC for 5 min, and increasing at a rate of 5oC min-1 to a final temperature of 320oC, with a total run time of 49 min. 1 uL of injection volume with helium as a carrier gas. In both analyses a blank was injected in each 15 samples. [doi:10.25345/C5CV4C29V] [dataset license: CC0 1.0 Universal (CC0 1.0)]

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.
