Description

Seeds are crucial for plant reproduction, dispersal, and agriculture. Seed quality and vigour greatly impact crop production, referring to their ability to germinate rapidly and uniformly under varying environmental conditions, producing healthy seedlings that can withstand biotic and abiotic stress accentuated by global climate change. During germination, seeds release exudates, complex mixtures of organic and inorganic molecules, into the micro-environment surrounding them, known as the spermosphere. These exudates play a pivotal role in seedling development and overall plant fitness by influencing microbial selection, growth, and interactions in the spermosphere, ultimately shaping the plant's microbiome. To understand the composition and functional properties of germinating seed exudates, we conducted our study using different common bean (Phaseolus vulgaris L.) genotypes. Seeds were harvested in the year 2020 from eight different common bean genotypes (French commercial cultivars of Phaseolus vulgaris) cultivated in two different locations from the FNAMS field experimental stations: Gers in South-west of France (43.956991, 0.392127) and Maine et Loire (47.470532, -0.394526) in the Loire Valley. The common bean genotypes namely, VEZ, CON, CAP, FAC, FLA, LIN, DEE and VAN were chosen to represent the highest diversity among breeding programmes and qualitative seed traits in France by the seed company Vilmorin-Mikado SAS (Limagrain group). One seed lot corresponds to seeds from one genotype produced in one location. Independent biological replicates were conducted for each seed lot. Thus, 48 samples were analyzed, corresponding to three replicates of eight genotypes produced in two locations. Spermosphere collection of germinating seeds involved the imbibition of 30 seeds for each sample at four distinct time intervals: 2, 8, 16, and 24 hours. The collected spermosphere, consisting of the water surrounding germinating seeds, was gathered for each time interval and subsequently pooled. Subsequently we investigated the diversity of metabolites of each pooled spermosphere using untargetted metabolomic (LC-MS/MS) analysis.

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.
