GNPS - Tracking the degradation of fresh particulate organic matter in permeable riverbed sediments

Subscribe Comment Convert Spectra Add Reanalysis

Description

This project builds upon a DOE Subsurface Biogeochemical Research (SBR) project on the transport and metabolism of fresh, photosynthetically-derived (mainly periphyton) particulate organic matter (POM) in near-surface riverbed sediments at the PNNL SFA Hanford 300 Area study site. We propose to utilize a combination of Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) and polar metabolomics, together with metagenomic/transcriptomic sequencing to track, in a substrate-explicit manner, the degradation of fresh POM in Hanford 300 Area riverbed sediments. The overarching hypothesis behind our proposed research is that there will be detectable chemical and (meta)genomic responses to the input of fresh POM. Many previous studies have demonstrated distinct metabolic and bulk geochemical responses to fresh POM input, and a few studies have directly examined the uptake and degradation of POM in permeable marine sediments. In addition, our recent studies at the Hanford 300 Area indicate that in situ input of fresh POM (likely dominated by periphyton detritus) to the near-surface riverbed is an important driver of both microbial community composition and activity in the vicinity of the Hanford 300 Area. This research was performed under the Facilities Integrating Collaborations for User Science (FICUS) program (proposal:https://doi.org/10.46936/fics.proj.2021.60033/60000394) and used resources at the DOE Joint Genome Institute (https://ror.org/04xm1d337) and the Environmental Molecular Sciences Laboratory (https://ror.org/04rc0xn13), which are DOE Office of Science User Facilities operated under Contract Nos. DE-AC02-05CH11231 (JGI) and DE-AC05-76RL01830 (EMSL). [doi:10.25345/C5DB7W31X] [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.
