Crop Metabolome Web v1.0

Is an integrated platform for crop metabolome databases and analysis tools that is dedicated to metabolic profiling, metabolite identification, referencing standards, and repository and dissemination of crop metabolomics data. It currently contains three functional components: 1) metabolite reference libraries (MS/MS spectral tag [MS2T] libraries) for major crops (currently six available) and the associated tool 'MS2TBlast' to annotate crop samples; 2) a repository for dissemination of curated crop metabolomics data; 3) analytical tools 'CompoundLibBlast', 'FlavoBLAST', 'CropMetaDiscover', and 'PesticiSCAN', for crops metabolite profiling and discovery, and pesticidal residue detection for toxicity evaluation.

Database components:

  • CropMetaDB: Repository of raw metabolomics data for different crops.
  • MS2T libraries: Metabolite reference libraries for each of different crops.
  • Agrochemical spectral library: the spectral reference library generated for pesticides in US EPA Pesticide Ecotoxicity Database and EU Pesticides Database.

Analytical tools:

  • MS2TBlast: Searching MS2T libraries for identification of metabolite peaks in acquired crop samples.
  • CompoundLibBlast: Searching bioactive compound reference libraries to identify a metabolite by matching MS/MS spectra.
  • FlavoBLAST: Detecting flavonoid derivatives by matching in-source fragment ions of a flavonoid motif library.
  • CropMetaDiscover: Integrated pipeline for annotation of crop sample MS spectra using MS2T libraries.
  • PesticiSCAN: Detection of pesticide residues in crop samples by searching agrochemical spectral libraries for matching MS/MS spectra.
