Integration of multi-omics data of microbial species

Short description 

Many microbiome researchers seek to investigate the functional potential of microbial ecosystems with a holistic, multi-omics approach. Currently, interoperability between genomic, transcriptomic, and proteomic data for instance is a bottleneck. The workflow of this analysis that is being established by MULTI tackles such issues to facilitate future work for members of the community.

The first application and basis for the establishment of the workflow is the investigation of antimicrobial resistance in different Listeria monocytogenes strains by applying multi-omics data analysis. Three different L. monocytogenes strains were cultured on sub-lethal concentrations of biocides, their genomes sequenced, and transcriptomics and proteomics data collected. These data will provide insights into the functional responses of the bacteria to the biocide by analyzing pathways that differ in their gene expression or protein translation. Genome-scale metabolic reconstructions can be integrated with both transcriptomics and proteomics data, resulting in multi-omics data integration, which can provide insights into the different functional responses of microbial cells to an antimicrobial substance.

How you can contribute 

You are a … 

  • microbiologist with short and long read genomic sequences of bacterial isolates:
    Use the workflow to assemble circular genomes of your isolates, annotate genes and proteins, and create genome-scale metabolic reconstructions.
  • microbiologist with isolate genome sequences and transcriptomics and/or proteomics data:
    Use the workflow to analyze differential gene expression (transcriptomics), protein translation (proteomics), and integrate these data sets with the genomes using genome-scale metabolic reconstructions.
  • microbiologist with experience in transcriptomics or proteomics analyses:
    Check out the preliminary guidelines on data processing, analysis, and integration of genomics, transcriptomics, and proteomics data.
    Give suggestions and feedback on the workflow and useful additional features that could be implemented.
