SalmoBase: an integrated molecular data resource for Salmonid species

Area of Science:

• Genomics
• Evolutionary Biology
• Bioinformatics

Background:

• Salmonids, encompassing ~70 species like salmon and trout, possess an autotetraploid genome due to a whole genome duplication event ~80 million years ago.
• Ongoing genomic rediploidization in salmonids offers a unique model for studying the evolutionary impacts of whole genome duplication.
• High-quality genome sequences for Atlantic salmon and rainbow trout are now available, driven by their scientific and economic importance.

Purpose of the Study:

• To introduce SalmoBase, a centralized resource for salmonid molecular data.
• To provide a framework with visualizations and analytical tools for studying salmonid genomics and evolution.

Main Methods:

• Development of SalmoBase as part of the ELIXIR.NO project.
• Integration of molecular resources for Atlantic salmon and rainbow trout.
• Data accessibility via BLAST, Genome Browser (GBrowse), Genetic Variation Browser (GVBrowse), and Gene Expression Browser (GEBrowse).

Main Results:

• SalmoBase offers integrated molecular resources for Atlantic salmon and rainbow trout.
• Users can access and analyze salmonid data through various bioinformatics tools within the database.

Conclusions:

• SalmoBase is the first database to integrate salmonid data, enabling comprehensive study within a unified framework.
• Future expansion will include additional Salmonidae genomes and comparative genomics tools, such as synteny browsers.
