Antarctic Notothenioids fish genomes project
The Notothenioids are a group of Percomorph fish and constitute one of the best characterized marine radiations. Notothenioids consist of over 130 species, and are the dominant fish group inhabiting Southern Ocean waters. Diversification events are linked to the formation of the Antarctic Circumpolar Current, which led to a drop of the water temperature. Notothenioids are cold water specialists which have developed Antifreeze glycoproteins to avoid freezing. Additionally, derived species of the Channichthyidae or icefish are lacking functional erythrocytes, making them the only vertebrate without blood.
At the Sanger Institute we are generating genome assemblies for 25 species across the Notothenioid radiation. We are generating 1 reference chromosome assigned assembly for Cottoperca gobio (channel bull blenny), and 4 draft reference assemblies for species Trematomus bernachii, Harpagifer antarcticus, Gymnodraco acuticeps, and Pseudochaenichtys georgianus. Also, we are generating 10X Chromium and Illumina HiSeq assemblies for 20 other species. As part of the project we are also generating transcriptome data for 16 Notothenioid species.
