Hagfish assembly and gene annotation

Assembly

The Eburgeri_3.2 assembly was submitted by Riken Center For Development Biology on 2017-10-24. The assembly is on the scaffold level, consisting of 10846 scaffolds. The total length is 2608383542 of which 1172995459 positions are gaps.

Gene annotation

Hagfish, are eel-shaped, slime-producing marine fish (occasionally called slime eels). They are the only known living animals that have a skull but no vertebral column, although hagfish do have rudimentary vertebrae. Along with lampreys, hagfish are jawless; they are the sister group to jawed vertebrates, and living hagfish remain similar to hagfish from around 300 million years ago.

The gene annotation of the hagfish was created via a combination of RNA-seq based annotation of nine adult tissues, three development stages and one artificially merged set of all reads. This was combined with protein-to-genome alignments of a subset of vertebrate proteins. Cut-off parameters for the alignments were relaxed to account for the distant nature of hagfish to most other vertebrates. Small ncRNAs were obtained using a combination of BLAST and Infernal/RNAfold. lincRNAs were generated via RNA-seq data where no evidence of protein homology or protein domains could be found in the transcript.

In accordance with the Fort Lauderdale Agreement , please check the publication status of the genome/assembly before publishing any genome-wide analyses using these data.
