Coelacanth assembly and gene annotation


This is the preliminary display of the Coelacanth (Latimeria chalumnae) genome produced by the Broad Institute. Illumina techology was used to produced this high quality draft. The whole genome shotgun data was assembled with Allpaths. The genome is 2.9gb in length;,composed of 291,828 contigs with an N50 value of 12.6kb and 22,818 scaffolds with an N50 value of 765kb.

The genome assembly represented here corresponds to GenBank Assembly ID GCA_000225785.1

Gene annotation

The Ensembl genome annotation pipeline was used to identify genes. Models built from Coelacanth proteins and cDNAs have been given priority over predictions from other vertebrate species. 6,671 transcript models made from paired end Illumina RNA-Seq were added into the gene set where they added a novel model or splice variant. RNA-Seq data was also used to add UTR to non species specific models. The total gene set contains 19,697 protein coding genes with a further 2,894 ncRNAs and 141 pseudogenes.
