Data from: High quality whole genome sequence of an abundant Holarctic odontocete, the harbour porpoise (Phocoena phocoena)

The harbour porpoise (Phocoena phocoena) is a highly mobile cetacean found
across the Northern hemisphere. It occurs in coastal waters and inhabits
basins that vary broadly in salinity, temperature, and food availability.
These diverse habitats could drive subtle differentiation among
populations, but examination of this would be best conducted with a robust
reference genome. Here we report the first harbour porpoise genome,
assembled de novo from an individual originating in the Kattegat Sea
(Sweden). The genome is one of the most complete cetacean genomes
currently available, with a total size of 2.39 Gb and 50% of the total
length found in just 34 scaffolds. Using just 122 of the longest
scaffolds, we were able to show high levels of synteny with the genome of
the domestic cattle (Bos taurus). Our draft annotation comprises 22,154
predicted genes, which we further annotated through matches to the NCBI
nucleotide database, GO categorization, and motif prediction. Within the
predicted genes we have confirmed the presence of >20 genes or gene
families that have been associated with adaptive evolution in other
cetaceans. Overall, this genome assembly and draft annotation represent a
crucial addition to the genomic resources currently available for the
study of porpoises and Phocoenidae evolution, phylogeny, and conservation.
