Abstract:
The harbour porpoise (Phocoena phocoena) is a highly mobile cetacean found
in waters across the Northern hemisphere. It occurs in coastal water and
inhabits water basins that vary broadly in salinity, temperature, and food
availability. These diverse habitats could drive differentiation among
populations. Here we report the first harbour porpoise genome, assembled de
novo from a Swedish Kattegat individual. The genome is one of the most
complete cetacean genomes currently available, with a total size of 2.7 Gb
and 50% of the total length found in just 34 scaffolds. Using the largest
122 scaffolds, we were able to validate a high level of homology to the
chromosome-level genome assembly of the closest related species for which
such resource was available, the domestic cattle (Bos taurus). The draft
annotation comprises 22,154 predicted gene models, which we further
annotated through matches to the NCBI nucleotide database, GO
categorization, and motif prediction. To infer the adaptive abilities of
this species, as well as their population history, we performed a Bayesian
skyline analysis, and produced results that are concordant with the
demographic history of this species, including expansion and fragmentation
events. Overall, this genome assembly, together with the draft annotation,
represents a crucial addition to the limited genetic markers currently
available for the study of porpoises and Phocoenidae conservation,
phylogeny, and evolution.
Kind regards,
Marijke Autenrieth
