    • Characterization of mitochondrial mRNAs in codfish reveals unique features compared to mammals 

      Coucheron, Dag-Hugo; Nymark, Marianne; Breines, Ragna; Karlsen, Bård Ove; Andreassen, morten; Jørgensen, Tor Erik; Moum, Truls; Johansen, Steinar Daae (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Expression and processing of mitochondrial gene transcripts are fundamental to mitochondrial function, but information from early vertebrates like teleost fishes is essentially lacking. We have analyzed mitogenome sequences of ten codfishes (family Gadidae), and provide complete sequences from three new species (Saithe, Pollack and Blue whiting). Characterization of the mitochondrial mRNAs in Saithe ...

    • Complete mitochondrial genome sequences of the Arctic Ocean codfishes Arctogadus glacialis and Boreogadus saida reveal oriL and tRNA gene duplications 

      Breines, Ragna; Ursvik, Anita; Nymark, Marianne; Johansen, Steinar; Coucheron, Dag-Hugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-05-27)
      We have determined the complete mitochondrial genome sequences of the codWshes Arctogadus glacialis and Boreogadus saida (Order Gadiformes, Family Gadidae). The 16,644 bp and 16,745 bp mtDNAs, respectively, contain the same set of 37 structural genes found in all vertebrates analyzed so far. The gene organization is conserved compared to other Gadidae species, but with one notable exception. ...

      Jørgensen, Tor Erik; Karlsen, Bård Ove; Emblem, Åse; Breines, Ragna; Andreassen, morten; Rounge, Trine Ballestad; Nederbragt, Alexander Johan; Jakobsen, Kjetill Sigurd; Nymark, Marianne; Ursvik, anita; Coucheron, Dag H; Jakt, Lars Martin; Nordeide, Jarle Tryti; Moum, Truls Borg; Johansen, Steinar Daae (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-19)
      Objective:<br> The objective of this study was to analyse intraspecifc sequence variation of Atlantic cod mitochondrial DNA, based on a comprehensive collection of completely sequenced mitochondrial genomes. <br>Results:<br> We determined the complete mitochondrial DNA sequence of 124 cod specimens from the eastern and western part of the species’ distribution range in the North Atlantic Ocean. ...

    • A mitogenomic approach to the taxonomy of pollocks. Theragra chalcogramma and T. finnmarchica represent one single species 

      Ursvik, Anita; Breines, Ragna; Christiansen, Jørgen Schou; Fevolden, Jan-Erik; Coucheron, Dag H.; Johansen, Steinar D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-06-07)
      Background: The walleye pollock (Theragra chalcogramma) and Norwegian pollock (T. finnmarchica) are confined to the North Pacific and North Atlantic Oceans, respectively, and considered as distinct species within the family Gadidae. We have determined the complete mtDNA nucleotide sequence of two specimens of Norwegian pollock and compared the sequences to that of 10 specimens of walleye pollock ...
