    • Atlantic salmon populations reveal adaptive divergence of immune related genes - a duplicated genome under selection 

      Kjærner-Semb, Erik Nordtorp; Ayllon, Fernando; Furmanek, Tomasz; Wennevik, Vidar; Dahle, Geir; Niemelä, Eero; Ozerov, Mikhail; Vähä, Juha-Pekka; Glover, Kevin; Rubin, Carl J.; Wargelius, Anna; Edvardsen, Rolf (Peer reviewed; Journal article, 2016-08-11)

    • Crude oil exposures reveal roles for intracellular calcium cycling in haddock craniofacial and cardiac development 

      Sørhus, Elin; Incardona, John P.; Karlsen, Ørjan; Linbo, Tiffany; Sørensen, Lisbet; Nordtug, Trond; van der Meeren, Terje; Thorsen, Anders; Thorbjørnsen, Maja; Jentoft, Sissel; Edvardsen, Rolf; Meier, Sonnich (Peer reviewed; Journal article, 2016-08-10)
      Recent studies have shown that crude oil exposure affects cardiac development in fish by disrupting excitation-contraction (EC) coupling. We previously found that eggs of Atlantic haddock (Melanogrammus aeglefinus) bind ...

    • Diet affects the redox system in developing Atlantic cod(Gadus morhua) larvae

      The growth and development of marine fish larvae fed copepods is superior to those fed rotifers, but the underlying molecular reasons for this are unclear. In the following study we compared the effects of such diets on ...

    • The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus) 

      Eilertsen, Mariann; Drivenes, Øyvind; Edvardsen, Rolf; Bradley, Clarissa A.; Ebbesson, Lars O.E.; Helvik, Jon Vidar (Journal article; Peer reviewed, 2014)
      The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ...

    • The genome sequence of Atlantic cod reveals a unique immune system 

      Star, Bastiaan; Nederbragt, Alexander Johan; Jentoft, Sissel; Grimholt, Unni; Malmstrøm, Martin; Gregers, Tone Fredsvik; Rounge, Trine Ballestad; Paulsen, Jonas; Solbakken, Monica Hongrø; Sharma, Animesh; Wetten, Ola Frang; Lanzén, Anders; Winer, Roger; Knight, James; Vogel, Jan-Hinnerk; Aken, Bronwen; Andersen, Øivind; Lagesen, Karin; Tooming-Klunderud, Ave; Edvardsen, Rolf; Kirubakaran, G. Tina; Espelund, Mari; Nepal, Chirag; Previti, A. Christopher; Karlsen, Bård Ove; Moum, Truls; Skage, Morten; Berg, Paul Ragnar; Gjøen, Tor; Kuhl, Heiner; Thorsen, Jim; Malde, Ketil; Reinhardt, Richard; Du, Lei; Johansen, Steinar Daae; Searle, Steve; Lien, Sigbjørn; Nilsen, Frank; Jonassen, Inge; Omholt, Stig W; Stenseth, Nils Christian; Jakobsen, Kjetill Sigurd (Peer reviewed; Journal article, 2011-09)
      Atlantic cod (Gadus morhua) is a large, cold-adapted teleost that sustains long-standing commercial fisheries and incipient aquaculture. Here we present the genome sequence of Atlantic cod, showing evidence for complex ...

    • Human-induced evolution caught in action: SNP-array reveals rapid amphi-atlantic spread of pesticide resistance in the salmon ecotoparasite Lepeophtheirus salmonis 

      Besnier, Francois; Kent, Matthew; Skern-Mauritzen, Rasmus; Lien, Sigbjørn; Malde, Ketil; Edvardsen, Rolf; Taylor, Simon; Ljungfeldt, Lina; Nilsen, Frank; Glover, Kevin (Peer reviewed; Journal article, 2014-10-26)
      Background: The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ...

    • The influence of vgll3 genotypes on sea age at maturity is altered in farmed mowi strain Atlantic salmon 

      Ayllon, Fernando; Solberg, Monica Favnebøe; Glover, Kevin; Mohammadi, Faezeh; Kjærner-Semb, Erik Nordtorp; Fjelldal, Per Gunnar; Andersson, Eva; Hansen, Tom Johnny; Edvardsen, Rolf; Wargelius, Anna (Peer reviewed; Journal article, 2019-05-06)
      Background: In Atlantic salmon in the wild, age at maturity is strongly influenced by the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known significantly advance or delay age at maturity. ...

    • Molecular evidence that only two opsin subfamilies, the blue light- (SWS2) and green light-sensitive (RH2), drive color vision in Atlantic cod (Gadus morhua) 

      Valen, Ragnhild; Edvardsen, Rolf; Søviknes, Anne Mette; Drivenes, Øyvind; Helvik, Jon Vidar (Peer reviewed; Journal article, 2014-12-31)
      Teleosts show a great variety in visual opsin complement, due to both gene duplication and gene loss. The repertoire ranges from one subfamily of visual opsins (scotopic vision) including rod opsin only retinas seen in ...

    • The two-step development of a duplex retina involves distinct events of cone and rod neurogenesis and differentiation 

      Valen, Ragnhild; Eilertsen, Mariann; Edvardsen, Rolf; Furmanek, Tomasz; Rønnestad, Ivar; van der Meeren, Terje; Karlsen, Ørjan; Nilsen, Tom Ole; Helvik, Jon Vidar (Peer reviewed; Journal article, 2016-08)
