    • 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)
      Background: Populations of Atlantic salmon display highly significant genetic differences with unresolved molecular basis. These differences may result from separate postglacial colonization patterns, diversifying natural ...

    • Comparison of anadromous and landlocked Atlantic salmon genomes reveals signatures of parallel and relaxed selection across the Northern Hemisphere 

      Kjærner-Semb, Erik Nordtorp; Edvardsen, Rolf Brudvik; Ayllon, Fernando; Vogelsang, Petra; Furmanek, Tomasz; Rubin, Carl-Johan; Veselov, Alexey E.; Nilsen, Tom Ole; McCormick, Stephen D.; Primmer, Craig R.; Wargelius, Anna (Journal article; Peer reviewed, 2020)
      Most Atlantic salmon (Salmo salar L.) populations follow an anadromous life cycle, spending early life in freshwater, migrating to the sea for feeding, and returning to rivers to spawn. At the end of the last ice age ~10,000 ...

    • 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. ...

    • Vgll3 and the Hippo pathway are regulated in Sertoli cells upon entry and during puberty in Atlantic salmon testis 

      Kjærner-Semb, Erik Nordtorp; Ayllon, Fernando; Kleppe, Lene; Sørhus, Elin; Skaftnesmo, Kai Ove; Furmanek, Tomasz; Segafredo, Frida Thyri; Thorsen, Anders; Fjelldal, Per Gunnar; Hansen, Tom Johnny; Taranger, Geir Lasse; Andersson, Eva; Schulz, Rüdiger W.; Wargelius, Anna; Edvardsen, Rolf (Peer reviewed; Journal article, 2018-01-30)
      Vgll3 is linked to age at maturity in Atlantic salmon (Salmo salar). However, the molecular mechanisms involving Vgll3 in controlling timing of puberty as well as relevant tissue and cell types are currently unknown. Vgll3 ...

    • The vgll3 Locus Controls Age at Maturity in Wild and Domesticated Atlantic Salmon(Salmo salar L.) Males 

      Ayllon, Fernando; Kjærner-Semb, Erik Nordtorp; Furmanek, Tomasz; Wennevik, Vidar; Solberg, Monica Favnebøe; Dahle, Geir; Taranger, Geir Lasse; Glover, Kevin; Sällman Almèn, Markus; Rubin, Carl J.; Edvardsen, Rolf; Wargelius, Anna (Peer reviewed; Journal article, 2015-11-09)
      Wild and domesticated Atlantic salmon males display large variation for sea age at sexual maturation, which varies between 1–5 years. Previous studies have uncovered a genetic predisposition for variation of age at maturity ...
