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 ... -
Autosomal sdY pseudogenes explain discordances between phenotypic sex and DNA marker for sex identification in Atlantic salmon
Ayllon, Fernando; Solberg, Monica Favnebøe; Besnier, Francois; Fjelldal, Per Gunnar; Hansen, Tom Johnny; Wargelius, Anna; Edvardsen, Rolf Brudvik; Glover, Kevin (Journal article; Peer reviewed, 2020)Despite the key role that sex-determination plays in evolutionary processes, it is still poorly understood in many species. In salmonids, which are among the best studied fishes, the master sex-determining gene sexually ... -
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. ... -
Transcriptome sequencing of Atlantic salmon ( Salmo salar L.) notochord prior to development of the vertebrae provides clues to regulation of positional fate, chordoblast lineage and mineralisation
Wang, Shou; Furmanek, Tomasz; Kryvi, Harald; Krossøy, Christel; Totland, Geir K.; Grotmol, Sindre; Wargelius, Anna (Peer reviewed; Journal article, 2014-02-19)Background In teleosts such as Atlantic salmon (Salmo salar L.), segmentation and subsequent mineralisation of the notochord during embryonic stages are essential for normal vertebrae formation. However, the molecular ... -
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 ...
