      Glover, Kevin; Harvey, Alison C.; Hansen, Tom Johnny; Fjelldal, Per Gunnar; Besnier, Francois; Bos, J.B.; Ayllon, Fernando; Taggart, John B.; Solberg, Monica Favnebøe (Peer reviewed; Journal article, 2020)
      Triploid organisms have three sets of chromosomes. In Atlantic salmon, hydrostatic pressure treatment of newly fertilized eggs has been extensively used to produce triploids which are functionally sterile due to their ...
    • 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 (Peer reviewed; Journal article, 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 ...
    • Development of supermale and all-male Atlantic salmon to research the vgll3 allele - puberty link 

      Fjelldal, Per Gunnar; Hansen, Tom Johnny; Wargelius, Anna; Ayllon, Fernando; Glover, Kevin Alan; Schulz, Rüdiger W.; Fraser, Thomas (Peer reviewed; Journal article, 2020)
      Farmed Atlantic salmon are one of the most economically significant global aquaculture products. Early sexual maturation of farmed males represents a significant challenge to this industry and has been linked with the vgll3 ...
    • Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface 

      Besnier, Francois; Solberg, Monica Favnebøe; Harvey, Alison C.; Carvalho, Gary R.; Bekkevold, Dorte; Taylor, Martin I.; Creer, Simon; Nielsen, Einar Eg; Skaala, Øystein; Ayllon, Fernando; Dahle, Geir; Glover, Kevin (Peer reviewed; Journal article, 2020)
      Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental demonstration ...
    • Evolutionary drivers of kype size in atlantic salmon (salmo salar): domestication, age and genetics 

      Perry, William; Solberg, Monica Favnebøe; Besnier, Francois; Dyrhovden, Lise; Matre, Ivar Helge; Fjelldal, Per Gunnar; Ayllon, Fernando; Creer, Simon; Llewellyn, Martin; Taylor, Martin I.; Carvalho, Gary; Glover, Kevin (Journal article; Peer reviewed, 2019)
      The diversity of reproduction and associated mating patterns in Atlantic salmon (Salmo salar) has long captivated evolutionary biologists. Salmo salar exhibit strategies involving migration, bold mating behaviours and ...
    • Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations 

      Jørgensen, Katarina Mariann; Wennevik, Vidar; Sørvik, Anne Grete Eide; Unneland, Laila; Prusov, Sergey; Ayllon, Fernando; Glover, Kevin (Journal article; Peer reviewed, 2018)
      Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic salmon ...
    • 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 (Journal article; Peer reviewed, 2019)
      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 ...
    • 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 (Journal article; Peer reviewed, 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 ...
    • 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 (Journal article; Peer reviewed, 2018)
      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 ...
