CIGENE researchers have contributed to two new papers on genome evolution after whole genome duplication, one published in Genome biology and one accepted for publication in Nature Genetics!
Congrats Fabian, Sigbjørn, Torgeir, and Simen!
A pre-print of our new paper “Diet And Life Stage Associated Remodeling Of Lipid Metabolism Regulation In The Duplicated Atlantic Salmon Genome” is out on bioRxiv.
Congrats to Gareth and Tom for a fantastic job on this!
Nicola Barson, Simen Sandve and Torgeir Hvidsten publishes a popular science piece on sex and gender evolution in Aftenposten (http://www.aftenposten.no/viten/-Hvorfor-har-vi-sex-619458b.html)
Caught some attention on the national radio too: https://radio.nrk.no/serie/p3morgen#t=46m59s

Tina Graceline Kirubakaran at CIGENE made the front page of Molecular Ecology with her first paper as main author. She and her coauthors showed that Arctic and coastal cod are kept genomically different by two adjacent chromosomal inversions.

Eighty million years ago, a mutant fish was born that turned out to be very successful. This mutant had a double set of hereditary material – 50 chromosomes instead of the usual 25 – and it became the ancestor of all the salmonid fishes. A lot has happened during the course of this speciation and diversification: chromosomes have split up and been jumbled around, and many gene duplicates have been lost. But even today, about half of salmon genes exist in two copies, possibly linked to the ecological flexibility of salmonids. The CIGENE team have driven the sequencing of the salmon genome from its inception to its recent publication in Nature. Continue reading “Salmon genome sequence published in Nature”
