Detection of QTL with effects on osmoregulation capacities in the rainbow trout (Oncorhynchus mykiss).

En utilisant les Technologies de l’Information et de la Communication (TIC) ainsi que des logiciels et standards internationaux pour la gestion des métadonnées, l’analyse et le partage de données ainsi que la collaboration scientifique, CeSGO propose la mise en place d’une plate-forme e-Science couplée à un environnement virtuel de recherche centré sur les besoins des communautés des sciences de la vie.

There is increasing evidence that the ability to adapt to seawater in teleost fish is modulated by genetic factors. Most studies have involved the comparison of species or strains and little is known about the genetic architecture of the trait. To address this question, we searched for QTL affecting osmoregulation capacities after transfer to saline water in a nonmigratory captive-bred population of rainbow trout. A QTL design (5 full-sib families, about 200 F2 progeny each) was produced from a ...

90 trouts are transferred from freshwater to seawater during 21 days. Plamsatic ion concentrations and gill transcriptome expression are studied and related to better understand seawater acclimation functional processes on Rainbow trout.
