TL;DR: It is shown that after 100 million years of evolution the two ancestral subgenomes have remained extremely collinear, despite the loss of half of the duplicated protein-coding genes, mostly through pseudogenization.
Journal ArticleDOI
A Microsatellite Linkage Map of Rainbow Trout (Oncorhynchus mykiss) Characterized by Large Sex-Specific Differences in Recombination Rates
Takashi Sakamoto,Roy G. Danzmann,Karim Gharbi,Pamela Howard,Akiyuki Ozaki,Sok Kean Khoo,Rachael A. Woram,Nobuaki Okamoto,Moira M. Ferguson,Lars-Erik Holm,René Guyomard,Bjørn Høyheim +11 more
TL;DR: A genetic linkage map for a tetraploid derivative species, the rainbow trout (Oncorhynchus mykiss), using 191 microsatellite, 3 RAPD, 7 ESMP, and 7 allozyme markers in three backcross families is constructed.
Journal ArticleDOI
An immune-related gene evolved into the master sex-determining gene in rainbow trout, Oncorhynchus mykiss.
Ayaka Yano,René Guyomard,Barbara Nicol,Elodie Jouanno,Edwige Quillet,Christophe Klopp,Cédric Cabau,Olivier Bouchez,Alexis Fostier,Yann Guiguen +9 more
TL;DR: It is demonstrated that master sex determinants can arise from the de novo evolution of genes that have not been previously implicated in sex differentiation through the demonstration that sdY is a novel vertebrate master sex-determining gene not related to any known sex-differentiating gene.
Journal ArticleDOI
DNA sequence variation of the mitochondrial control region among geographically and morphologically remote European brown trout Saltno trutta populations
TL;DR: This study exemplified the usefulness of mitochondrial DNA sequence analysis for estimating phylogenetic relationships within S. trutta populations by determining DNA sequence variation in segments of the mitochondrial control region for 151 individuals representing 24 populations.
Journal ArticleDOI
Comparative analysis of microsatellite and allozyme markers: a case study investigating microgeographic differentiation in brown trout (Salmo trutta)
TL;DR: A comparative study between microsatellite and allozyme markers was conducted on natural populations of resident brown trout sampled over a reduced geographical scale and on hatchery strains, indicating that isolation-by-distance acted significantly on brown trout populations.
