“…These markers were added to AFLP markers on the basis of inferred synteny from other rainbow trout maps in the region of the major development rate QTL. In addition, one known gene, growth hormone 1 (GH1; (Oakley and Phillips 1999), identified as a potential candidate gene for development rate, was genotyped by the identity of a single nucleotide polymorphism (SNP) in intron C. GH1 SNP genotypes were detected by the ABI SNaPshot technique (Applied Biosystems, Foster City, CA).…”

Quantitative Trait Loci × Maternal Cytoplasmic Environment Interaction for Development Rate in Oncorhynchus mykiss

et al. 2007

Effects of maternal cytoplasmic environment (MCE) on development rate in rainbow trout were evaluated within a quantitative trait loci (QTL) analysis framework. Previous research had identified QTL for development rate in doubled haploid (DH) progeny produced from a cross between the Oregon State University (OSU) and the Swanson (SW) River rainbow trout clonal lines. In this study, progeny for QTL mapping were produced from a cross between the OSU and Clearwater (CW) River clonal lines. Doubled haploids were produced from the OSU 3 CW F 1 by androgenesis using eggs from different females (or MCEs); with androgenesis, the maternal nuclear genome was destroyed by irradiation and diploidy was restored by blocking the first embryonic cleavage by heat shock. All embryos were incubated at the same temperature and development rate quantified as time to hatch. Using a linkage map constructed primarily with AFLP markers, QTL mapping was performed, including MCE covariates and QTL 3 MCE effects in models for testing. The major QTL for development rate in the OSU3SW cross overlaps with the major QTL found in this OSU 3 CW cross; effects at this locus were the same across MCEs. Both MCE and QTL 3 MCE effects contribute to variability in development rate, but QTL 3 MCE were minor and detected only at smalleffect QTL.

“…Phylogenetic relationships among salmonid species constructed from morphological data are in agreement with the ''degree'' of anadromy. Historically, the mapping of migratory life-history type upon a coarse, morphologyderived phylogenetic tree of salmonids showed a gradation in anadromy-from optionally anadromous (species consisting of either freshwater or anadromous forms) to the most derived obligately anadromous (species consisting exclusively of anadromous forms) (Hoar 1976;Oakley and Phillips 1999). However, more recent molecular Salmonidae and Salmonine phylogenies suggest multiple origins of anadromy when mapped to these trees (Stearley 1992;Stearley and Smith 1993;Oakley and Phillips 1999).…”

On a finer level, observations within species suggest plasticity in the trait and multiple parallel accounts of both the gain and the loss of anadromy in both natural and introduced populations (Quinn et al , 2001Unwin et al 2000;Pascual et al 2001;Stockwell et al 2003;Riva-Rossi et al 2007).…”

The Genetic Basis of Smoltification-Related Traits in Oncorhynchus mykiss

et al. 2008

The timing and propensity for migration between fresh-and seawater is a key theme in the diversity of life histories within the salmonid fishes. Across salmonid species, life-history strategies range from wholly freshwater-resident populations, to migratory and nonmigratory variation within populations, to populations and species that are primarily migratory. Despite the central theme of migration to the evolution of these fishes, the genetic architecture of migration-related processes is poorly understood. Using a genetic cross of clonal lines derived from migratory and nonmigratory life-history types of Onchorhynchus mykiss (steelhead and rainbow trout, respectively), we have dissected the genetic architecture of the complex physiological and morphological transformation that occurs immediately prior to seaward migration (termed smoltification). Quantitative trait loci (QTL) analyses were used to identify the number, effects, and genomic location of loci associated with smoltification-related traits, including growth and condition factor, body coloration, morphology, and osmoregulatory enzymes during the smoltification period. Genetic analyses revealed numerous QTL, but one locus in particular is associated with multiple traits in single and joint analyses. Dissecting the genetic architecture of this highly complex trait has profound implications for understanding the genetic and evolutionary basis of life-history diversity within and among migratory fishes.

“…Based on the morphological data, these two genera are thought to be sister taxa (Stearley and Smith, 1993), which also is supported by a molecular phylogenetic data of interspersed nucleotide elements (SINEs) (Murata et al, 1996). However, recent molecular phylogenetic analyses using growth hormone gene (GH) intron (Oakley and Phillips, 1999), microsatellite DNA (Angers and Bernatchez, 1997), and vitellogenin gene (Buisine, Trichet & Wolff, 2002) suggest that the genus Oncorhynchus is close to the genus Salvelinus, but not to the genus Salmo.…”

“…The subfamily Salmoninae contains five genera Brachymystax, Hucho, Salvelinus, Salmo and Oncorhynchus. Phylogenetic relationship of Salmoninae has been studied by using morphological data (Stearly and Smith, 1993) and several nuclear and mitochondrial DNA markers (Shedlock et al, 1992;Murata et al, 1993;Oohara, Sawano & Okazaki, 1997;Oakley and Phillips, 1999).…”
