Linking transcriptomic and genomic variation to growth in brook charr hybrids (Salvelinus fontinalis, Mitchill)

Usefulness of heterologous microsatellites obtained from brook charr, Salvelinus fontinalis Mitchill, in other Salvelinus species.

The transcriptional landscape of cross-specific hybrids and its possible link with growth in brook charr (Salvelinus fontinalis Mitchill).

The genetic mechanisms underlying hybridization are poorly understood despite their potentially important roles in speciation processes, adaptative evolution, and agronomical innovation. In this study, transcription profiles were compared among three populations of brook charr and their hybrids using microarrays to assess the influence of hybrid origin on modes of transcription regulation inher...

Major disruption of gene expression in hybrids between young sympatric anadromous and resident populations of brook charr (Salvelinus fontinalis Mitchill).

Genome-wide analyses of the transcriptome have suggested that male-biased genes are the first targets of genomic incompatibilities (g.i.) in inter-specific hybrids. However, those studies have almost invariably focused on Drosophila species that diverged at least 0.9 Ma, and with sterile male hybrids. Here, we use microarrays to analyse patterns of gene expression in very closely related (diver...

The rise and fall of isolation by distance in the anadromous brook charr (Salvelinus fontinalis Mitchill).

Geographic patterns of genetic diversity depend on a species' demographic properties in a given habitat, which may change over time. The rates at which patterns of diversity respond to changes in demographic properties and approach equilibrium are therefore pivotal in our understanding of spatial patterns of diversity. The brook charr Salvelinus fontinalis is a coastal fish exhibiting limited m...

Congruence in Control-Region Sequence and Restriction- Site Variation in Mitochondrial DNA of Brook Charr (Salvelinus fontinalis Mitchill)’

We compared the congruence in genetic variation and phylogenetic relationships among mitochondrial DNA (mtDNA) haplotypes detected with restriction-fragment-length polymorphisms (RFLPs) and sequence analysis in the brook charr, Sulvelinus fontinalis Mitchill. This was accomplished by analyzing variation both at 172 restriction sites subsampling 903 bp over the entire mitochondrial genome and in...
