Project description:Two groups of serologically confirmed ADV infected mink were used to analyze the association of Single Nucleotide Polymorphisms with Aleutian disease (AD) resistance. Group I (n=97) was comprised of disease susceptible (ADS) animals, with disease related hyper-gammaglobulinemia confirmed by the lowered albumin: IgG ratio (A: IgG); and Group II (n=97) contained disease resistant (ADR) animals with normal A: IgG ratio. The phenotypic assignment into the groups was done according to previously validated MALDI-TOF A: IgG ratio of high reproducibility in ADV infected animals. Illumina Hiseq 2500 sequencing was used to produce sequence libraries which were biocomputationally analyzed the genome wide spread SNPs where then associated with the disease susceptible and resistant groups of animals. There was a clear over-dominance for the GATOR complex protein NPRL3 isoform X6, with a very strong effect on the differences between the animals of ADS and the ADR groups. A minor effect was observed around the HLA complex, however scattered over more genes in this area. The Protocadherin Fat 3 (FAT3) or it neighborhood could also be regarded as a candidate aerea influencing the outcome of the infection. In the absence of vaccination, and in the light of eradication failures, the results provide the foundation for the development of genomic tests, as the basis for assisted breeding for disease resistance. Additionally, the results could be useful in investigations of genetic basis of the resistance of animal infections of major economic importance, e.g. African swine fever (ASF).

Project description:The American mink (Neovison vison) is a semiaquatic species of mustelid native to North America. It's an important animal for the fur industry. Many efforts have been made to locate genes influencing fur quality and color, but this search has been impeded by the lack of a reference genome. Here we present the first draft genome of mink. In our study, two mink individuals were sequenced by Illumina sequencing with 797?Gb sequence generated. Assembly yielded 7,175 scaffolds with an N50 of 6.3?Mb and length of 2.4?Gb including gaps. Repeat sequences constitute around 31% of the genome, which is lower than for dog and cat genomes. The alignments of mink, ferret and dog genomes help to illustrate the chromosomes rearrangement. Gene annotation identified 21,053 protein-coding sequences present in mink genome. The reference genome's structure is consistent with the microsatellite-based genetic map. Mapping of well-studied genes known to be involved in coat quality and coat color, and previously located fur quality QTL provide new knowledge about putative candidate genes for fur traits. The draft genome shows great potential to facilitate genomic research towards improved breeding for high fur quality animals and strengthen our understanding on evolution of Carnivora.

Project description:The release of domestic organisms to the wild threatens biodiversity because the introduction of domestic genes through interbreeding can negatively impact wild conspecifics via outbreeding depression. In North America, farmed American mink (Neovison vison) frequently escape captivity, yet the impact of these events on functional genetic diversity of wild mink populations is unclear. We characterized domestic and wild mink in Ontario at 17 trinucleotide microsatellites located in functional genes thought to be associated with traits affected by domestication. We found low functional genetic diversity in both mink types, as only four of 17 genes were variable, yet allele frequencies varied widely between captive and wild populations. To determine whether allele frequencies of wild populations were affected by geographic location, we performed redundancy analysis and spatial analysis of principal components on three polymorphic loci (AR, ATN1 and IGF-1). We found evidence to suggest domestic release events are affecting the functional genetic diversity of wild mink, as sPCA showed clear distinctions between wild individuals near mink farms and those located in areas without mink farms. This is further substantiated through RDA, where spatial location was associated with genetic variation of AR, ATN1 and IGF1.
