B chromosomes of the Chinese raccoon dog (Nyctereutes procyonoides procyonoides Gray) contain inactive NOR-like sequences
ثبت نشده
چکیده
Application of the FISH technique with the human 28S rDNA probe on metaphase spreads of the Chinese raccoon dog confirmed the presence of the NOR sequences on three A autosome pairs and the Y chromosome. Moreover, NOR-like sequences were found on the B chromosomes in the telomeric region of the long arm and in the proximal half of these chromosomes.

Identification of polymorphisms and transcriptional activity of the proto-oncogene KIT located on both autosomal and B chromosomes of the Chinese raccoon dog.
B chromosomes are dispensable and co-exist with autosomal and sex chromosomes. The karyotype of the Chinese raccoon dog (Nyctereutes procyonoides procyonoides) comprises 0-4 B chromosomes. The proto-oncogene KIT is found on all B chromosomes of the Chinese raccoon dog. In the present study, partial DNA and mRNA sequences of KIT were amplified and sequenced from four individuals containing B chr...

The quantity, quality, and distribution of eumelanin and pheomelanin determine a wide variety of coat colors in animals. Three coat color variants exist in farmed wild-type Chinese raccoon dog (Nyctereutes procyonoides procyonoides), which is an important fur-bearing animal species. The ASIP gene is an important candidate gene for coat color variation in some species. In this study, the complet...

The Chinese raccoon dog (Nyctereutes procyonoides procyonoides) is one of the most important fur-bearing animal species. The dominant white individual, a coat color variant in farmed Chinese raccoon dog, shows a completely white phenotype over the entire body. The KIT and EDNRB genes have been reported to be associated with the dominant white coat color in some mammalian species. In the present...

Chinese raccoon dog (Nyctereutes procyonoides procyonoides) is one of the most important fur-bearing animal species. Information about the genetic background of farmed Chinese raccoon dogs is limited. In this study, 17 polymorphic microsatellite markers were isolated and identified from an (AC)n-microsatellite-enriched library of Chinese raccoon dogs. The number of alleles per locus ranged from...
