We revised the bush dog karyotype and performed a comparative sequence analysis of satellite and satellite-like DNAs in 6 canids: the bush dog, domestic dog (<i>Canis familiaris</i>, 2n = 78), grey wolf (<i>C. lupus</i>, 2n = 78), Chinese raccoon dog (<i>Nyctereutes procyonoides procyonoides</i>, 2n = 54+B), red fox (<i>Vulpes vulpes</i>, 2n = 34+B), and arctic fox (<i>V. lagopus</i>, 2n = 48-50) to specify the species position among Canidae. Using FISH with painting and BAC probes, we found that the distribution of canid evolutionarily conserved chromosome segments in the bush dog karyotype is similar to that of the domestic dog and grey wolf. The bush dog karyotype differs by 2 acrocentric chromosome pairs formed by tandem fusions of the canine (29;34) and (26;35) orthologues. An interstitial signal of the telomeric probe was observed in the (26;35) fusion site in the bush dog indicating a recent evolutionary origin of this rearrangement. Sequences and hybridisation patterns of satellite DNAs were compared, and a phylogenetic tree of the 6 canid species was constructed which confirmed the bush dog position close to the wolf-like canids, and apart from the raccoon dog and foxes.</p><p><b></b><i></i><u></u><sub></sub><sup></sup><br></p> 2019-10-09 08:01:32 Arctic fox BAC probes Chinese raccoon dog Domestic dog FISH Grey wolf Red fox Telomeric repeats
