Comparative study of the bush dog (Speothos venaticus) karyotype and analysis of satellite DNA sequences and their chromosome distribution in six species of Canidae
Original language description
The bush dog (Speothos venaticus, 2n=74) is a near threatened species taxonomically classified among South American canids. We revised the bush dog karyotype, and performed a comparative sequence analysis of satellite and satellite-like DNAs in six canids: the bush dog, domestic dog (Canis familiaris, 2n=78), grey wolf (Canis lupus, 2n=78), Chinese raccoon dog (Nyctereutes procyonoides procyonoides, 2n=54+B), red fox (Vulpes vulpes, 2n=34+B) and arctic fox (Vulpes lagopus, 2n=48-50) to specify the species position among Canidae. Using fluorescence in situ hybridisation 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 two 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 six canid species was constructed which confirmed the bush dog position close to the wolf-like canids, and apart from the raccoon dog and foxes.
