| 英文摘要 | Genome-wide homologymaps among dog (Canis familiaris,CFA, 2n¼78),African lion (Panthera leo, PLE, 2n¼38), clouded leopard (Neofelis nebulosa, NNE, 2n¼38) and Malayan sun bear (Helartos malayanus, HMA, 2n¼74) have been established by chromosome painting using a complete set of dog probes. In total, chromosome-speci¢c painting probes from the 38 dog autosomes reveal 69, 69 and 73 conserved segments in African lion, clouded leopard andMalayan sun bear, respectively. The chromosomal painting results show that the African lion and clouded leopard have an identical karyotype which, in turn, is similar to that previously published for the cat (Felis catus, FCA 2n¼38). The ¢ndings con¢rm and extend other studies that show felids to be karyotypically conserved. In contrast, ursids, including the Malayan sun bear, have a relatively highly rearranged karyotype in comparison with other carnivores. The 2n¼74 karyotype of the Malayan sun bear, which is believed to closely resemble the ancestral karyotype of the Ursidae, could have evolved from the 2n¼42 putative ancestral carnivore karyotype by an inversion and 16 centric ¢ssions. Independent fusions of the acrocentric ancestral chromosomes have generated the unique karyotypes of the giant panda and the spectacled bear. |
