Multidirectional chromosome painting between the Hirola antelope (Damaliscus hunteri, Alcelaphini, Bovidae), sheep and human

Chromosome specific painting probes of human, sheep and the Hirola antelope (Damaliscus hunteri) derived by flow sorting of chromosomes were used in multi directional chromosome painting experiments to better define the karyological relationship within Bovidae species (specifically, Caprini and Alcelaphini tribes) and humans. Although not all chromosomes of Damaliscus hunteri could be resolved into single peaks by flow-sorting we managed to present a complete homology map for chromosomes between the three species. When comparing the karyotype of Damaliscus hunteri with human all of the main known motives in mammalian chromosome evolution are present (i.e. associations of human homologous chromosomes 3-21, 4-8, 7-16, 14-15, 16-19 and two forms of 12-22) which were also confirmed with the sheep paint probes. Further, we observed those patterns that have been described as common derived traits for artiodactyls (i.e. associations of human homologous chromosomes 5/19 and a complex alternating pattern of hybridizations with human chromosome 14 and 15 probes). As known from classical karyotyping some of the 2 Damaliscus chromosomes are biarmed and were supposedly involved in Robertsonian translocations frequently found in karyotype evolution of bovids. We refined these rearrangements with the molecular probes and also delineated a chromosome painting pattern that should be the result of a paracentric inversion in the Damaliscus hunteri karyotype. This study demonstrates that multidirectional chromosome painting will be a valuable tool for the investigation of the dynamics of chromosome evolut ion in exotic bovid species.

G- and C-banded karyotypes of the genus Oryx were compared using the standard karyotype of Bos taurus. Chromosomal complements were 2n = 56 in O. gazella gazella, 2n = 58 in O. g. beisa and O. g. callotis, 2n = 56–58 in O. dammah, and 2n = 57–58 in O. leucoryx. The number of autosomal arms in all karyotypes was 58. Nearly all variation in diploid number was the result of three independent centric fusions, but one 2n = 57 specimen of O. g. gazella deviated from the normal complement of 2n = 56 due to XXY aneuploidy. A 2;17 centric fusion was fixed in O. g. gazella, whereas O. g. beisa and O. g. callotis lacked this fusion and had indistinguishable karyotypes. Oryx dammah was polymorphic for a 2;15 centric fusion, and O. leucoryx was polymorphic for an 18;19 centric fusion. The five Oryx taxa shared a fixed 1;25 centric fusion; the small acrocentric element involved in the 1;25 fusion was identified by fluorescence in situ hybridization using a cosmid specific to Bos chromosome 25. The X and Y chromosomes were also conserved among the five taxa. Oryx g. gazella differed from the other Oryx species because of the fixed 2;17 centric fusion. This difference reflects an apparently longer period of geographic isolation between O. g. gazella and other populations of Oryx, and it is consistent with the classification of O. gazella and O. beisa as distinct species (see Kingdon, 1997). The lack of monobrachial relationships among the Oryx taxa indicates that sterility barriers between species have not developed. Viability of hybrid offspring constitutes a threat to captive breeding programs designed for endangered species conservation; in the case of Oryx, the 2;15, 2;17, and 18;19 metacentrics could serve as marker chromosomes for assessing hybridization between certain Oryx taxa.
