TI  - X chromosome evolution in the suni and eland antelope: detection of homologous 
      regions by fluorescence in situ hybridization and G-banding.
PG  - 218-22
AB  - Comparative cytogenetics and fluorescence in situ hybridization (FISH) were used 
      to track structural rearrangements in the X chromosomes of two African antelope 
      species, the eland (Taurotragus oryx; tribe Tragelaphini) and the suni (Neotragus 
      moschatus; tribe Neotragini). Using two microdissected cattle chromosome painting 
      probes (one specific for Xp-containing sequences corresponding to Xp24-->p12 of 
      the cattle X, and one specific for Xq-containing sequences corresponding to 
      Xq12-->qter), we show that intrachromosomal rearrangements distinguish the X 
      chromosomes of these species. Furthermore, there is clear evidence that, 
      superimposed on this background of intrachromosomal evolutionary change, the 
      sequences contained in the cattle Xp painting probe appear to have moved as a 
      complete unit during the repatterning of the bovid X. Although we are unable to 
      infer the order of the rearranged chromosomal segments, given the large regions 
      of homology detected by the chromosome paints, we nonetheless believe that this 
      approach (combining conventional and molecular cytogenetic studies on the X 
      chromosome) will prove useful for inferring phylogenetic relationships in the 
      family Bovidae, particularly as more probes become available.
