Abstract/OtherAbstract:
High-resolution chromosomal fluorescence in situ hybridization (FISH) and R-banding allowed the chromosomal localization of the beta-defensin gene cluster (DEFB@) to chromosome band 1p12 in the river buffalo (Bubalus bubalis, 2n = 50) and to band 24q13 in sheep (Ovis aries, 2n = 54), according to standard nomenclatures. The localizations permitted the tentative assignment of the entire bovine syntenic group U25 to these chromosomes. A FISH mapping control on cattle chromosomes confirmed the localization of DEFB@ in the homoeologous chromosome and chromosome band. Comparisons were made between river buffalo chromosome 1p and the homoeologous cattle chromosome on standard karyotypes; the results are discussed in light of gene assignments, extensive chromosome band conservation among the Bovidae, and inconsistencies in domestic cattle chromosome nomenclatures.
