Chromosomal localization of the BLV receptor candidate gene in cattle, sheep, and goat

摘要

The BLV receptor candidate gene has been localized precisely on cattle, goat, and sheep chromosomes using nonradioactive in situ hybridization and simultaneous fluorescent R-banding. The probe, a whole plasmid containing a 2.3-kb bovine cDNA fragment encoding part of this gene, was nick-translated in the presence of biotin-11-dUTP. It hybridized on band q15 of cattle chromosome 7, goat chromosome 7, and sheep chromosome 5, thus confirming the homoeology based on banding patterns among the chromosomes of these three species.
