title: Further characterization of a somatic cell hybrid panel: ten new assignments to the bovine genome.
abstract: Thirty-six partially characterized hamster-bovine hybrid cell lines were used for the determination of synteny groups. Sixteen additional reference loci, selected for their coverage of the bovine genome, were analysed on these hybrid cells. This increases to 25 the number of synteny groups detected. This panel was then used to make synteny assignments for 10 additional loci, eight by Southern blotting (COL1A1, COL1A2, FAS, CTSB, CTSL, CHRNG, HEXB and HTR1A) and two by polymerase chain reaction (PCR) amplification (HRH1 and ETH1112). These loci were assigned to international synteny groups U12 (HRH1), U13 (COL1A2), U17 (CHRNG), U21 (COL1A1, FAS), U29 (ETH1112), to chromosome 20 (U14 or U25) for HEXB and HTR1A, and to the same local synteny group (A), which is probably U18, for CTSB and CTSL. For three loci already mapped in humans (COL1A1, COL1A2 and CHRNG), the present results are in accordance with the predictions based on comparative mapping between the human and bovine species.
