Bovine synteny group U7, previously assigned to G-banded chromosome 25 in the ISCNDA nomenclature, assigns to R-banded chromosome 29.
Four microsatellite-containing bovine cosmids have been regionally localized by fluorescence in situ hybridization to bovine R-banded chromosome 29 (BTA29) and to the 1;29 translocated chromosomes. PCR-analyses of a somatic hybrid cell panel assigned the four microsatellites to synteny group U7. One of the cosmids (IDVGA7) has been previously mapped to G-banded BTA25 allowing to assign U7 to this chromosome. Hence, it is concluded that G-banded BTA25 corresponds to R-banded BTA29. The occurrence of other misleading nomenclatures for small bovine chromosomes is discussed.
