A physical map of the bovine genome. Genome Biology. 8:R165 (17 pp).

Interpretive Summary: A resource describing the cattle genome was created by integrating several sources of information. A moderate resolution composite map of DNA markers was developed by combining data from five independent maps. A high-resolution physical (bacterial artificial chromosome, or BAC) map was created using fingerprints of each BAC clone and partial sequence of clones aligned with the human genome. The maps were integrated with a draft assembly of the complete bovine sequence. The maps can assist with refining the sequence assembly, and will be useful to help identify variations in DNA that affect meat and milk production.

Technical Abstract: Background Cattle are important agriculturally and relevant as a model organism. Previously described genetic and radiation hybrid (RH) maps of the bovine genome have been used to identify genomic regions and genes affecting specific traits. Application of these maps to identify influential genetic polymorphisms will be enhanced by integration with each other and with bacterial artificial chromosome (BAC) libraries. The BAC libraries and clone maps are essential for the hybrid clone-by-clone/whole-genome shotgun sequencing approach taken by the bovine genome sequencing project. Results A bovine BAC map was constructed with HindIII restriction digest fragments of 290,797 BAC clones from animals of three different breeds. Comparative mapping of 422,522 BAC end sequences (BES) assisted with BAC map ordering and assembly. A minimally overlapping set of clones, used as sequencing templates in the bovine sequencing project, was selected from the BAC map. Genotypes and pedigree from two genetic maps and marker scores from three whole-genome RH panels were consolidated on a 17,254-marker composite map, ordered with maximum likelihood procedures and projected onto common scales. Sequence similarity allowed integrating the BAC and composite maps with the bovine draft assembly (Btau3.1), establishing a comprehensive resource describing the bovine genome. The integrated maps are accessible from Conclusions Together, the BAC and composite maps provide a guide for ordering and orienting genome sequence. In addition to contributing to a high quality genome assembly, the maps are crucial resources for understanding the biology underpinning this important ruminant species so closely associated with humans.
