The alignment of genome linkage maps, defined primarily by segregation of sequence-tagged site (STS) markers, with BAC contig physical maps and full genome sequences requires high throughput mechanisms to identify BAC clones that contain specific STS. A powerful technique for this purpose is multi-dimensional hybridization of "overgo" probes. The probes are chosen from available STS sequence data by selecting unique probe sequences that have a common melting temperature. We have hybridized sets of 216 overgo probes in subset pools of 36 overgos at a time to filter-spotted chicken BAC clone arrays. A four-dimensional pooling strategy, including one degree of redundancy, has been employed. This requires 24 hybridizations to completely assign BACs for all 216 probes. Results to date are consistent with about a 10% failure rate in overgo probe design and a 15-20% false negative detection rate within a group of 216 markers. Three complete rounds of overgo hybridization, each to sets of about 39,000 BACs (either BamHI or EcoRI partial digest inserts) generated a total of 1853 BAC alignments for 517 mapped chicken genome STS markers. These data are publicly available, and they have been used in the assembly of a first generation BAC contig map of the chicken genome.
