We have constructed a yeast artificial chromosome (YAC) and P1 contig in the 8p12-p21 region. The contig comprises 16 overlapping YAC clones and 44 overlapping P1 clones. Twelve dinucleotide-repeat polymorphic sequence- tagged site (STS) markers that were previously isolated mainly from these YAC and P1 clones were genetically mapped. A total of 46 nonpolymorphic STS markers were newly established mainly from the YAC and P1 clone end fragments, and 28 of the 46 nonpolymorphic STSs, as well as the 12 polymorphic STSs, were also mapped physically onto the contig based on STS content analysis of YAC pools and of the P1 and YAC clones. As a result, the YAC and P1 clones were assembled into a single contig covering a minimum of 1.5 Mb physically and 2.8 cM genetically with 12 polymorphic and 28 nonpolymorphic STSs within the 8p12-p21 region. Average STS spacing in the contig was estimated to be 40 kb/STS. In addition, further characterization of the contig suggested that this contig includes a region where genetic recombination occurs frequently. Thus, the resulting cloned region, together with densely mapped STS markers on the contig, should help to promote our understanding of this region.
