The murine albino-deletion complex developed as part of the Oak Ridge specific-locus test covers 6–11 cM of chromosome 7. This complex has proven to be a valuable resource for localizing traits to a small target region suitable for positional cloning. In this study, we mapped the endpoints of deletions in this complex using all of the available Mit simple-sequence length polymorphism (SSLP) markers. Concurrently, this mapping has determined the map order of nearly all of the SSLP markers, most of which were previously unresolved. The SSLP-based deletion map was confirmed and genetic distances were determined using the European Collaborative Interspecific Backcross panel of nearly a thousand mice. The average SSLP marker resolution is 0.3–0.4 cM, comparable to the cloning capacity of yeast artificial chromosomes (YACs). The SSLP markers were then used to construct a genetically anchored YAC framework map that further confirms the deletion map. We find that the largest deleted region distal to Tyr is about two to three times larger than the largest proximal deleted region, and the original C3H/101 regions flanking the deletions (moved to an St2A cch/cch background) are smaller than anticipated, which we suggest may result from increased recombination rates immediately flanking the deleted regions.

Abstract We have developed a powerful new tool for the physical analysis of genomes called Ty1-mediated chromosomal fragmentation and have used the method to map 24 retrotransposon insertions into two different mousederived yeast artificial chromosomes (YACs). Expression of a plasmid-encoded GAL1:Ty1 fusion element marked with the retrotransposition indicator gene, ade2AI, resulted in a high fraction of cells that sustained a single Ty1 insertion marked with ADE2. Strains in which Ty1ADE2 inserted into aYAC were identified by cosegregation of the ADE2 gene with the URA3-marked YAC. Ty1ADE2 elements also carried a site for the endonuclease I-DmoI, which we demonstrate is not present anywhere in the yeast genome. Consequently, I-DmoI cleaved a single chromosome or YAC at the unique site of Ty1ADE2 insertion, allowing rapid mapping of integration events. Our analyses showed that the frequency of Ty1ADE2 integration into YACs is equivalent to or higher than that expected based on random insertion. Remarkably, the 50-kb transcription unit of the mouse Steel locus was shown to be a highly significant hotspot for Ty1 integration. The accessibility of mammalian transcription units to Ty1 insertion stands in contrast to that of yeast transcription units.

We have determined the structural organization and functional roles of centromere-specific DNA sequence repeats in cen1, the centromere region from chromosome I of the fission yeast Schizosaccharomyces pombe. cen1 is composed of various classes of repeated sequences designated K', K"(dgl), L, and B', arranged in a 34-kb inverted repeat surrounding a 4- to 5-kb nonhomologous central core. Artificial chromosomes containing various portions of the cen1 region were constructed and assayed for mitotic and meiotic centromere function in S. pombe. Deleting K' and L from the distal portion of one arm of the inverted repeat had no effect on mitotic centromere function but resulted in greatly increased precocious sister chromatid separation in the first meiotic division. A centromere completely lacking K' and L, but containing the central core, one copy of B' and K" in one arm, and approximately 2.5 kb of the core-proximal portion of B' in the other arm, was also fully functional mitotically but again did not maintain sister chromatid attachment in meiosis I. However, deletion of K" from this minichromosome resulted in complete loss of centromere function. Thus, one copy of at least a portion of the K" (dgl) repeat is absolutely required but is not sufficient for S. pombe centromere function. The long centromeric inverted-repeat region must be relatively intact to maintain sister chromatid attachment in meiosis I.
