Through a combination of radiation hybrid mapping and studies by FISH and zoo-FISH we have made a comparative investigation of the distal portion of rat chromosome 1 (RNO1) and the entire mouse chromosome 19 (MMU19). It was found that homologous segments of RNO1 and MMU19 are similar in banding morphology and in length as determined by several different methods, and that the gene order of the 46 genes studied appears to be conserved across the homologous segments in the two species. High-resolution zoo-FISH techniques showed that MMU19 probes highlight only a continuous segment on RNO1 (1q43-qter), with no detectable signals on other rat chromosomes. We conclude that these data suggest the evolutionary conservation of a chromosomal segment from a common rodent ancestor. This segment now constitutes the entire MMU19 and a large segment distally on RNO1q in the mouse and rat, respectively.  相似文献

Overall, the probe map fromDXWas70 toAmg encompasses 72 cM and includes 103 loci. Eight of these have been designated reference loci (see Table 2 and previous section) on account of their wide usage that would enable the cross reference of independent maps created in different laboratories. Reference loci are to be readily available and easily used probes for Southern hybridization. By and large, they will be STSs, regeneratable by PCR, and correspond to a known gene. In addition, on the mouse X Chr, there is a reference locus from each of the known conserved linkage groups found between the mouse and human X Chrs. All the loci, barDXWas31, represent conserved sequences. Committee Members: D. Adler, P.J. Barnard, Y. Boyd, N. Brockdorff, J. Derry, C. Disteche, C. Faust, M.F. Lyon, S. Rastan, M. Seldin and L.
