title: Genetic mapping of arg, cpa, car and tsm genes in Saccharomyces cerevisiae by trisomic analysis.
abstract: By use of a set of 8 aneuploid strains of the yeast Saccharomyces cerevisiae, carrying from 1 to 5 identified disomic chromosomes, in crosses to a set of haploid strains collectively bearing 11 unmapped genes, the following chromosome assignments were obtained for these unmapped genes: arg80 on XIII;arg3 on X;car2 on XII; cpa1 and tsm8740 on XV; tsm7269 (=rna6) on II; cpa2 on X or XV; arg82 and tsm4572 on III, IV or XVI; car1 and arg81 on II, IV, VI, VII or XVI. Linkage tests between the unmapped genes and markers located on the chromosomes that had been designated as possible carriers by the previous analysis allowed 8 genes to be localized. The remaining three genes, cpa2, car1 and arg81 (located on fragment F8), could not be positioned on any of the chromosomes indicated by the trisomic analysis, in spite of testing for linkage to markers covering most of the known regions of these chromosomes.
