Abstract
Hybrid yeast strains were constructed using haploid Saccharomyces cere visiae and Saccharomyces cerevisiae var. diastaticus strains to get ha ploid meiotic recombinants having more than one copy of STA1, STA2, an d STA3 genes. STA genes were localized on the chromosomes by pulsed fi eld gel electrophoresis. Working gene dosage effects were found among STA genes in liquid starch medium, indicating low levels of glucose re pression. Growth of strains, however, was not influenced by their STA copy number.
