Abstract: | Dictyostelium discoideum DNA fragments have been inserted into the chimeric bacterium-yeast plasmid YEp13. Recombinant plasmids were used to transform yeast using a strain of Saccharomyces cerevisiae deficient in OMP decarboxylase activity. Several clones were selected for growth in uracil-free medium. One clone was further analysed and contains a plasmid with a segment of D. discoideum DNA which complements a yeast ura3 mutation. |
