    Genetic studies on cycloheximide-resistant strains of Schizosaccharomyces pombe

    Cycloheximide-resistant mutants of Schizosaccharomyces pombe were isolated either as spontaneous mutants or after mutagenic treatment with nitrous acid, UV and N-methyl-N´-nitro-N-nitrosoguanidine (MNNG). Twenty-...

    Characterisation of the ribosomal proteins from Schizosaccharomyces pombe by two-dimensional polyacrylamide gel electrophoresis

    The 80S ribosome of Schizosaccharomyces pombe contains 93 proteins as determined by twodimensional electrophoresis on polyacrylamide gels. Of these, 76 are basic and 17 are acidic at pH 8.7. 38 proteins could be ...

    Genetical studies on revertants to sensitivity from a cycloheximide resistant strain of Schizosaccharomyces pombe

    Six UV induced cycloheximide-sensitive revertants were isolated from the cyh1-C7 strain of Schizosaccharomyces pombe which is resistant to cycloheximide. In all cases reversion to sensitivity was due to a forward...

    Characterisation of ribosomes from drug resistant strains of Schizosaccharomyces pombe in a poly U directed cell free protein synthesising system

    Mutants of Schizosaccharomyces pombe were isolated as resistant either to trichodermin or to anisomycin. Growth tests showed that the majority of mutants isolated were cross resistant to both drugs and also to cy...

    Multiple drug resistance in the fission yeast Schizosaccharomyces pombe: Evidence for the existence of pleiotropic mutations affecting energy dependent transport systems

    The uptake of L-tyrosine into wild type and antibiotic resistant strains of Schizosaccharomyces pombe requires an energy source, is initially linear with respect to time, is inhibited by 2,4-dinitrophenol and sod...

    A new mutation for multiple drug resistance and modified plasma membrane ATPase activity in Schizosaccharomyces pombe

    The mutant JV66 was selected from the wild type strain of S. pombe 972h− ade7-413 by its ability to grow on solid rich medium containing 200 μg Dio-9/ml. The single nuclear mutation, designated pma1 gives resista...
