| Zusammenfassung: | <jats:p>Biochemical and genetic analyses have been carried out on Saccharomyces cerevisiae strains characterized in vivo as sensitive, low-level-resistant or high-level-resistant to trichothecene antibiotics. Levels of drug resistance in vitro were determined for each strain and for suitable diploids derived from them. Ribosome biogenesis was also studied in selected haploids. It is suggested that resistance in all cases results from a mutation in the gene encoding ribosomal protein L3. If this is indeed the situation, then different mutations in this same gene not only can cause low-level or high-level resistance to trichothecene antibiotics but also can affect the maturation of either 40 S or 60 S ribosomal subunits.</jats:p> |
