Summary
In Saccharomyces cerevisiae, mutants were isolated which show high resistance to the aminoglycoside paromomycin. Amino acid incorporation of mitochondria isolated from such mutant strains proved also to be paromomycin resistant. All of them are cross-resistant to the structurally related antibiotic neomycin. Three independent methods revealed the resistance to be extrachromosomally, presumably mitochondrially inherited.
