[Nuclear suppression of a mitonchondrial mutation of tetracycline resistance in Saccharomyces cerevisiae].

Nuclear suppression of the mitochondrial mutation of tetracycline resistance (Tr) is found. The suppressor mutation (i) is monogenous and recessive. Besides phenotypical suppression of mitochondrial resistance to tetracycline, it causes "the arrest" of the Tr plasmagene transmission. The effect of the suppressor is specific.
