Transcription of TIM9, a new factor required for the petite-positive phenotype of Saccharomyces cerevisiae, is defective in spt7 mutants

Abstract

TIM9 has been identified as an additional novel gene required for the petite-positive phenotype in Saccharomyces cerevisiae. tim9-1 was obtained through a screen for respiratory-deficient strains that are unable to survive in the absence of mitochondrial
