Suppressors of yeast actin mutations.
Suppressors of a temperature-sensitive mutation (act1-1) in the single actin gene of Saccharomyces cerevisiae were selected that had simultaneously acquired a cold-sensitive growth phenotype. Five genes, called SAC (suppressor of actin) were defined by complementation tests; both suppression and cold-sensitive phenotypes were recessive. Three of the genes (SAC1, SAC2 and SAC3) were subjected to...
متن کاملMutations in the SAC1 gene suppress defects in yeast Golgi and yeast actin function
The budding mode of Saccharomyces cerevisiae cell growth demands that a high degree of secretory polarity be established and directed toward the emerging bud. We report here our demonstration that mutations in SAC1, a gene identified by virtue of its allele-specific genetic interactions with yeast actin defects, were also capable of suppressing sec14 lethalities associated with yeast Golgi defe...
متن کاملSuppressors of recB mutations in Salmonella typhimurium.
Using a screen that directly assesses transductional proficiency, we have isolated suppressors of recB mutations in Salmonella typhimurium. The alleles of sbcB reported here are phenotypically distinct from those isolated in Escherichia coli in that they restore recombination proficiency (Rec+), resistance to ultraviolet light (UVR), and mitomycin C resistance (MCR) in the absence of an accompa...
متن کاملTemperature-sensitive nonsense suppressors in yeast.
A single mutation leads to temperature-sensitive amber and ochre suppression in yeast. This mutation maps in or near the SUP4 gene on chromosome X.
متن کاملRecessive lethal amber suppressors in yeast.
Recessive lethal amber suppressor mutations have been isolated in a diploid strain of Saccharomyces cerevisiae. Diploids carrying these suppressors upon sporulation yield asci with only two live spores, both lacking the suppressor. At least two classes of recessive lethal suppressors exist. Aneuploid strains carrying one wild type and one suppressor locus have been isolated and used in mapping ...
