Mutants of yeast sensitive to ultraviolet light.
Six uvr mutants of Saccharomyces cerevisiae with hypersensitivity to ultraviolet (UV) light were isolated after mutagen treatment with ethylmethanesulfonate. UV sensitivity ranges from moderate to extreme, and four of the mutants are also sensitive to nitrous acid. Ranking in terms of UV sensitivity does not parallel ranking in terms of nitrous acid sensitivity. Homozygous diploid mutant strain...
متن کاملMutants of yeast defective in mutation induced by ultraviolet light.
NDUCED mutations are thought to arise as a result of enzymatic processes uti‘lizing DNA damage as a substrate (BRIDGES 1969). Although the molecular mechanism is not known, evidence reviewed by WITKIN (1969) suggests that in E. coli mutations are produced during postreplication repair of lethal damage induced by ultraviolet light (UV) and controlled by r e d and ezrf (or lexf) genes. Strains ca...
متن کاملNew type of ultraviolet light-sensitive mutation in yeast.
Four temperature-sensitive ultraviolet light-sensitive mutants of yeast have been isolated. All four mutations show complementation in diploid cells and the phenotypes associated with the rad (ts) mutations are the result of the activities of single mendelian genes.
متن کاملUltraviolet radiation-sensitive mutants of Micrococcus lysodeikticus.
Micrococcus lysodeikticus strain ATCC 4698 was treated with N-methyl-N'-nitro-N-nitrosoguanidine (NTG) according to the method of E. A. Adelberg, M. Mandel, and G. C. C. Chen (Biochem. Biophys. Res. Commun. 18:88, 1965). Before and after exposure to 100 ,ug of NTG per ml in tris(hydroxymethyl)aminomethane-maleic buffer (TM), pH 6, cultures were plated on tryptone, yeast extract, and glucose med...
متن کاملUltraviolet-sensitive mutants in Neurospora crassa.
ADIATION-SENSITIVE mutants in bacteria have been reported repeatedly in recent years (s,ee SETLOW 1966). Several loci concerned with sensitivity have been mapped. Some of these mutants not only lacked the ability to repair damaged DNA but also failed to undergo genetic recombination (CLARK and MARGULIES 1965; HOWARD-FLANDERS and THERIOT 1966; VAN DE PUTTE et al. 1966). Among the eucaryotic orga...
