Genetic analysis of temperature-sensitive lethal mutants of Salmonella typhimurium.
We have isolated 440 mutants of Salmonella typhimurium that show temperature-sensitive growth on complex medium at 44 degrees. Approximately 16% of the mutations in these strains have been mapped to 17 chromosomal locations; two of these chromosomal locations seem to include several essential genes. Genetic analysis of the mutations suggests that the collection saturates the genes readily mutab...
متن کاملTemperature-sensitive cell-lethal mutants of drosophila: isolation and characterization.
One hundred and twenty-one sensitive (ts) sex-linked lethals were screened by means of X-ray-induced somatic crossing over to determine if any were ts cell-lethal mutants. Cell-lethal mutations were identified by their ability to block the development of homozygous clones when raised under restrictive conditions (29degrees). Twenty-two ts cell-lethal mutants were isolated and categorized into t...
متن کاملInvestigation of Mutation in Chitinase Gene in Gamma Radiated Mutants of Trichoderma Harzianum by STS Marker
Effects of induced mutation via gamma irradiated with 250 Gy dose (in Nuclear Agriculture Research School- Nuclear Science and Technology Research Institute) on Trichoderma harzianum conidiaon chitinase activity by STS molecular marker have been evaluated in this study. Among 20 irradiated mutants which selected via improved antagonistic capability against Rhizoctonia sola...

متن کاملMutual correction of faulty PCNA subunits in temperature-sensitive lethal mus209 mutants of Drosophila melanogaster.
Proliferating cell nuclear antigen (PCNA) functions in DNA replication as a processivity factor for polymerases delta and epsilon, and in multiple DNA repair processes. We describe two temperature-sensitive lethal alleles (mus209(B1) and mus209(2735)) of the Drosophila PCNA gene that, at temperatures permissive for growth, result in hypersensitivity to DNA-damaging agents, suppression of positi...
