Temperature-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 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...
متن کاملGenetic Modification of a Temperature Sensitive Lethal in Drosophila Willistoni.
HE SURVIVAL value of a genetic factor is conditioned by its phenotypic Tmanifestation in all environments encountered by the species, as well as by its performance in combination with the rest of the genotype of the species. The hereditary norm of reaction can be analyzed by observing a given factor under various environmental conditions and in different genotypes. DOBZHANSKY and SPASSKY (1944)...
متن کاملProteomic Characterization of Inbreeding-Related Cold Sensitivity in Drosophila melanogaster
Inbreeding depression is a widespread phenomenon of central importance to agriculture, medicine, conservation biology and evolutionary biology. Although the population genetic principles of inbreeding depression are well understood, we know little about its functional genomic causes. To provide insight into the molecular interplay between intrinsic stress responses, inbreeding depression and te...
متن کاملTemperature-sensitive mutations of the notch locus in Drosophila melanogaster.
Temperature-conditional mutations of the Notch locus were characterized in an attempt to understand the organization of a "complex locus" and the control of its function in development. Among 21 newly induced Notch alleles, about one-half are temperature-conditional for some effects, and three are temperature-sensitive for viability. One temperature-sensitive lethal, l(1)Nts1, is functionally n...
