Intragenic mapping of chemically induced ad-7 mutants of Schizosaccharomyces pombe.
نویسنده
چکیده
Thirty adenine-requiring ad-7 mutants of Schizosaccharomyces pombe, induced by ethylmethanesulfonate, methyl-methanesulfonate, and hydroxylamine and exhibiting low spontaneous reversion frequencies, were located by intragenic recombination analysis. Their identification as ad-7 mutants was assessed in relation to two previously mapped ad-7 mutants. Each mutant was found to occupy a distinct mutational site; the smallest recombination fraction observed between the two closest mutational sites was of the order of 0.5 x 10(-6).

Meiotic recombination-deficient mutants of Schizosaccharomyces pombe.
A mutant screen employing the ade6-M26 recombination hotspot was developed and used to isolate Schizosaccharomyces pombe mutants deficient in meiotic recombination. Nine rec mutations were recessive, defining six complementation groups, and reduced ade6 meiotic recombination 3-fold to greater than or equal to 300-fold when homozygous. Three recessive rec mutations analyzed further also reduced ...
متن کاملSuppression by methionine of reversions to adenine independence in Schizosaccharomyces pombe.
Spontaneous mutations, and those induced by nitrous acid or ultraviolet light, were studied in the haploid fission yeast Schizosaccharomyces pombe. Reverse mutations conferring ability to grow on a minimal medium lacking adenine were scored in adenine auxotrophs, and in di-auxotrophs having requirements for both adenine and methionine. The apparently lower mutability of the ad-1 mutants in the ...
متن کاملFive RecA-like proteins of Schizosaccharomyces pombe are involved in meiotic recombination.
The genome of Schizosaccharomyces pombe contains five genes that code for proteins with sequence similarity to the Escherichia coli recombination protein RecA: rad51+, rhp55+, rhp57+, rlp1+, and dmc1+. We analyzed the effect of deletion of each of these genes on meiotic recombination and viability of spores. Meiotic recombination levels were different from wild type in all recA-related mutants ...
متن کاملAllelic Complementation at the Adenylosuccinase Locus in Schizosaccharomyces Pombe.
OMPLEMENTATION between allelic mutants at the ad-4 (adenine-4) locus, deficient for the enzyme adenylosuccinase (adenylosuccinate AMP-lyase, C.E. 4322). was first reported in Neurospora (GILES, PARTRIDGE and NELSON 1957; WOODWARD, PARTRIDGE and GILES 1958). It was found that certain pairs of these mutants, which as a result of the absence of adenylosuccinase activity require adenine for growth,...
متن کاملNonrandom homolog segregation at meiosis I in Schizosaccharomyces pombe mutants lacking recombination.
Physical connection between homologous chromosomes is normally required for their proper segregation to opposite poles at the first meiotic division (MI). This connection is generally provided by the combination of reciprocal recombination and sister-chromatid cohesion. In the absence of meiotic recombination, homologs are predicted to segregate randomly at MI. Here we demonstrate that in rec12...
