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 کاملArabidopsis thaliana mutants altered in homologous recombination.
Homologous recombination contributes both to the generation of allelic diversity and to the preservation of genetic information. In plants, a lack of suitable experimental material has prevented studies of the regulatory and enzymatic aspects of recombination in somatic and meiotic cells. We have isolated nine Arabidopsis thaliana mutants hypersensitive to x-ray irradiation (xrs) and examined t...
متن کاملThymineless death in recombination deficient mutants of Escherichia coli K12.
When grown in thymine-free minimal synthetic medium, thyA recA mutants of Escherichia coli K12 were comparatively more resistant and thyA recBC mutants more sensitive to thymineless death (TLD) than their respective parent strains. No excessive numbers of single-strand breaks were observed in the DNA of the recBC mutant strain starved for thymine, hence the hypersensitivity for TLD in this stra...
متن کاملGenetic characterization of recombination-deficient mutants of Bacillus subtilis.
Recombination-deficient (rec), radiation-sensitive mutations in Bacillus subtilis are grouped in at least seven distinct loci. Map positions are determined for six of these loci.
متن کاملRecombination-deficient Streptococcus sanguis.
A UV-sensitive derivative was obtained from Streptococcus sanguis Challis. The organism could be transformed with a number of small streptococcal plasmids at frequencies equal to, or 1 logarithm below, the transformation frequencies for the parent organism. However, transformation with chromosomal DNA was greatly impaired in the UV-sensitive derivative.
