Intragenic suppression at the b2 locus in Ascobolus immersus. I. Identification of three distinct groups of suppression.
نویسندگان
چکیده
A reversion study of EMS- or ICR170-induced ascospore color mutants in Ascobolus immersus is reported. Twenty-three new intragenic suppressors were isolated within the b2 locus. These are localized within three distinct groups on a genetic fine-structure map containing 21 identifiable sites. The pattern of reversion is discussed according to the known specificity of EMS and ICR170 in Ascobolus immersus.

INTRAGENIC SUPPRESSION AT THE b 2 LOCUS IN
The present report is a study of GO intragenic suppressors located in the A or E group of the b2 spore-color locus of Ascobolus immersus. The frameshift nature of the suppressors was shown by 19 combinations of plus and minus suppressor mutations. The location of the mutation sites on the genetic map of group A was defined. The conversion pattern ofi the frameshift suppressors is discussed acco...
متن کاملThe suppression of gene conversion and intragenic crossing over in Ascobolus immersus: evidence for modifiers acting in the heterozygous state.
Four distinct systems cv1, cv2, cv4 and cv6 behaving as monogenic factors have been found in the stock 28 of Ascobolus immersus. They each specifically suppress gene conversion in a spore pigmentation gene (respectively, b1, b2, b4 and b6). In the gene b2, where this phenomenon was studied in most detail, the effect of cv2 on the suppression of gene conversion is almost total; intragenic recomb...
متن کاملIsolation of the Ascobolus immersus spore color gene b2 and study in single cells of gene silencing by methylation induced premeiotically.
The ascomycete Ascobolus immersus has been extensively used as a model system for the genetic study of meiotic recombination. More recently, an epigenetic process, known as methylation induced premeiotically (MIP), that acts on duplicated sequences has been discovered in A. immersus and has raised a new interest in this fungus. To try and extend these studies, we have now cloned the A. immersus...
متن کاملDisparity of gene conversion in frameshift mutants located in locus b2 of Ascobolus immersus.
The frequency of conversion and the disparity in the direction of conversion were studied for six frameshift mutants lying in locus b2 of Ascobolus immersus and giving more 2 wild type:6 mutant (2+6m) than 6 wild type:2 mutant (6+2m) aberrant asci (type B). The frequency of conversion decreased from left to right in the locus. The disparity steadily increased from left to right and then reached...
متن کاملSuppression of crossing-over by DNA methylation in Ascobolus.
Homologous recombination between dispersed DNA repeats creates chromosomal rearrangements that are deleterious to the genome. The methylation associated with DNA repeats in many eukaryotes might serve to inhibit homologous recombination and play a role in preserving genome integrity. We have tested the hypothesis that DNA methylation suppresses meiotic recombination in the fungus Ascobolus imme...
