Phenotypic Suppression
A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
Repeat expansion in the budding yeast ribosomal DNA can occur independently of the canonical homologous recombination machinery.
Major eukaryotic genomic elements, including the ribosomal DNA (rDNA), are composed of repeated sequences with well-defined copy numbers that must be maintained by regulated recombination. Although mechanisms that instigate rDNA recombination have been identified, none are directional and they therefore cannot explain precise repeat number control. Here, we show that yeast lacking histone chaperone Asf1 undergo reproducible rDNA repeat expansions. ... [more]
Throughput
- Low Throughput
Ontology Terms

Additional Notes
- deletion of rad52 causes accumulation of shorter deleted rDNA alleles than seen in an asf1 single mutant
