Phenotypic Enhancement
A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
Circular minichromosomes become highly recombinogenic in topoisomerase-deficient yeast cells.
In topoisomerase-deficient yeast cells, we have found that circular minichromosomes are present as broad distributions of multimeric forms, which consist of tandemly repeated copies of their monomeric sequences. This phenomenon selectively occurs in Deltatop1 cells, and is highly magnified in double mutant Deltatop1 top2-4 cells. No multimers are observed in single mutant top2-4 or Deltatop3 cells, or in Deltatop1 cells ... [more]
