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.

Isolation of type I and II DNA topoisomerase mutants from fission yeast: single and double mutants show different phenotypes in cell growth and chromatin organization.
We have isolated mutants defective in DNA topoisomerases and an endonuclease from the fission yeast Schizosaccharomyces pombe by screening individual extracts of mutagenized cells. Two type I topoisomerase mutants (top1) and three endonuclease mutants (end1) were all viable. The double mutant top1 end1 was also viable and, in its extract, Mg2+- and ATP- dependent type II activity could be detected. ... [more]
