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
Deficiency in both type I and type II DNA topoisomerase activities differentially affect rRNA and ribosomal protein synthesis in Schizosaccharomyces pombe.
The synthesis of rRNA and r-proteins was studied in temperature-sensitive topoisomerase mutants of the fisson yeast Schizosaccharomyces pombe. To reduce the severity of heatshock response seen in the wild type strain, slow temperature shift-up of the cultures was used to inactivate the mutant topoisomerases. It was found that the temperature shift caused a large preferential reduction of rRNA synthesis in ... [more]
