Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.


Isolation and genetic analysis of extragenic suppressors of the hyper-deletion phenotype of the Saccharomyces cerevisiae hpr1 delta mutation.

Santos-Rosa H, Aguilera A

The HPR1 gene of Saccharomyces cerevisiae is involved in maintaining low levels of deletions between DNA repeats. To understand how deletions initiate in the absence of the Hpr1 protein and the mechanisms of recombination leading to deletions in S. cerevisiae, we have isolated mutations as suppressors of the hyper-deletion phenotype of the hpr1 delta mutation. The mutations defined five different ... [more]

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.
