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

Combination of the loss of cmnm5U34 with the lack of s2U34 modifications of tRNALys, tRNAGlu, and tRNAGln altered mitochondrial biogenesis and respiration.

Wang X, Yan Q, Guan MX

Yeast Saccharomyces cerevisiae MTO2, MTO1, and MSS1 genes encoded highly conserved tRNA modifying enzymes for the biosynthesis of carboxymethylaminomethyl (cmnm)(5)s(2)U(34) in mitochondrial tRNA(Lys), tRNA(Glu), and tRNA(Gln). In fact, Mto1p and Mss1p are involved in the biosynthesis of the cmnm(5) group (cmnm(5)U(34)), while Mto2p is responsible for the 2-thiouridylation (s(2)U(34)) of these tRNAs. Previous studies showed that partial modifications at U(34) ... [more]

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
