| Description | Disruption of the nuclear COX5 gene delayed senescence, increasing longevity between 7- and 15-fold in the 30 isolates tested (Dufour et al., 2000). Onset of senescence was not accompanied by the accumulation of senescence-specific mtDNA molecules (Dufour et al., 2000). |
|---|
| Gene Function | COX5 codes for subunit V of the cytochrome c oxidase complex (Dufour et al., 2000). |
|---|
| Other Phenotypes | Deletion of PaCOX5 results in exclusive use of the alternative respiratory pathway and a decrease in production of reactive oxygen species (Dufour et al., 2000). Moreover, accumulation of several senescence-specific mitochondrial DNA molecules is prevented in this nuclear mutant (Dufour et al., 2000) |
