Observations

The budding yeast suffers from clonal or replicative senescence in which each mother cell can only divide a limited amount of times to produce daughter cells; the number of divisions by the mother cell is thus used to determine lifespan. The accumulation of extrachromosomal ribosomal DNA circles has been suggested as a possible causal mechanism of replicative senescence [0045]. It is also possible to measure chronological lifespan in yeast in terms of stationary phase survival; that is, the survival of individual cells in a non-dividing state. Longevity varies considerably between strains and various manipulations, including caloric restriction which in yeast consists of reducing the glucose level, increase lifespan [0981].

Several genes have been identified that regulate clonal senescence or chronological lifespan [0056], but because these two measurements are fundamentally different some genes have been shown to have opposite effects on them [0746].
