| ATG16 deletion | Under AL atg16 mutation shortens chronological, but not replicative lifespan. 0.5% glucose DR extends chronological lifespan of atg16 mutants, but amino-acid DR does not extend the short chronological lifespan of atg16 mutants (similar to several other autophagy mutants). ADE4 deletion in atg16 mutants results only in a partial extension of chronological lifespan by 0.5% glucose DR. The long chronological lifespan of tor1 mutants requires ATG16 [20421943]. | Yeast | — | — | — |

| ATH1 deletion | Deletion of ATH1 extend the mean chronological lifespan by 17% (at 30 degree Celsus in BY4742) [22783207].
ATH1 mutants have higher trehalose levels until the end of the post-diauxic growth phase, but reaches a plateau at the level of 50-70% of wild-type in the stationary phase [22783207]. | Yeast | +17 | — | — |
| Atm knockout | Atm-deficient mice are viable, retarded in growth, infertile (male produce no mature sperm and female no gametes), display neurological dysfunction, and exhibit severe defects in T cell maturation while going on to develop thymomas [8917548; 8689683]. The majority of mutant mice rapidly develop thymic lymphomas and die before 4 months of age [8843194].
Cells of Atm(-/-) mice exhibit slow growth also in culture and premature senescence, telomeres are extensively shortened in multiple tissues [8689683].
Mice mutant for Atm and Terc display progressive multi-organ system compromise and features of accelerated aging [12540856]. | Mouse | — | — | — |

| ATP2 Mutation | A temperature sensitive allele of ATP2 causes a clonal senescence phenotype resulting from the disruption of the age asymmetry between mother and daughter cells in that that daughter cells are born as old as they mother cells at 36 degree Celsius. This Mutation of valine to isoleucine at amino acid 90 does not affect growth on non-fermentable carbon source. This allele is associated with loss of mitochondrial membrane potential as well as failure to segregate functional mitochondria to daughter cells [12242224]. | Worm | — | — | — |
| Atr knockout | Deletion of Atr in young adults eliminates 80-90% of proliferating cells and results in several age-related phenotypes accompanied by a depletion of stem and progenitor cells and exhaustion of tissue renewal and homeostatic capacity [18371340].
Atr mutant mice (so called Seckle mice) exhibit high levels of replicative stress during embryogenesis, when proliferation is widespread, but this is reduced to marginal amounts in postnatal life. In spite of this decrease, adult Seckel mice display accelerated aging, which is further aggravated in the absence of p53. Seckel mice die in less than half a year, exhibit pancytopenia, cachexia and signs of premature aging, including hair graying, kyphosis, osteoporosis, accumulation of fat in the bone marrow, decreased density of hair follicles and thinner epidermis [19620979]. | Mouse | — | — | — |

| AVT1 deletion | Deletion of AVT1 accelerates the development of age-induced mitochondrial dysfunction without effecting the kinetics of vacuolar acidity decline and prevents the suppression of mitochondrial dysfunction by VMA1 and VPH2 overexpression without affecting vacuolar acidity. AVT1 deletion decreases mean, median and maximum lifespan by 21, 22, and 12%, respectively [23172144]. | Yeast | -20.6 | -22.4 | -11.8 |

| bar-1 mutation | BAR-1 may play a role in regulating daf-16 during dauer formation, particularly in conditions of oxidative stress as it directly interaction with DAF-16 and loss of bar-1 reduces activity of DAF-16 in dauer formation and lifespan. Deletion of bar-1 reduces mean (44%) and maximal (18%) lifespan, which is to a similar degree as seen to daf-16 mutants [15905404]. | Worm | -44 | — | -18 |
