RAS2 deletion | RAS2 deletion causes a 23% decrease in mean and a 30% decrease in maximum lifespan [8034612]. Deletion of RAS2 leads to a longer chronological lifespan [21076178]. Deletion of the RAS2 gene, which functions upstream of CYR1, doubles the mean chronological lifespan by a mechanism that requires Msn2/4 and Sod2 [12586694]. DR further extends chronological lifespan of ras2Delta [18225956]. | Yeast | -23 | — | -30 |
PDE2 Deletion | Deletion of PDE2 decreases mean replicative lifespan by 26% [11000115] and also results in a shorter chronological lifespan [21076178].

RIM15 deletion | RIM15 deletion results in 50% reduction of maximal chronological lifespan [11292860] and consistently decreases chronological lifespan under AL [21076178]. Rim15 is required for chronological lifespan extension caused by deficiency in RAS2, TOR1, or SCH9, as well as by 0.5% glucose restriction, but not by water starvation [18225956]. | Yeast | — | — | — |
SOD2 deletion | SOD2 deletion decreases replicative lifespan by 72% [17460215]. SOD2 deletion decreases chronological lifespan [21076178]. Deletion of SOD2 decreases chronological lifespan in wild-type and abolishes chronological lifespan extension in sch9Delta mutants as well as decreases chronological lifespan in cyr1:mTn mutants [12586694].
SOD2 deletion mutants are hypersensitive to oxygen and grow poorly in ethanol [10222047]. | Yeast | -72 | — | — |
HXK2 deletion | Deletion of HXK2 extends mean and maximum replicative lifespan by about 53% and 33%, respectively. Limiting glucose availability by mutating HXK2 significantly extends replicative lifespan and provides a genetically model of DR [11000115]. HXK2 deletion increases oxygene consumption. Changes in gene expression HXK2 mutation are quite similar to those of dietary-restricted cells. In fact, HXK2 mutants have a transcriptional profile that significantly resembles DR cells and cell overexpressing HAP4 [12124627]. | Yeast | +53 | — | +33 |
VPS21 deletion | Lack of VPS21 reduces lifespan under starvation conditions to a level similiar to that of wild-type cells incubated in synthetic complete medium and therefore blocked the lifespan-extending effect of DR [20657825]. | Yeast | — | — | — |
ATG7 deletion | ATG7 deletion reduces chronological lifespan by 70% [19302372]. | Yeast | — | — | — |

HES1 deletion | Deletion of HES1 (alias OSH5) extends mean replicative lifespan by 27% and is non-addative with moderate DR. Deletion of OSH5 delays different steps of endocytosis, a sterol-requireing process. [Xia et al., unpublished]. | Yeast | — | — | — |
INP53 deletion | Deletion of INP53 increases mean replicative lifespan by 31% [16293764]. INP53 deletion increases replicative lifespan by 31% in the alpha strain and by 10% in the a strain [18340043]. | Yeast | +31 | — | — |
ATG18 deletion | The replicative lifespan of ATG18 deletion mutant is not shorter than that of wild-type under DR [18690010]. | Yeast | — | — | — |
CKA2 deletion | CKA2 deletion approximately doubles mean chronological lifespan under starvation/extreme DR in BY4741 also increases as well as as heat-shock resistance in SDC medium in the W303-1A and DBY746 genetic backgrounds [20657825]. | Yeast | — | — | — |

VPS36 deletion | VPS36 deletion mutant had a chronological lifespan as long as wild type BY4741. Thus, Vps36 is not necessary for the starvation/extreme DR-dependent lifespan extension [20657825]. | Yeast | — | — | — |
CUP9 deletion | Deletion of CUP9 increases replicative lifespan by 30% in the alpha and a strains [18340043]. Although CPU9 was identified as a potential long-lived mutant strain in a bar-code screen, the chronological lifespan of CUP9 deletion mutant is not significantly different from than of wild-type under starvation/extreme DR [20657825]. | Yeast | — | — | — |

ACB1 deletion | ACB1 deletion extends chronological lifespan under starvation/extreme DR. Similar heat-shock resistance and resistance to a very hight concentration of acetic acid (but not resistance to oxidative stress) was enhanced by the deletion of ACB1. Deletion of ACB1 in W303-1A and DBY746 genetic backgrounds on synthetic complete media causes severe growth defects and sightly shorter lifespan and also heat-sensitivity [20657825]. | Yeast | — | — | — |
TRM9 deletion | TRM9 deletion almost triples mean chronological lifespan under starvation/extreme DR, increases heat resistance, but reduces resistance to acetic acid. Similar effect were present in the BY746 background in SDC medium [20657825]. | Yeast | — | — | — |
RPL12B deletion | Deletion of RPL12B increases mean replicative lifespan by 20% in the alpha strain [18423200] and by 22% in the remade strain, but increases non-significantly the mean replicative lifespan by 13% in the ORF collection [22377630]. RPL12B mutation promotes mean chronological longevity extension and heat-shock resistance but reduces acetic acid resistance under starvation/extreme DR. In DBY746 mutation of RPL12B almost doubles mean chronological lifespan in SDC medium and increases heat-shock resistance [20657825] | Yeast | — | — | — |
ARO7 deletion | Under starvation/extreme DR deletion of ARO7 increases mean chronological lifespan and confers higher resistance to heat-shock, but made cell more sensitive to acetic acid and leads to growth defects.
