    SCH9 Deletion SCH9 deletion increases chronological lifespan by up to threefold. Stress-resistance transcription factors Msn2/Msn4 and protein kinase Rim15 are required for this life-extension. Deletion of the mitochondrial antioxidant enzyme superoxide dismutase gene SOD2 prevents the increased chronological lifespan caused by SCH9 deletion [11292860]. Mutations that decrease the activity of the Ras/Cyr1/PKA pathway also extend longevity and increase stress resistance by activating transcription factors Msn2/Msn4 and Sod2 [12855292]. SCH9 deletion mutants exhibit more than 3-fold extension of chronological lifespan. By day 9 of medium depletion all the wild-type cells were dead while 50% sch9 mutants survived [17710147]. Deletion of SCH9 also increases resistance to heat shock and oxidative stress [11292860], and increases replicative lifespan by 18% (in DBY746) [12586694]. SCH9 deletion increases the replicative lifespan by 40% in the alpha strain [18340043] and increases mean chronological lifespan by 97 - 246% (97, 133, 154, 226, 246) in diploid cells [21447998]. Mutation or deletion of SCH9 increases resistance to oxidants and extends chronological lifespan [11292860; 16286010]. The extended lifespan of SCH9 deletion mutants is not further extended by low glucose DR and is independent of Sir2 [16293764]. Deletion of RIM15 or GIS1 reverses chronological lifespan extension associated with sch9Delta. Water restriction further increases chronological lifespan of sch9Delta [18225956]. Deletion of SCH9 results in a longer chronological lifespan [21076178]. Yeast +18 to +300
    TOR1 Deletion TOR1 deletion extends mean and maximum replicative lifespan by 21 and 25% [16293764] as well as chronological lifespan [21076178]. This lifespan extension is independent of SIR2 and additive with deletion of FOB1 [16293764]. Deletion of TOR1 fails to increase the replicative lifespan of a sir2 mutant [20947565]. Deletion of TOR1 substantially extends chronological lifespan, increasing median survival almost 3-fold (wild-type 4.5 days, tor1 null 12 days), i.e. by 167%. By 21 days in culture, the vast majority of wild-type cells had died (>99.9%), whereas many tor1 null cells remained viable. Deletion of TOR1 also extends the chronological lifespan of the relatively short-lived BY4742 strain, one of the two haploid genetic backgrounds of the widely used Yeast Knockout Collection available from Open Biosystems. Deletion of TOR1 fails to extend chronological lifespan in Petite strains that are unable to respire [17403371]. TOR1 deletion increases replicative lifespan by 30% in the alpha strain and 20% in a strain [19030232]. TOR1 deletion mutant have and increased mean and maximum replicative lifespan by 21% and 6%, respectively [21931558]. Deletion of TOR1 extends replicative lifespan as well as chronological lifespan [21076178] and glucose restriction fails to further extend the long replicative lifespan of tor1Delta [16293764; 16418483; 18225956]. Water starvation (extreme DR) further extends chronological lifespan of tor1 mutants [18225956]. Yeast +21 to +30 +167 +6 to +25
    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]. PDE2 null mutant are sensitive to oxidative stress [10394911]. Yeast -26
    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
    VPS8 deletion Lack of VPS8 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
    VPS27 deletion Under starvation conditions VPS27 deletion mutants have a dramatically reduced lifespan [20953148]. Yeast
    SAM1 deletion Deletion of SAM1 increases replicative lifespan by 20% in the alpha strain and 15% in the a strain [18340043]. Yeast +15 to +20
    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
    CKB2 deletion Lack of Ckb2 promotes a modest but significant chronological lifespan extension and marked increase in yeat resistance [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
    APD1 deletion Although APD1 was identified as a potential long-lived mutant strain in a bar-code screen, deletion of APD1 does not significantly affect chronological lifespan under starvation/extreme DR [20657825]. Yeast
    ZTA1 deletion Deletion of ZTA1 increases replicative lifespan by 15% in the alpha strain and decreased by 10% in the a strain [18340043]. Although ZTA1 was identified as a potential long-lived mutant strain in a bar-code screen, deletion of ZTA1 does not significantly affect chronological lifespan under starvation/extreme DR [20657825]. Yeast
    SSN2 deletion Although SSN2 was identified as a potential long-lived mutant strain in a bar-code screen, deletion of SSN2 does not significantly affect chronological lifespan 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
