    BRE5 deletion Deletion of BRE5 increases mean replicative lifespan by 30% [16293764] and mean chronological lifespan in diploid cells [21447998] Yeast +30
    CCR4 deletion Deletion of CCR4 increases mean chronological lifespan by 20 - 41% (20, 33, 41) in diploid cells [21447998]. In W303R CCR4 deletion shortens replicative lifespan by approximately 80% and results in temperature sensitivity that is suppressed by SSD1-V. SSD1-V partially suppresses the short-lifespan of ccr4 mutant. CCR4 mutation is synthetically lethal in combination with deletion of MPT5 in the absence of SSD1-V [11805047]. Yeast -80 to +20
    CDC25 mutation The CDC25-10 allele extends mean and maximum replicative lifespan by 34% and 18%, respectively, at 30 degree Celsius. cdc25-10 mutants have an extended replicative lifespan under AL. Growth on 0.5% glucose restriction does not further extend replicative lifespan of cdc25-10 mutants. CDC25 null mutant is not viable. CDC25 appears to act in the same genetic pathway as SIR2 and NPT1 and is suggested to be genetic model of DR [11000115]. Yeast +34 +18
    CDC6 mutation The CDC6-1 conditional allele results in an approximately 20% increase in mean replicative life span. This allele is defective for replicative initiation form the rDNA ARS at 27 degree Celsius, resulting in a reduced rate of extrachromosomal rDNA circle accumulation [9428525]. The cdc6-1 allele results in genomic instability at the permissive temperature [8552037]. Yeast +20
    HPR1 deletion Deletion of HPR1 decreases replicative lifespan [11756539] Yeast
    Transient CDC7 inactivation Transient inactivation of CDC7 results in a shortened replicative lifespan [2698814]. Yeast
    CIT2 deletion Deletion of CIT2 has no effect on replicative lifespan [10224252]. Yeast
    CIT2 overexpression Overexpression of CIT2 has no effect on replicative lifespan [10224252]. Yeast
    COQ3 deletion Deletion of COQ3 decreases chronological lifespan and renders cells respiratory deficient and sensitive to hydrogen peroxide [12586694]. Yeast
    CPR7 deletion Deletion of CPR7 has no effect on lifespan replicative lifespan, but increases chronological lifespan [11361336] Yeast
    CTF4 deletion Deletion of CTF4 results in an approximately 75% reduced mean replicative lifespan [12024027]. Yeast
    CYT1 deletion Deletion of CYT1 increases replicative lifespan by 15% in the alpha strain and decreases replicative lifespan by 20% in a strain. Deletion of CYT1 decreases replicative lifespan and cancels out replicative lifespan extension by HAP4 overexpression. Initially, it was shown that deletion of CYT1 also prevents lifespan extension by 0.5% glucose restriction [12124627], but later it was shown that either 0.5 or 0.05 % glucose restriction increases replicative lifespan of cyt1Delta cells [16311627]. Yeast
    DNA2 deletion Mutants in DNA2 exhibit an accelerated ageing phenotype including extended cell cycle time, age-related transcriptional silencing defects, and nucleolar reorganization, which are all phenotypes of old wild-type cells. Lifespan of DNA2 mutants is extended by expression of an additional copy of SIR2 or by deletion of FOB1 and therefore the lifespan shortening partially suppressed. Three different alleles of DNA2 (dna2-1, dna2-2, and dna2-20) result in a significant shortened lifespan up to 85%. DNA2 mutation shorten the already short lifespan of SGS1 mutants [12024027]. Yeast
    DNL4 deletion DNL4 deletion does not affect lifespan [10521401], although it renders cells defective for non-homologous end-joining [9242411] Yeast
    FOB1 deletion Mutation in FOB1 extends replicative lifespan by 30-50% [10230397]. FOB1 mutation increases replicative lifespan by 25% in the alpha strain and by 10% in a strain [19030232]. FOB1 mutant exhibit an about 20% mean replicative lifespan increase [15722108]. Deletion of FOB1 causes extension in the short life span of the sir2 mutant by around 50% [10521401]. Mutation of the FOB1 gene slows the generation of rDNA circles and thus extends life span by approximately 30% in W303 and 50% in K2307 [10230397]. Even in cells lacking both Sir2 and Fob1, nicotinamide prevents the lifespan extension by DR [16311627]. Yeast
    GAL83 deletion Deletion of GAL83 has no effect on replicative lifespan in S228C [10921902] and general GAL83 mutants have no obvious phenotype [10990457]. Yeast
    GPA2 deletion Deletion of GPA2 increases mean and maximum replicative lifespan by 40% and 26%, respectively. GPA2 deletion extends replicative lifespan by reducing cAMP-PKA activity and provides a genetic model for DR [11000115]. Yeast +40 +26
    GPD1 deletion GPD1 deletion shortens replicative lifespan by 25% and prevents lifespan extension by high osmolarity [12391171]. Yeast +25
    GPR1 deletion Deletion of GRP1 increases mean and maximum replicative lifespan by 41% and 26%, respectively. GRP1 deletion mutants have also longer chronological lifespan. Deletion of GPR1 extends replicative lifespan by reducing cAMP-PKA activity and provides a genetically model for DR [11000115]. Yeast +41 +26
    HAP4 overexpression Overexpression of HAP4 from the ADH1 promoter extends lifespan of PSY316 strain approximately 40% under growth conditions favoring fermentation (2% glucose). Overexpression of HAP4 increases replicative lifespan, but is non-additive with 0.5% glucose restriction in lifespan extension. Lifespan extension by HAP4 overexpression requires SIR2 [12124627]. HAP4 deletion suppresses replicative lifespan extension to 30% and 33% on 0.1% glucose and on elimination of non-essential amino acids, respectively [20178842]. HAP4 overexpressing cells demonstrate a transcriptional response resembling cells undergoing diauxic shift, consume more oxygen, and exhibit increased Sir2-dependent transcriptional silencing at telomeres and rDNA [12124627]. Yeast +30 to +40
    HAP5 deletion Deletion of HAP5 shortens replicative lifespan by approximately 40%. This is not a premature aging phenotype as "old" HAP5 cells do not become premature sterile or exhibit other biomarkers of yeast aging [9271578]. HAP5 null mutants are unable to grow on a non-fermentable carbon source [7828851]. Yeast -40
    HDA1 deletion Deletion of HDA1 has no effect on longevity under AL, but acts synergistically with 0.1% glucose restriction to increase replicative lifespan [12213553]. Deletion of HDA1 leads to a slightly increased chronological lifespan [19801973]. Deletion of HDA1 has no effect on the wild-type lifespan in the short-lifespan of YSK771 strain, but suppresses the short-lifespan of SIR3 mutants [10512855]. Null mutation results in increased telomeric silencing and increased histone acetylation [8962081]. Yeast
    YKU70 deletion Deletion fo YKU70 shortens lifespan, but does not accelerate the normal aging process [10521401]. YKU70 null mutants are defective for non-homologous end-joining [8754818] and for telomeric silencing [9635192]. Yeast
    YKU80 deletion Deletion of YKU80 shortens replicative lifespan, but does not accelerate the normal aging process [10521401]. YKU80 null mutant is defective for non-homologous end-joining [8754818] and for telomere silincing [9501103; 9635192] Yeast
    HOG1 deletion Deletion of HOG1 shortens replicative lifespan by 25% and prevents lifespan extension by high osmolarity [12391171]. HOG1 deletion slightly decreases chronological lifespan and partially suppresses the premature aging phenotype and short lifespan of ISC1 deletion [22445853]. Yeast -25
