Deletion results in mutants with a 2-fold decrease in mean and maximum chronological lifespan under conditions of nutrient depletion [17710147]. Mutation of RAD9 shortens lifespan by 30% in DBY747 [7806576] and in strain W303 [11290710].
RAD9 mutation has no effect on telomeric silencing or length [10924458].
Mean: -30
