Fig 3. BIR does not fully account for the role of Rad52 in preventing accelerated senescence.

Senescence rates were measured by serial passaging est2Δ, est2Δ pol32Δ, and est2Δ rad52Δ strains (derived from the sporulation of CCY155) in liquid culture. Cell density was measured each day after 24 h of growth in liquid culture, followed by dilution to 2 x 10⁵ cells/ml. Mean ± SE for five independent spore isolates for est2Δ and ten isolates for both est2Δ pol32Δ and est2Δ rad52Δ is shown.
