Figure 2. Absence of Ku86 reduces longevity of C. elegans in high NaCl, provided the exposure to high NaCl begins in the larval stage. C. elegans were placed on plates containing 50mM or 350 mM of NaCl beginning at the (A) adult stage (day 4 after hatching) or (B) L2/L3 larva stage (day 2 after hatching). Every two days worms were transferred to new plates to separate them from their progeny. Left panels: % of animals surviving. Right panels: average duration of life (mean ±SEM, * P < 0.05 relative to control (cku86+/+).
