Figure 6.Sch9p is the downstream mediator of TOR-dependent decreases in ROS level and chronological life span extension. Analysis of cellular ROS and
chronological life span in the same strains shown in Figure 5. (A)
FACS analysis of day 2 stationary phase cells stained for cellular
superoxide using dihyroethidium (DHE) is shown. The mean fluorescence
intensity is plotted +/- one standard deviation (** represents a p-value
<0.01 according to a student's t-test). (B) Chronological life
span plotted as described in Figure 4B.
