The actin cytoskeleton is required for elevated catalase activity and the purging of peroxide in the yeast progeny. (A) Catalase activity in mother (M) and daughter (D) cells upon transient depolymerization of F-actin during cytokinesis [with latrunculin A (LatA +)] or under normal conditions [without latrunculin A (LatA −)]. (B) Hydrogen peroxide levels in mother and daughter cells treated as in A. Values are normalized relative to WT mother cells, which were arbitrarily set to 1. Error bars refer to the SD of the mean.
