FIG. 4.
Neither iron nor ROS accumulation provoked by Aft1 misregulation causes the actin cytoskeleton disorganization observed in the grx3 grx4 double mutant. (A) Actin staining of samples from the wild-type and grx3 grx4 and grx3 grx4 aft1 mutant cultures either treated, or not treated, with 1 mM hydrogen peroxide. (B) Quantification of the experiment shown in panel A. wt, wild type.
