Figure 6


Fig. 6. sodC– cells were defective in chemotaxis. (A-C) Cells were challenged with a point source of either 0.1 µM or 10 µM cAMP. Tracing images of chemotaxing cells were arranged to demonstrate relative directional movement, cell shape and distances traveled towards the cAMP point source (circle). Superimposed tracing images were grouped as early (0 to 20 minutes) and late (21-40 minutes) duration as marked. Each tracing image is a 1-minute interval. (D) The roundness of chemotaxing cells is summarized as defined in the Materials and Methods.
