Model of single-cell motility. (A) Wild-type and taxD1 cells move equally in all directions in the dark. (B) Incident light from the top of the figure induces wild-type cells to take more steps toward the light than away from the light, whereas taxD1 cells also take more steps perpendicular to the light. Across all cases, the distribution of step sizes is essentially the same; instead, the distribution of step angles is affected.
