Novel Pseudotaxis Mechanisms Improve Migration of Straight-Swimming Bacterial Mutants Through a Porous Environment

ABSTRACT Bacterial locomotion driven by flagella is given directionality by the chemotaxis signal transduction network.In the classic plate assays of migration in porous motility agar, efficient motility is compromised in chemotaxis mutants of diverse bacteria.Nonchemotactic mutants become trapped within the agar matrix.Suppressor mutations that pr
