Chemotactic response was measured as the formation of haloes on minimal medium soft agar plate plus 10 mM tested compound. Symbols: +, strong chemotactic response; +/−, weak chemotactic response; −, no detectable chemotactic response as determined by halo sizes. ND, not determined, because UW386 formed irregular star-like halo shapes on these soft agar plates.
