<i>tbh-1</i>, <i>ser-3</i>, and <i>crh-1</i> suppress <i>cat-2</i>.

<p>Double mutants for <i>cat-2</i> and <i>tbh-1</i> (A), <i>ser-3</i> (B), or <i>crh-1</i> (C) were examined for paralysis on NGM plates containing 1 mM aldicarb. (D-F) The time required for 50% of the animals to become paralyzed was determined using Prism. <i>tbh-1</i>, <i>ser-3</i>, and <i>crh-1</i> single mutants exhibited similar aldicarb sensitivity to wild-type N2 animals. The aldicarb resistance observed in the <i>cat-2</i> mutant was significantly reduced in the <i>cat-2;tbh-1</i>, <i>cat-2;ser-3</i>, and <i>cat-2,crh-1</i> double mutants. *P<0.001 by the Tukey-Kramer multiple comparison test.
