<i>npr-9(GF)</i> is not attracted to low concentrations of diacetyl.

<p>N2, <i>odr-10</i>, <i>glr-1</i> KD, <i>npr-9(LF)</i>, <i>npr-9(LF);glr-1</i> KD, and <i>npr-9(GF)</i> were assessed for chemotaxis to low concentration of diacetyl. Data are presented as mean +/- standard error (SE) with at least 50 animals assayed in three independent experiments analyzed via an unpaired two-tailed <i>t</i> test with Welsch’s correction. *** p < .001, significantly different from wild-type animals under identical conditions.</p>
