Glutamate is a key regulator of omega turns.

<p>N2, <i>glr-1(LF)</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 tested for the frequency of reversals that terminate with an omega turn during off food conditions Data are presented as mean +/- standard error (SE) with at least 5 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>
