Conserved regions driving expression in DVA.

<p>Panels <b>A–D</b> are photomicrographs of the tail region of transgenic L4-adult <i>C. elegans</i>. DVA expression is denoted by a yellow line identifying the DVA neuron. The gene name is followed by the conserved region numbered by its position relative to the first exon. <b>A</b>. DVA expression of the 190 bp conserved region 2 of <i>nmr-1</i> (nmr-1.cs2). <b>B</b>. DVA expression of the 308 bp fragment containing conserved region 1 of <i>twk-16</i> (twk-16.cs1). <b>C</b>. DVA expression of the 180 bp conserved region 3 of <i>fax-1</i> (fax-1.cs3). <b>D</b>. DVA expression of the 322 bp conserved region 4 of <i>fax-1</i> (fax-1.cs4). Scale bar = 20 µm.
