<i>orthodenticle</i> transcript localisation in <i>Pararge aegeria</i> oocytes.

<p>Ovarioles were hybridised with a riboprobe targeting <i>otd</i> RNA <b>(A-H)</b>. For comparison purposes <i>cad</i> localisation in an oocyte of a similar stage to <b>H</b> is also shown in panel <b>I</b>. Transcripts for <i>otd</i> localise to 2 distinct domains; an anterior domain <b>(halo)</b> lining the nurse cell-oocyte boundary and a more posterior domain <b>(crown)</b>; a narrow band that breaks after curving posteriorly on one face. Panels <b>C</b> and <b>E</b> depict the back view of the ovarioles in panels <b>B</b> and <b>D</b> respectively. All ovarioles are oriented in such a way that the AP axis in maturing oocytes is depicted top to bottom (i.e. anterior of oocyte is bordering the nurse cells). Scale bars 200 μm.
