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

<p>Ovarioles were hybridised with a riboprobe targeting <i>cad</i> RNA <b>(A-H)</b>, and a 25 h embryo stained with the same riboprobe <b>(I)</b>. Panels <b>C</b> and <b>E</b> show the reverse of ovarioles in panels <b>B</b> and <b>D</b> respectively. Red arrows in <b>F</b> indicate the nucleus, which aligns with the gap in the ‘horseshoe’ <b>(H-shoe)</b> localisation pattern. Green arrows in G and H point to a clearance in the front (‘toe’) of the ‘horseshoe’ shaped pattern, which is exactly opposite to the gap at the back (‘heel’) of the ‘horseshoe’ shape. All times after egg-laying (AEL). Scale bars 200 μm.
