<i>orb2</i> autoregulates the localization and translation of <i>orb2</i> mRNA.

<p>A) Wild type spermatid cyst showing that Orb2 protein (red) and <i>orb2</i> mRNA (green) are distributed in the characteristic comet pattern and display extensive co-localization, particularly in the comet head. B) In <i>orb2^ΔQ</i> spermatids that elongate in the incorrect direction, Orb2^ΔQ protein (red) and <i>orb2^ΔQ</i> mRNA (green) are distributed uniformly in the cyst and there is no evidence of a comet head (expected position is indicated by arrow). All images are orientated with apical to the left and basal to the right. Scale bar: 20 µm.
