Cover: A third instar Drosophila eye antennal disc in which the homeobox transcription factor Sine oculis has induced the formation of an ectopic eye within the antennal field by repressing transcription of the antennal/head capsule selector gene cut. Photoreceptors in the normal (blue) and ectopic (orange) eye fields are shown; purple, F-actin. See Research article by Anderson et al. on p. 991.
