Abstract excerpt
Several observations suggest that developing ommatidia in the Drosophila eye have distinct dorsal-ventral (d-v) positional identities, despite their morphological uniformity. To identify molecular differences along the d-v axis of the eye, we carried out a systematic screen for P-element insertions that show nonuniform reporter gene expression along this axis. We identified P-element insertions in which lacZ...
