Photoreceptor neurons in the Drosophila retina are long (100 mu) and narrow, providing a system for the study of the intracellular distribution of transcripts and proteins. The chaoptic gene is expressed exclusively in photoreceptor neurons, and mutations of the gene result in reduced developmental competence of cells to generate normal rhabdomeric membranes. The mutant protein exhibited altered distribution both in developing and adult photoreceptor neurons. Furthermore, the transcript distribution in mutants was altered, decreasing with distance from the nucleus, instead of the normal uniform distribution throughout the cell soma. The deficit of transcript concentration correlated with the severity of developmental defect in rhabdomere formation along the cell. In contrast, the distribution of the opsin transcript was not affected by the chaoptic mutation. To observe RNA localization at the ultrastructural level, a high-resolution, electron microscopic in situ hybridization protocol was developed. The results indicate that the normal chaoptic transcript is present on the rough endoplasmic reticulum, which may be a vehicle for specific transcript distribution.
