Direct peptide profiling of the dorsal neural sheath of different Drosophila species. (ai-di) Thoracic portion containing FMRFa-like peptides. Note that peak intensity corresponds with isocopy number in the FMRFa prepropeptide. Small peaks corresponding to CAPA peptides from overlapping Va neurites are visible in D. virilis and D. mojavensis. (aii-dii) Abdominal portion containing CAPA peptides. Peaks corresponding to drosokinin and IPNa in D. pseudoobscura and D. sechellia represent contaminations with ganglionic neurites or the segmental nerve.
