AI Article Synopsis
- The study analyzed the peptidome of the adult cabbage root fly using MALDI-TOF MS, identifying over twenty neuropeptides from three tissue types: the brain/suboesophageal ganglion, retrocerebral complex, and thoracic-abdominal ganglion.
- Key peptides like allatostatins and corazonin were found in all three tissues, while adipokinetic hormone was exclusive to the retrocerebral complex.
- Notably, some neuropeptides found in other fly species were absent, marking the first detailed characterization of neuropeptides in Delia radicum.
Article Abstract
The peptidome of the central nervous system of adult cabbage root fly, Delia radicum (L) was investigated using matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS). Over twenty neuropeptides were identified from three different tissue sources, the combined brain/suboesophageal ganglion (SOG), the retrocerebral complex, and the thoracic-abdominal ganglion (TAG). A number of peptides were identified in all three tissues, including allatostatins, short neuropeptide F-like peptides, corazonin, a pyrokinin, and a myosuppressin. Adipokinetic hormone was restricted to the retrocerebral complex. Other peptides, including FMRFamides and sulfakinins were detected only in the brain/SOG and TAG. Some peptides, notably myoinhibitory peptides and tachykinins, which have been identified in other fly species, were not detected in any tissue sample. This study has structurally characterized for the first time, the neuropeptides from adult D. radicum.
