Abstract
Neuropeptides and protein hormones are very important signaling molecules, and are involved in the regulation and coordination of various physiological processes in invertebrates and vertebrates. Using a bioinformatics approach, we screened the recently sequenced genome and six tissue-specific transcriptome databases (central nervous system, fat body, ovary, testes, male accessory glands, antennae) of the oriental fruit fly (Bactrocera dorsalis) that is economically one of the most important pest insects of tropical and subtropical fruit. Thirty-nine candidate genes were found to encode neuropeptides or protein hormones. These include most of the known insect neuropeptides and protein hormones, with the exception of adipokinetic hormone-corazonin-related peptide, allatropin, diuretic hormone 34, diuretic hormone 45, IMFamide, inotocin, and sex peptide. Our results showed the neuropeptides and protein hormones of Diptera insects appear to have a reduced repertoire compared to some other insects. Moreover, there are also differences between B. dorsalis and the super-model of Drosophila melanogaster. Interesting features of the oriental fruit fly are the absence of genes coding for sex peptide and the presence of neuroparsin and two genes coding neuropeptide F. The majority of the identified neuropeptides and protein hormones is present in the central nervous system, with only a limited number of these in the other tissues. Moreover, we predicted their physiological functions via comparing with data of FlyBase and FlyAtlas. Taken together, owing to the large number of identified peptides, this study can be used as a reference about structure, tissue distribution and physiological functions for comparative studies in other model and important pest insects.
