Transcriptome Profiling of Neurosensory Perception Genes in Wing Tissue of Two Evolutionary Distant Insect Orders: Diptera (Drosophila melanogaster) and Hemiptera (Acyrthosiphon pisum)

Abstract: The neurogenesis and neuronal functions in insect wing have been understudied mainly due to technical hindrances that have prevented electrophysiology studies for decades. The reason is that the nano-architecture of the wing chemosensory bristles hampers the receptors accessibility of odorants/tastants to receptors in fixed setup, whereas in nature, the wing flapping mixes these molecules in bristle lymph. In this report, we analyzed the transcriptome of the wing tissue of two species phylogenetically strongly… Show more

“…A yet unexplored field is the role of the glial cell in mature sensilla in Drosophila and in diverse insect orders in general, along with the functional dialog between the trichogen, tormogen, thecogen, and sensory neurons. In support of the present study, we have published recently a RNAseq analysis on adult wing tissue that shows the expression of most of the eight Innexin genes (Agnel, Rocha, & Robichon, ). More surprisingly, the adult wing Innexin transcripts range from moderate to elevated levels.…”

“…This highly enriched material in sensilla with very little cellular contaminants allowed us to explore the presence and roles of innexin proteins at the interface glial cell/neuron. The RNAseq data set analysis on adult wing tissue was carried out and published elsewhere (Agnel et al, ), which allowed us to assess the presence of trancripts of most of Innexin family members from moderate to elevated level (see Figure a for the RPKMs). The transcripts of Inx2 and Ogre were additionally confirmed by PCR (Figure a).…”

“…We note that many of the wing genes identified in our analysis, including both genes that are and are not enriched in chemosensory sensilla, were also recently identified in a different kind of RNA-seq comparison: between the entire wing of Drosophila and the wing and gut of a distantly related aphid, Acrytosiphon pisum [57]. In addition to a number of Obp , Che , and ppk genes, IR52a was among 12,188 genes found by that study to be expressed in the Drosophila wing, in agreement with our findings.…”
