Abstract: | "During the past decade, antennal transcriptome sequencing has been applied to at least 50 species from 16 families of the Lepidoptera order of insects, emphasizing the identification and characterization of chemosensory-related genes. However, little is known about the chemosensory genes in the Zygaenidae family of Lepidoptera. Herein, we report the transmembrane protein gene repertoires involved in chemoreception from Achelura yunnanensis (Lepidoptera: Zygaenidae) through transcriptome sequencing, bioinformatics, phylogenetics and polymerase chain reaction (PCR) approaches. Transcriptome analysis led to the generation of 555.47 million clean reads and accumulation of 83.30 gigabases of data. From this transcriptome, 132 transcripts encoding 69 odorant receptors (ORs), 33 gustatory receptors (GRs), 26 ionotropic receptors (IRs), and four sensory neuron membrane proteins (SNMPs) were identified, 69 of which were full-length sequences. Notably, the number of SNMPs in A. yunnanensis was the largest set in Lepidoptera to date. Phylogenetic analysis combined with sequence homology highlighted several conserved groups of chemoreceptors, including pheromone receptors (a so-called pheromone receptor (PR) clade: AyunOR50 and novel PR members: AyunOR39 and OR40), a phenylacetaldehyde-sensing OR (AyunOR28), carbon dioxide receptors (AyunGR1-3), and antennal IRs (13 A-IRs). In addition, a Zygaenidae-specific OR expansion was observed, including 15 A. yunnanensis members. Expression profiles revealed 99 detectable chemosensory genes in the antennae and 20 in the reproductive tissues, some of which displayed a sex-biased expression. This study identifies potential olfactory molecular candidates for sensing sex pheromones, phenylacetaldehyde or other odorants, and provides preliminary evidence for the putative reproductive function of chemosensory membrane protein genes in A. yunnanensis" |
