A deeper look into the morphology and receptors found in the tick (Acari: Ixodidae) chemoperception structure, the Haller's organ
… focused on the expression of ionotropic (IR) and gustatory receptors (GR) in the forelegs of male and female ticks. Additionally, two phylogenetic trees were created corresponding to each receptor type. The phylogenetic trees show the orthology between the tick ionotropic and gustatory receptors …

Mosquito Odorant Receptors: C-terminal Motifs, Subfamily Expansion, and Function
… signaling components such as mosquito odorant receptors. This hypothesis is supported by several lines of evidence including the highly divergent and lineage-specific nature of this receptor family. Likely these differences are subtle and will be identified in highly focused studies. Even …

Functional characterization of olfactory receptors and molecular species identification of vector mosquitoes.
… that are embedded with ligand gated olfactory receptors. Mosquito sensory receptors consist of three main families comprising odorant receptors (Ors), ionotropic receptors (Irs), and gustatory receptors (Grs). Detection of semiochemicals via olfactory receptors modulates behaviors including …

Chemoreceptors From the Hawk Moth Manduca Sexta L
… I cloned and characterized four M. sexta chemoreceptors. Differential screening of a male antennal cDNA library before the publication of the Drosophila melanogaster genome yielded one G coupled-protein receptor that had no matches in Genbank databases and the results of RT-PCR and quantitative …

A NOVEL ROLE FOR CYTOCHROME P450 G 35 (CYP4G35) IN ODOR PROCESSING IN AEDES AEGYPTI MOSQUITOES
… structure. The sensilla hair houses many chemoreceptors, including odorant, ionotropic, and gustatory receptors. The volatile odorants enter the sensilla lymph through pores to bind to the receptors. Maintaining odor receptor sensitivity through degrading these odorants is essential for odor …

Tasting light through hydrogen peroxide : molecular mechanisms and neural circuits
… by the LITE-1 and GUR-3 proteins, both putative gustatory receptors, as well as by the conserved antioxidant enzyme peroxiredoxin PRDX-2. My results suggest that the LITE-1/GUR-3 family of receptors likely detects light through its generation of hydrogen peroxide or of another redox product. This …

Evolution of the Gr family of gustatory and odorant receptors in mosquitoes
… typically revolve around taste and smell. Of the receptors involved in chemoperception, the gustatory receptor (Gr) protein family comprises most of the diversity in the insect chemoreceptor superfamily, including within it not only taste receptors, but select olfactory receptors as well. Manual …

Cells that Kill: The Chemosensory Cell Types of Aedes aegypti Mosquitoes
… following the cloning of the first odorant receptors in1991 has shown that each mouse olfactory sensory neuron (OSN) expresses a single odorant receptor. Early work in Drosophila melanogaster flies reported a similar organization, although some key differences were noted. Insects detect …

Reproductive Genomics in the Stick Insect Clitarchus hookeri
… proteins (OBPs), chemosensory proteins, odorant receptors, ionotropic receptors and gustatory receptors. Among them, OBPs have three recently duplicated copies (OBP4, OBP5 and OBP6) that may underlie key adaptive events during sensory evolution. The annotation of digestive enzymes from both the …

A SINGLE GUSTATORY RECEPTOR CAN SWITCH THE INCENTIVE SALIENCE OF A SPECIFIC REWARD
… These results demonstrate how sensory receptors can dissociate reward perception that guides immediate and long-term behavior. This work also demonstrates how polymorphism of a single sensory receptor can allow evolution of long-term learned behavior utilizing the inherent plasticity of …

Molecular evolution of a superfamily of chemoreceptors in Musca domestica and Ceratitis capitata
… receptor subfamily in M. domestica and the gustatory receptor subfamily in C. capitata were annotated, and phylogenic analyses were performed. Compared with Drosophila melanogaster, the M. domestica odor receptor repertoire is considerably larger with 84 models in the gene set, plus OrCo (59 …
