    A moth odorant receptor highly expressed in the ovipositor is involved in detecting host-plant volatiles

    Rui-Ting Li, Ling-Qiao Huang ... Chen-Zhu Wang
    A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.

    Single amino acid residue mediates reciprocal specificity in two mosquito odorant receptors

    Flavia P Franco, Pingxi Xu ... Walter S Leal
    The southern house mosquito senses the oviposition attractants skatole and indole with two receptor proteins sharing only 50% amino acid identity, and having the residues alanine-73 and leucine-74 in the skatole and indole receptors, respectively, control their specificity.

    Olfactory receptor neurons use gain control and complementary kinetics to encode intermittent odorant stimuli

    Srinivas Gorur-Shandilya, Mahmut Demir ... Thierry Emonet
    Olfactory receptor neurons adapt to odorant mean and variance and use complementary kinetics to preserve the timing of odorant encounters, despite adaptation slowing down transduction.

    Expanding the olfactory code by in silico decoding of odor-receptor chemical space

    Sean Michael Boyle, Shane McInally, Anandasankar Ray
    A computational method that can screen thousands of chemicals and predict which odorants will interact with specific odorant receptors in flies may ultimately aid the development of more effective insect repellents.

    Olfactory receptor accessory proteins play crucial roles in receptor function and gene choice

    Ruchira Sharma, Yoshiro Ishimaru ... Hiroaki Matsunami
    G protein-coupled odorant receptors regulate their own gene transcription based on their cell surface trafficking, which is facilitated by receptor transporting protein (RTP) family members.

    The origin of the odorant receptor gene family in insects

    Philipp Brand, Hugh M Robertson ... Brian R Johnson
    The insect odorant receptor gene family evolved at the base of the class Insecta before the evolution of flight and perhaps as an adaptation to terrestriality, and was therefore an important evolutionary novelty for insects.

    Adaptation of olfactory receptor abundances for efficient coding

    Tiberiu Teşileanu, Simona Cocco ... Vijay Balasubramanian
    A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.

    Antagonism in olfactory receptor neurons and its implications for the perception of odor mixtures

    Gautam Reddy, Joseph D Zak ... Venkatesh N Murthy
    Computational and theoretical analyses offer novel and unexpected insight into how complex, naturally occurring odor mixtures are parsed and normalized at the very first stage of olfaction.

    A novel lineage of candidate pheromone receptors for sex communication in moths

    Lucie Bastin-Héline, Arthur de Fouchier ... Nicolas Montagné
    In moths, male receptors tuned to type I female pheromones may not have a monophyletic origin.

    Robust olfactory responses in the absence of odorant binding proteins

    Shuke Xiao, Jennifer S Sun, John R Carlson
    Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.
