The whole body transcriptome of Coleophora obducta reveals important olfactory proteins [PDF]
PeerJ, 2020 Background The tiny casebearer moth Coleophora obducta, an important defoliator of Larix spp., is a major threat to ecological security in north China. Studies have shown that C. obducta is strongly specific to host plants; it is unable complete its life

Involvement of the olfactory system in the induction of anti-fatigue effects by odorants. [PDF]
PLoS ONE, 2018 Some components of the neural circuits underlying innate odor-evoked responses have recently been elucidated. Odor information detected by the olfactory receptors is transmitted from the olfactory bulb to the cortical amygdala, where physiological and ...

Predicting Human Olfactory Perception from Activities of Odorant Receptors. [PDF]
iScience, 2020 Summary Odor perception in humans is initiated by activation of odorant receptors (ORs) in the nose. However, the ORs linked to specific olfactory percepts are unknown, unlike in vision or taste where receptors are linked to perception of different ...

The structural basis of odorant recognition in insect olfactory receptors
Nature, 2021 Olfactory systems must detect and discriminate amongst an enormous variety of odorants1. To contend with this challenge, diverse species have converged on a common strategy in which odorant identity is encoded through the combinatorial activation of ...

PLoS ONE, 2022 Olfaction, one of the most important sensory systems governing insect behavior, is a possible target for pest management. Therefore, in this study, we analyzed the antennal transcriptome of the cowpea beetle, Callosobruchus maculatus (F.) (Coleoptera ...

The diversity and evolution of odorant receptors in beetles (Coleoptera)
Insect molecular biology (Print), 2020 The insect odorant receptors (ORs) are amongst the largest gene families in insect genomes and the primary means by which insects recognize volatile compounds. The evolution of ORs is thus instrumental in explaining the chemical ecology of insects and as

Onset of Odorant Receptors [PDF]
Annals of the New York Academy of Sciences, 2009 Odorant receptors are thought to be critical determinants of olfactory sensory neuron axon targeting and organization. Nonetheless, a systematic characterization of the onset of odorant receptor expression has not yet been done in the main olfactory epithelium.

Odorant Receptor Inhibition Is Fundamental to Odor Encoding [PDF]
Current Biology, 2019 SUMMARYMost natural odors are complex mixtures of many volatile components, competing to bind odorant receptors (ORs) expressed in olfactory sensory neurons (OSNs) of the nose. To date surprisingly little is known about how OR antagonism shapes neuronal representations in the periphery of the olfactory system.

Evolution, developmental expression and function of odorant receptors in insects
Journal of Experimental Biology, 2020 Animals rely on their chemosensory system to discriminate among a very large number of attractive or repulsive chemical cues in the environment, which is essential to respond with proper action.

Advantage of the Highly Restricted Odorant Receptor Expression Pattern in Chemosensory Neurons of Drosophila. [PDF]
PLoS ONE, 2013 A fundamental molecular feature of olfactory systems is that individual neurons express only one receptor from a large odorant receptor gene family. While numerous theories have been proposed, the functional significance and evolutionary advantage of ...
