Complex evolutionary dynamics of massively expanded chemosensory receptor families in an extreme generalist chelicerate herbivore [PDF]

open access: yes, 2016
While mechanisms to detoxify plant produced, anti-herbivore compounds have been associated with plant host use by herbivores, less is known about the role of chemosensory perception in their life histories.

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

Odor Identification Quantitatively by Odorant Receptor Vectors

open access: yes, 2022
Abstract Background: Odors are perceived by individuals through sensation, memory, experience, etc., and mainly subjective and qualitative evaluation has been performed until now. On the other hand, since Buck et al. succeeded in cloning the odorant receptor in 1991, researchers have shown interest in olfaction system, and molecular biology ...

Asymmetric ephaptic inhibition between compartmentalized olfactory receptor neurons. [PDF]

open access: yes, 2019
In the Drosophila antenna, different subtypes of olfactory receptor neurons (ORNs) housed in the same sensory hair (sensillum) can inhibit each other non-synaptically.

Insights on the nutritional ecology of a nocturnal pollinating insect

open access: yesInsect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.

Engineered odorant receptors illuminate structural principles of odor discrimination

open access: yes, 2023
AbstractA central challenge in olfaction is understanding how the olfactory system detects and distinguishes odorants with diverse physicochemical properties and molecular configurations. Vertebrate animals perceive odors via G protein-coupled odorant receptors (ORs). In humans, ∼400 ORs enable the sense of smell. The OR family is composed of two major

Non-synaptic inhibition between grouped neurons in an olfactory circuit. [PDF]

open access: yes, 2012
Diverse sensory organs, including mammalian taste buds and insect chemosensory sensilla, show a marked compartmentalization of receptor cells; however, the functional impact of this organization remains unclear.

Reverse chemical ecology approach for the identification of an oviposition attractant for Culex quinquefasciatus. [PDF]

open access: yes, 2018
Pheromones and other semiochemicals play a crucial role in today's integrated pest and vector management strategies. These semiochemicals are typically discovered by bioassay-guided approaches.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Molecular recognition of an odorant by the murine trace amine-associated receptor TAAR7f

open access: yesNature Communications
There are two main families of G protein-coupled receptors that detect odours in humans, the odorant receptors (ORs) and the trace amine-associated receptors (TAARs).
