Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, EarlyView.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

An Explicit Electron-Vibron Model for Olfactory Inelastic Electron Transfer Spectroscopy

, 2019
The vibrational theory of olfaction was posited to explain subtle effects in the sense of smell inexplicable by models in which molecular structure alone determines an odorant's smell.

Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ

Journal of Anatomy, EarlyView.
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

Genomic content of chemosensory genes correlates with host range in wood-boring beetles (Dendroctonus ponderosae, Agrilus planipennis, and Anoplophora glabripennis)

BMC Genomics, 2019
Background Olfaction and gustation underlie behaviors that are crucial for insect fitness, such as host and mate selection. The detection of semiochemicals is mediated via proteins from large and rapidly evolving chemosensory gene families; however, the ...

Conflicting adaptations in an inhibitory feedback circuit

The Journal of Physiology, EarlyView.
Abstract figure legend We studied activity‐dependent adaptation in the fruit fly Drosophila’s memory centre, the mushroom body. Here, excitatory Kenyon cells (KCs) receive feedback inhibition from the anterior paired lateral (APL) neuron. When KCs are artificially overactivated for 24 h, both KCs and APL reduce their sensitivity to excitation (‘↓ Exc’,

Beyond Modeling: All-Atom Olfactory Receptor Model Simulations

Frontiers in Genetics, 2012
Olfactory receptors (ORs) are a type of GTP-binding protein-coupled receptor (GPCR). These receptors are responsible for mediating the sense of smell through their interaction with odor ligands. OR-odorant interactions marks the first step in the process

Disparity of turbinal bones in placental mammals

The Anatomical Record, Volume 309, Issue 4, Page 749-777, April 2026.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Adaptation of olfactory receptor abundances for efficient coding

, 2019
Olfactory receptor usage is highly heterogeneous, with some receptor types being orders of magnitude more abundant than others. We propose an explanation for this striking fact: the receptor distribution is tuned to maximally represent information about ...

Functional Expression of Mammalian Odorant Receptors [PDF]

Chemical Senses, 2005
The olfactory sensory neurons (OSNs) in the olfactory epithelium of the nose detect and discriminate a large number of volatile environmental chemicals. This ability is essential for animals to find prey, food, mates, predators and toxic compounds. In OSNs, odorant receptor (OR) proteins, members of the G-protein coupled receptor (GPCR) superfamily ...

Effect of Heat Treatment on the Flavor Characteristics of Vacuum Freeze‐Dried Pacific White Shrimp (Litopenaeus vannamei)

eFood, Volume 7, Issue 2, April 2026.
A post‐freeze‐drying heat treatment at 150°C optimizes shrimp flavor by boosting umami compounds and generating roasted aromas via the Maillard reaction. This strategy successfully bridges the texture‐flavor trade‐off, enabling premium ready‐to‐eat shrimp products.
