Transcriptome Surveys in Silverfish Suggest a Multistep Origin of the Insect Odorant Receptor Gene Family

Frontiers in Ecology and Evolution, 2019
The insect odorant receptor (Or) gene family is among the largest multigene families in insect genomes, but its evolutionary origin and mode of expansion is still a matter of debate. We performed transcriptomic surveys of two wingless insect species, the

Chemosensation in C. elegans [PDF]

WormBook, 2006
C. elegans has a highly developed chemosensory system that enables it to detect a wide variety of volatile (olfactory) and water-soluble (gustatory) cues associated with food, danger, or other animals. Much of its nervous system and more than 5% of its genes are devoted to the recognition of environmental chemicals.

One nose, one brain: contribution of the main and accessory olfactory system to chemosensation

Frontiers in Neuroanatomy, 2012
The accessory olfactory system is present in most tetrapods. It is involved in the perception of chemical stimuli, being implicated also in the detection of pheromone.

Chemosensation and genetic individuality [PDF]

Reproduction, 2001
Numerous studies have shown that there are measurable behavioural consequences that can result from the olfactory recognition of alleles borne at the major histocompatibility complex (MHC). These consequences include simple individual recognition, disassortative mate preference, discrimination of kin from non-kin and whether a pregnancy is carried to ...

Luminal chemosensing in the gastroduodenal mucosa [PDF]

Current Opinion in Gastroenterology, 2017
We report recently published knowledge regarding gut chemosensory mechanisms focusing on nutrient-sensing G protein-coupled receptors (GPCRs) expressed on gut enteroendocrine cells (EECs), tuft cells, and in afferent nerves in the gastroduodenal mucosa and submucosa.Gene profiling of EECs and tuft cells have revealed expression of a variety of nutrient-

Vomeronasal and Olfactory Structures in Bats Revealed by DiceCT Clarify Genetic Evidence of Function

Frontiers in Neuroanatomy, 2018
The degree to which molecular and morphological loss of function occurs synchronously during the vestigialization of traits is not well understood. The mammalian vomeronasal system, a sense critical for mediating many social and reproductive behaviors ...

Mechanosensitivity of Murine Lung Slowly Adapting Receptors: Minimal Impact of Chemosensory, Serotonergic, and Purinergic Signaling

Frontiers in Physiology, 2022
Murine slowly adapting receptors (SARs) within airway smooth muscle provide volume-related feedback; however, their mechanosensitivity and morphology are incompletely characterized.

Bacterial Chemosensing: Cooperative Molecular Logic

Current Biology, 2004
Bacterial chemotaxis is mediated by transmembrane receptors that bind attractant and repellent chemicals and control an intracellular protein kinase. Each cell contains thousands of receptor subunits that form a tightly packed array at one pole. Recent studies of bacterial behavior have begun to reveal the molecular logic of this sensory architecture.

Bitter taste receptors of the zebra finch (Taeniopygia guttata)

Frontiers in Physiology, 2023
Despite the important role of bitter taste for the rejection of potentially harmful food sources, birds have long been suspected to exhibit inferior bitter tasting abilities.
