Profiling of olfactory receptor gene expression in whole human olfactory mucosa. [PDF]
PLoS ONE, 2014 Olfactory perception is mediated by a large array of olfactory receptor genes. The human genome contains 851 olfactory receptor gene loci. More than 50% of the loci are annotated as nonfunctional due to frame-disrupting mutations.

Identification and Expression Analyses of Olfactory Gene Families in the Rice Grasshopper, Oxya chinensis, From Antennal Transcriptomes [PDF]
Frontiers in Physiology, 2019 The rice grasshopper Oxya chinensis is an important agricultural pest of rice and other gramineous plants. Chemosensory genes are crucial factors in direct interactions with odorants in the olfactory process.

A screen for genes expressed in the olfactory organs of Drosophila melanogaster identifies genes involved in olfactory behaviour. [PDF]
PLoS ONE, 2012 BACKGROUND: For insects the sense of smell and associated olfactory-driven behaviours are essential for survival. Insects detect odorants with families of olfactory receptor proteins that are very different to those of mammals, and there are likely to be

Chemoreceptor co-expression in Drosophila melanogaster olfactory neurons
eLife, 2022 Drosophila melanogaster olfactory neurons have long been thought to express only one chemosensory receptor gene family. There are two main olfactory receptor gene families in Drosophila, the odorant receptors (ORs) and the ionotropic receptors (IRs). The

The complete swine olfactory subgenome: expansion of the olfactory gene repertoire in the pig genome [PDF]
BMC Genomics, 2012 Insects and animals can recognize surrounding environments by detecting thousands of chemical odorants. Olfaction is a complicated process that begins in the olfactory epithelium with the specific binding of volatile odorant molecules to dedicated ...

Single-Cell RNA-Seq Analysis of Olfactory Mucosal Cells of Alzheimer’s Disease Patients
Cells, 2022 Olfaction is orchestrated by olfactory mucosal cells located in the upper nasal cavity. Olfactory dysfunction manifests early in several neurodegenerative disorders including Alzheimer’s disease, however, disease-related alterations to the olfactory ...

Unravelling the Olfactory Sense: From the Gene to Odor Perception. [PDF]
Chemical Senses, 2015 Although neglected by science for a long time, the olfactory sense is now the focus of a panoply of studies that bring new insights and raises interesting questions regarding its functioning. The importance in the clarification of this process is of interest for science, but also motivated by the food and perfume industries boosted by a consumer ...

Comparative Analysis Reveals the Adaptive Evolution of Olfactory System in the Swamp Eel (Monopterus albus) Based on the Chromosome‐Level Genome [PDF]
Ecology and EvolutionThe swamp eel (Monopterus albus), known for its benthic and nocturnal feeding habits, exhibits a keen sense of smell. To date, the genomic basis for its adaptive evolution of olfactory system was poorly investigated.
