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.

An epigenetic repressor TRIM66 dictates monogenic olfactory receptor expression, neural activity, and olfactory behavior [PDF]
Nature CommunicationsOlfactory receptor gene choice is an intricate example of monogenic and monoallelic expression, where one out of over 1000 receptor genes is transcribed in each olfactory sensory neuron.

Transcriptome Analysis Reveals Olfactory System Expression Characteristics of Aquatic Snakes
Frontiers in Genetics, 2022 Animal olfactory systems evolved with changes in habitat to detect odor cues from the environment. The aquatic environment, as a unique habitat, poses a formidable challenge for olfactory perception in animals, since the higher density and viscosity of ...

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.

Coevolution of the olfactory organ and its receptor repertoire in ray-finned fishes
BMC Biology, 2022 Background Ray-finned fishes (Actinopterygii) perceive their environment through a range of sensory modalities, including olfaction. Anatomical diversity of the olfactory organ suggests that olfaction is differentially important among species. To explore

Olfactory function in the trace amine-associated receptor family (TAARs) evolved twice independently
Scientific Reports, 2021 Olfactory receptor families have arisen independently several times during evolution. The origin of taar genes, one of the four major vertebrate olfactory receptor families, is disputed.

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

Olfactory expression of trace amine-associated receptors requires cooperative cis-acting enhancers
Nature Communications, 2021 How olfactory sensory neurons express one allele of one TAAR gene is not well understood. Here the authors identify two cooperative cis-acting enhancers that govern TAAR gene choice and that share both similarities and differences with known olfactory ...

Identification of male- and female-specific olfaction genes in antennae of the oriental fruit fly (Bactrocera dorsalis) [PDF]
, 2016 The oriental fruit fly (Bactrocera dorsalis) is a species of tephritid fruit fly, endemic to Southeast Asia but also introduced to many regions of the US, and it is one of the major pest species with a broad host range of cultivated and wild fruits ...

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
