tap, a Drosophila bHLH gene expressed in chemosensory organs

Gene, 1997
We have isolated a Drosophila bHLH gene, tap, that is expressed in a small subset of neurons when they undergo differentiation. In the peripheral nervous system, tap is expressed exclusively in one of the neurons that innervate each larval chemosensory organ, possibly controlling the specific properties of that neuron. Sequence comparisons suggest that

Comparative transcriptome analysis of chemosensory genes in two sister leaf beetles provides insights into chemosensory speciation

Insect Biochemistry and Molecular Biology, 2016
Divergence in chemosensory traits has been posited as an important component of chemosensory speciation in insects. In particular, chemosensory genes expressed in the peripheral sensory neurons are likely to influence insect behaviors such as preference for food, oviposition sites, and mates.

Identification of Chemosensory Receptor Genes from Vertebrate Genomes

2013
Chemical senses are essential for the survival of animals. In vertebrates, mainly three different types of receptors, olfactory receptors (ORs), vomeronasal receptors type 1 (V1Rs), and vomeronasal receptors type 2 (V2Rs), are responsible for the detection of chemicals in the environment.

A gene affecting the specificity of the chemosensory neurons of Drosophila

Nature, 1987
The sensilla on the proboscis and tarsi of Drosophila contain five neurons, four chemosensory and one mechanosensory. The sugar-sensitive neuron, designated S, carries independent acceptor sites for pyranose, furanose and trehalose. Two others, L1 and L2, respond to salts.

Expressed sequence tags (EST) identify genes preferentially expressed in catfish chemosensory tissues

Molecular Brain Research, 1994
Expressed sequence tags (ESTs) for the catfish (Ictalurus punctatus) were identified and characterized by shotgun sequencing coupled to Northern analysis. We have identified and characterized a number of cDNA clones from a catfish olfactory mucosal library that show differential tissue expression including several that are enriched in chemosensory ...

Connectivity of chemosensory neurons is controlled by the gene poxn in Drosophila

Nature, 1992
The function of the nervous system depends on the formation of a net of appropriate connections, but little is known of the genetic program underlying this process. In Drosophila two genes that specify different types of sense organs have been identified: cut (ct), which specifies the formation of external sense organs as opposed to chordotonal organs,

Insect chemosensory receptor genes: expression, expansion and functional evolution

Insects depend on chemosensation - olfaction and gustation - for foraging, mating, defense against parasites etc. These vital activities are mediated primarily by three chemosensory receptor gene families: odorant receptors (ORs), ionotropic receptors (IRs), and gustatory receptors (GRs).

Evolution of Chemosensory Receptor Genes in Primates and Other Mammals

2011
Chemosensory receptors for detecting chemical molecules in the environment are present in essentially all motile organisms ranging from bacteria to mammals. Mammals have at least seven different gene families of chemosensory receptors: olfactory receptors (ORs), vomeronasal (pheromone) receptors type 1 and 2, trace amine-associated receptors, formyl ...
