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.

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,

Gene expression profiles of chemosensory genes of termite soldier and worker antennae

Insect Molecular Biology, 2022
ABSTRACTTermite caste differentiation and social behavior are appropriately regulated by the chemical signals among individuals in each colony. Signal transduction is well known to be triggered by the reception of odorant molecules by some binding proteins in the antennae, after which, a signal is transmitted to chemosensory receptors.

Transcriptomic analyses of chemosensory genes in Trichogramma japonicum (Hymenoptera: Trichogrammatidae)

Comparative Biochemistry and Physiology Part D: Genomics and Proteomics, 2021
Insects perceive dangerous or attractive chemicals in the environment (such as the presence of predators, food or mates) through their olfaction and gustation. This leads to host searching, mate finding and other behaviors that are critical for insect survival.

Selective Pressures on Drosophila Chemosensory Receptor Genes

Journal of Molecular Evolution, 2007
The evolution and patterns of selection of genes encoding 10 Drosophila odorant receptors (Or) and the sex pheromone receptor Gr68a were investigated by comparing orthologous sequences across five to eight ecologically diverse species of Drosophila. Using maximum likelihood estimates of dN/dS ratios we show that all 11 genes sampled are under purifying

Chemosensory genes in the head of Spodoptera litura larvae

Bulletin of Entomological Research, 2021
AbstractThe tobacco cutworm Spodoptera litura (Lepidoptera: Noctuidae) is a polyphagous pest with a highly selective and sensitive chemosensory system involved in complex physiological behaviors such as searching for food sources, feeding, courtship, and oviposition.

A reference gene set for chemosensory receptor genes of Manduca sexta

Insect Biochemistry and Molecular Biology, 2015
The order of Lepidoptera has historically been crucial for chemosensory research, with many important advances coming from the analysis of species like Bombyx mori or the tobacco hornworm, Manduca sexta. Specifically M. sexta has long been a major model species in the field, especially regarding the importance of olfaction in an ecological context ...

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

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.
