Frontiers in Physiology, 2018 The key to the coexistence of two or more species on the same host is ecological niche separation. Adult Eucryptorrhynchus scrobiculatus and E. brandti both feed on the tree of heaven, Ailanthus altissima, but on different sections of the plant ...

Solution Structure of a Chemosensory Protein from the Desert Locust Schistocerca gregaria,
Biochemistry, 2006 Chemical stimuli, generally constituted by small volatile organic molecules, are extremely important for the survival of different insect species. In the course of evolution, insects have developed very sophisticated biochemical systems for the binding and the delivery of specific semiochemicals to their cognate membrane-bound receptors.

Frontiers in Physiology, 2018 The chemosensory gene families of insects encode proteins that are crucial for host location, mate finding, oviposition, and avoidance behaviors. The insect peripheral chemosensory system comprises odorant receptors (ORs), gustatory receptors (GRs ...

BMC Genomics, 2019 Background Olfaction and gustation underlie behaviors that are crucial for insect fitness, such as host and mate selection. The detection of semiochemicals is mediated via proteins from large and rapidly evolving chemosensory gene families; however, the ...

The Amphioxus SoxB Family: Implications for the Evolution of Vertebrate Placodes [PDF]
, 2007 Cranial placodes are regions of thickened ectoderm that give rise to sense organs and ganglia in the vertebrate head. Homologous structures are proposed to exist in urochordates, but have not been found in cephalochordates, suggesting the first chordates

Identification of chemosensory receptor genes in Manduca sexta and knockdown by RNA interference
BMC Genomics, 2012 Background Insects detect environmental chemicals via a large and rapidly evolving family of chemosensory receptor proteins. Although our understanding of the molecular genetic basis for Drosophila chemoreception has increased enormously in the last ...

Interaction of GTP-binding regulatory proteins with chemosensory receptors.
Journal of Biological Chemistry, 1987 GTP-binding regulatory proteins (G-proteins) were identified in chemosensory membranes from the channel catfish, Ictalurus punctatus. The common G-protein beta-subunit was identified by immunoblotting in both isolated olfactory cilia and purified taste plasma membranes.

Non-synaptic inhibition between grouped neurons in an olfactory circuit. [PDF]
, 2012 Diverse sensory organs, including mammalian taste buds and insect chemosensory sensilla, show a marked compartmentalization of receptor cells; however, the functional impact of this organization remains unclear.

A divergent CheW confers plasticity to nucleoid-associated chemosensory arrays.
PLoS Genetics, 2019 Chemosensory systems are highly organized signaling pathways that allow bacteria to adapt to environmental changes. The Frz chemosensory system from M. xanthus possesses two CheW-like proteins, FrzA (the core CheW) and FrzB.
