WebSep 22, 2015 · In C. elegans, two pairs of ciliated chemosensory neurons called AWA and AWC mediate attraction to volatile odors. Chemotaxis to low concentrations of diacetyl requires the AWA sensory neurons and ODR-10, a G-protein-coupled olfactory receptor (Bargmann et al., 1993, Sengupta et al., 1996).Other GPCRs in AWA and AWC are … WebC. elegans chemotaxis assay setup with odorants diacetyl and benzaldehyde and control EtOH.
http://www.wormbook.org/chapters/www_chemosensation/chemosensation.html WebC. elegans senses chemicals in its environment using a collection of sensory neurons, the amphid neurons, whose cell bodies are located near the nerve ring in the head of the animal. Amphid neurons extend unbranched, ciliated sensory dendrites anteriorly to the tip of the animal’s nose.
