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. Web摘要： Olfactory signaling is initiated by interactions between odorants and olfactory receptors. We show that the C. elegans odr-10 gene is likely to encode a receptor for the odorant diacetyl. odr-10 mutants have a specific defect in chemotaxis to diacetyl, one of several odorants detected by the AWA olfactory neurons. odr-10 encodes a predicted …
