Abstract
The behavioral responses by the nematode Caenorhabditis elegans to 12 organic compounds was explored using tethered nematode and computer tr acking methods. Results indicate that the nematode is attracted to ace tone, diethyl ether, isoamyl acetate, isoamyl alcohol, 2,4-pentanedion e, and n-propanol. No responses were detected to acetaldehyde, acetylc holine, ethanol, formaldehyde, i-propanol, and valerate. Isoamyl aceta te and acetone were found to be the most potent attractants eliciting minimal responses at concentrations near 10(-10) M. The geometry and c harge distribution of a single hypothetical receptor that would intera ct with all the compounds that elicited a response and none of the com pounds that failed to elicit a response is explored.
