Abstract

Phenotypic analysis of the daf-11 and daf-21 mutants of Caenorhabditis elegans suggests that they have defects in components shared by processes analogous to vertebrate taste and olfaction. daf-11 and daf-21 mutations were previously shown to cause inappropriate response to the dauer-inducing pheromone. By mutational analysis and by disabling specific chemosensory sensilla with a laser, we show that neurons in the amphid sensilla are required for this pheromone response. Using behavioral assays, we find that daf-11 and daf-21 mutants are not defective ...
