Upon presentation of two distinct chemoattractants such as sodium acetate and diacetyl simultaneously, the nematode Caenorhabditis elegans was preferentially attracted by one of these chemoattractants. We isolated two mutants having altered preference of chemotaxis behavior toward simultaneous presentation of sodium acetate and diacetyl. The chep-1(qr1) (CHEmosensory Preference) mutant preferred sodium acetate to diacetyl, while the chep-2(qr2) mutant preferred diacetyl to sodium acetate in simultaneous presentation of these chemoattractants. The chemotaxis behavior of chep-2(qr2) mutant in simultaneous presentation suggests a function of chep-2 gene products within the chemosensory informational integration pathway as well as in the chemosensory pathway.
