Upon presentation of two distinct chemoattractants such as sodium acetate and diacetyl simultaneously, the nematode <I>Caenorhabditis elegans</I> 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 <I>chep-1(qr1)</I> (CHEmosensory Preference) mutant preferred sodium acetate to diacetyl, while the <I>chep-2(qr2)</I> mutant preferred diacetyl to sodium acetate in simultaneous presentation of these chemoattractants. The chemotaxis behavior of <I>chep-2(qr2)</I> mutant in simultaneous presentation suggests a function of <I>chep-2</I> gene products within the chemosensory informational integration pathway as well as in the chemosensory pathway.
