Time to reach the edge of the food lawn during multisensory integration.

Wild type, mutants and transgenic animals are examined for the time taken to reach the edge of the food lawn away from the repellent. The average time taken for 90% of the worms in one assay to reach the edge of a E. coli OP50 food lawn during exposure to 100% 2-nonanone is presented for each genotype (Experimental Procedures and S1 Fig). n = 2–4 assays for each genotype, 20–25 animals tested in each assay, mutants or transgenic animals are compared with wild-type animals or non-transgenic siblings tested on the same days with student’s t test, Mean ± SEM.
