mec-10(tm1552) is a recessive allele and acts in the touch neurons. Animals were touched with an eyelash at the indicated positions; escape responses (reversals) were scored as described. mec-10(tm1552)/+ heterozygous animals showed wild-type touch sensitivity at all positions. An extrachromosomal array carrying a pmec-4::mec-10(+) transgene rescued the phenotype of the mec-10(tm1552) homozygote at all positions; statistical significance (**P < 0.01 at position 3; ***P < 0.001 at positions 1 and 2) is according to the Student's t-test (n = 100 for each genotype over 5 different days).
