EGL-4 promotes turning behavior of C. elegans males during mating

During mating, C. elegans males whose tails have reached the head or tail of their intended mates are able to switch to scanning the other side by performing a turn during which the male’s tail curls ventrally all the while keeping in contact with the hermaphrodite. The ability to execute turns efficiently is dependent upon serotonergic neurons in the posterior ventral nerve cord that stimulate diagonal muscles by activating a serotonin receptor, SER-1. Here we show that turning behavior is abnormal in males lacking a cGMP-dependent protein kinase, EGL-4. egl-4 mutant males are also resistant to ventral tail curling induced by exogenous serotonin.
