Serotonergic neuronal death and concomitant serotonin deficiency curb copulation ability of Drosophila platonic mutants

Abstract

Drosophila platonic (plt) mutant males court with females but fail to copulate. Here, the authors find plt is an allele of scribblerand may disrupt courtship behaviour via developmental disruption of a subgroup of serotonergic Doublesex+ neurons in the abdominal ganglion.
