果蝇柏拉图式(plt)雄性追求雌性,但不能交配。在这里,我们表明,plt是一个等位基因的scribbler(sbb),BMP信号成分。在幼虫中sbb敲低导致大约8个多巴胺能神经元的损失,这些神经元表达性别决定蛋白Doublemex(Dsx)。从dsx表达神经元中遗传剥夺5-羟色胺(5-HT)导致交配缺陷。因此,sbb+是发育所需的dsx表达神经元的一个特定的子集,支持正常执行交配在成人提供5-HT的生存。我们的研究强调了保守的参与,BMP能神经元的控制交配机制和关键作用的BMP信号在性别特异性电路的形成。 果蝇柏拉图式(plt)突变雄性追求雌性但不能交配。在这里,作者发现plt是scribbler的一个等位基因,可能通过腹神经节中一个亚组的多巴胺能Doublex+神经元的发育破坏来破坏求偶行为。
Drosophila platonic (plt) males court females, but fail to copulate. Here we show that plt is an allele of scribbler (sbb), a BMP signalling component. sbb knockdown in larvae leads to the loss of approximately eight serotonergic neurons, which express the sex-determinant protein Doublesex (Dsx). Genetic deprivation of serotonin (5-HT) from dsx-expressing neurons results in copulation defects. Thus, sbb+ is developmentally required for the survival of a specific subset of dsx-expressing neurons, which support the normal execution of copulation in adults by providing 5-HT. Our study highlights the conserved involvement of serotonergic neurons in the control of copulatory mechanisms and the key role of BMP signalling in the formation of a sex-specific circuitry. Drosophila platonic (plt) mutant males court with females but fail to copulate. Here, the authors find plt is an allele of scribbler and may disrupt courtship behaviour via developmental disruption of a subgroup of serotonergic Doublesex+ neurons in the abdominal ganglion.
