The molecular mechanism of speciation by sensory drive and its generality

本研究旨在揭示感官驱动物种形成的分子机制及其共性。在这项研究中，我们证明了可能与繁殖色彩形成有关的形态基因是在有性选择作用下进化出来的。我们还展示了视觉基因的多样性，这些基因可能通过性别选择形成了Nothobranchius物种繁殖色彩的多样性。根据这些结果，我们证明了包括性选择在内的感官驱动物种形成的整个机制是在负责繁殖颜色形成的基因上进行的，并通过对其他鱼类物种的分析证明了这种物种形成机制的普遍性。

The aim of this study was to reveal the molecular mechanism of speciation by sensory drive and its generality. In this study, we showed that the morphological genes those may be responsible for the formation of breeding coloration have evolved under sexual selection in cichlids. We also showed the diversity of visual genes that may form the diversity of breeding coloration by sexual selection in Nothobranchius species. According to these results, we demonstrated that the whole mechanism of speciation by sensory drive including sexual selection on the genes responsible for the formation of breeding coloration, and that the generality of this mechanism of speciation by analyzing other fish species.
