求偶行为是动物行为研究中的范例。在果蝇中,求偶行为由fruitless(fru)的基因所控制。果蝇的fru基因在雌雄中存在不同的剪接方式,雄的剪接方式是雄果蝇求偶行为和性别决定所必需的。本文就此基因的结构、功能和调控作一阐述。
Courtship behavior is a model in the study of animal behavior. In Drosophila, this behavior is controlled by the fruitless (fru) gene. The way of the fru gene splicing in females is different from that in males, which is essential in males' courtship and sex determination. This paper reviews and summarizes the progress in the research of the structure, functions and regulation of fru gene.
