在体内受精的动物中，雄性在交配过程中转移配子和精液，这两者都是成功繁殖所必需的。在果蝇和其他昆虫中，精液产生于成对的附属腺（AG）、射精管和射精球。地方melanogaster AG已经成为雄性生殖生物学这一组成部分的重要模型系统。果蝇AG产生的精液蛋白是雌性正确储存和使用精子所必需的，也是建立和维持一套促进生殖成功的短期和长期交配后雌性生理反应的关键。果蝇AG由两种主要细胞类型组成。大多数AG细胞被称为主细胞，负责产生许多精液蛋白。少数细胞，约4%，被称为次级细胞。这些细胞局限于D. melanogaster AG在维持雌性长期交配后反应中可能起着特别重要的作用。许多关于果蝇AG进化的研究表明，腺中产生的蛋白质进化得很快，转录组也是如此。在这里，我们调查的次级细胞的数量和位置的AG在收集的8个物种跨越整个历史的果蝇属的演变。我们记录了一个迄今为止未被充分认识的快速进化速度为这些专门的AG细胞的数量和位置，提出了几个问题，这种变化的发展，功能和进化意义。
In animals with internal fertilization, males transfer gametes and seminal fluid during copulation, both of which are required for successful reproduction. In Drosophila and other insects, seminal fluid is produced in the paired accessory gland (AG), the ejaculatory duct, and the ejaculatory bulb. The D. melanogaster AG has emerged as an important model system for this component of male reproductive biology. Seminal fluid proteins produced in the Drosophila AG are required for proper storage and use of sperm by the females, and are also critical for establishing and maintaining a suite of short- and long-term postcopulatory female physiological responses that promote reproductive success. The Drosophila AG is composed of two main cell types. The majority of AG cells, which are referred to as main cells, are responsible for production of many seminal fluid proteins. A minority of cells, about 4%, are referred to as secondary cells. These cells, which are restricted to the distal tip of the D. melanogaster AG, may play an especially important role in the maintenance of the long-term female post-mating response. Many studies of Drosophila AG evolution have suggested that the proteins produced in the gland evolve quickly, as does the transcriptome. Here, we investigate the evolution of secondary cell number and position in the AG in a collection of eight species spanning the entire history of the Drosophila genus. We document a heretofore underappreciated rapid evolutionary rate for both number and position of these specialized AG cells, raising several questions about the developmental, functional, and evolutionary significance of this variation.
