绝大多数真核生物是有性繁殖的,但性系统的性质和性别决定的机制往往差异很大,即使在关系密切的物种之间也是如此。一些动植物物种在一生中会改变性别,有些物种是两性的,有些是雌雄同体的,有些是通过高度分化的染色体来决定性别的,而另一些则是根据环境来决定性别的。测试关于这种多样性的原因和后果的进化假说需要放在系统发育背景下的种间数据。由于缺乏可获得的数据,列出了整个真核生命树的性系统和性别决定机制,这种比较研究受到了阻碍。在这里,我们描述了一个为便于获取性系统和性染色体信息而开发的数据库,其中包括11,038种植物、705种鱼、173种两栖动物、593种非鸟类爬行动物、195种鸟类、479种哺乳动物和11,556种无脊椎动物的性系统数据。
The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual system and the mechanism of sex determination often vary remarkably, even among closely related species. Some species of animals and plants change sex across their lifespan, some contain hermaphrodites as well as males and females, some determine sex with highly differentiated chromosomes, while others determine sex according to their environment. Testing evolutionary hypotheses regarding the causes and consequences of this diversity requires interspecific data placed in a phylogenetic context. Such comparative studies have been hampered by the lack of accessible data listing sexual systems and sex determination mechanisms across the eukaryotic tree of life. Here, we describe a database developed to facilitate access to sexual system and sex chromosome information, with data on sexual systems from 11,038 plant, 705 fish, 173 amphibian, 593 non-avian reptilian, 195 avian, 479 mammalian, and 11,556 invertebrate species.
