棉花属，鹅及其... -Agritrop
抽象的棉花，棉花属，包括〜50种分布在欧洲以外所有大陆的热带和亚热带地区的物种。在这里，我们提供了一个关于美国同种多倍体物种的山地植物和驯化的进化史的概要，从而整合了基本分类学研究，生物地理，分子遗传学，系统发育分析和考古学的数据。These diverse sources of information provide a temporal and phylogenetic perspective on diversification among the diploids and on polyploid formation, uncover multiple previously cryptic interspecific hybridizations, clarify and contribute to the taxonomy of the genus, and offer a firm foundation for understanding parallel domestications in Mesoamerica and South America, which led to the globally important cotton crop species G. barbadense and G. hirsutum .Gossypium因此提供了一个证明典型的例子，说明了基本植物发现的重要性和实用性，并结合了现代技术能力，以产生对进化史的基因组见解。We also review the current state of our knowledge regarding the archaeological history of cotton domestication and diffusion in the Americas, a seemingly unlikely story entailing parallel domestication origins and parallel directional selection tracing to 8,000 ( G. barbadense ) and 5,500 ( G. hirsutum ) years ago, transforming two geographically isolated wild short-day perennial shrubs having small capsules and seeds covered by short,棕褐色的表皮毛状体进入现代日间长度中的年度，具有丰富，细的白色纤维。几千年后，这种双重驯化是无意的且最近有意间的，随着两种物种在不同半球的初始驯化后接触，这是无意的，最近有意的。因此，重申了物种差异和生物团聚的循环，这次是在多倍体水平上。了解这种进化史对于我们对世界上最重要的纤维植物基因组建筑的理解至关重要，并为我们对一般生物学原理的理解做出了重大贡献。关键词：系统发育学；多倍体，杂交，驯化；考古学;山毛毛； Gossypium barbadense
