项目摘要
The flowering plant genus Boechera, with 110 North American species and a number of endangered taxa, is frequently the focus of studies in plant ecology and evolutionary biology. Such studies seek to understand processes of divergent evolution and hybridization in a group that exhibits both sexual and asexual modes of reproduction. Unfortunately, conclusions drawn from previous studies on this group have been severely constrained by a poor understanding of the phylogenetic relationships among its members. Bailey et al. will combine studies from fieldwork across North America, DNA sequences, morphological assessments, and chromosomal information to clarify the phylogenetic relationships among species of Boechera, establish the number and distribution of divergent sexual species vs. asexual species, and assess species boundaries. The resulting phylogenetic tree will be used to test hypotheses about the evolution of reproductive modes over time.This collaborative effort involves four researchers with extensive experience in diverse areas of biology. The project provides extensive training of graduate and undergraduate students in wide-ranging aspects of organismal and molecular biology. The fact that Boechera is a close relative of the primary plant model organism Arabidopsis adds to the synergistic value and broader impacts of the research. Lastly, the completion of web resources for the dissemination of information on Boechera will provide a valuable asset for researchers and members of the public interested in these fascinating plants.
开花植物羊栖菜属(Boechera)在北美有110个种和多个濒危类群,经常是植物生态学和进化生物学研究的重点。这样的研究试图了解在一个同时表现出有性和无性繁殖模式的群体中的分化进化和杂交过程。不幸的是,以前对这一群体的研究得出的结论受到了严重限制,因为对其成员之间的系统发育关系缺乏了解。Bailey等人。将结合北美各地的田野调查研究、DNA序列、形态评估和染色体信息,以澄清Boechera物种之间的系统发育关系,建立不同的有性物种和无性物种的数量和分布,并评估物种边界。由此产生的系统发育树将被用来检验关于生殖模式随时间演变的假说。这项合作工作涉及四名在不同生物学领域拥有丰富经验的研究人员。该项目为研究生和本科生提供广泛的有机体和分子生物学方面的培训。Boechera是主要植物模式生物拟南芥的近亲,这一事实增加了这项研究的协同价值和更广泛的影响。最后,用于传播有关Boechera的信息的网络资源的完成将为研究人员和对这些迷人的植物感兴趣的公众提供宝贵的资产。
