项目摘要

Sages and relatives (the flowering plant genus Salvia) within the mint family (Lamiaceae) comprises approximately 1000 species, including the economically important herbs sage and rosemary, in addition to many garden ornamentals. Sages play important ecological roles in a diversity of habitats, including providing food for butterfly and moth larvae, and nectar sources for bees and other pollinators. This study will reconstruct genealogical relationships among different sage species, and address important questions concerning the evolution of flower shape and pollination mechanisms within the group. Undergraduates, graduate students, and post-doctoral researchers at the University of Wisconsin, Madison and University of Nebraska at Kearney will be trained in a broad range of morphological and molecular systematic skills, and University of Wisconsin, Madison undergraduate students will gain tropical field biology experience through a planned capstone field course. Information about Salvia will be disseminated through a project website geared towards professional botanists and sage enthusiasts, while other project data will be presented more broadly through publically-accessible databases. The ability to reconstruct phylogenetic relationships using genome-wide DNA sequence data and powerful computational resources has revolutionized the field of systematics. These new phylogenies now provide a framework to investigate the different processes that facilitate the diversification of species within a lineage. Salvia (Lamiaceae) has a worldwide distribution and diversified extensively, both in terms of the number of species, and the variety of floral and vegetative morphologies present within the group. This research will investigate the evolution of the unique staminal feature present in members of the genus, and test whether the origin of this character is correlated with an increase in rates of speciation. Researchers will sample about 650 of the 1000 described Salvia species and use Next Generation Sequencing approaches to estimate phylogenetic relationships among Salvia and close relatives using over 450 nuclear genes and the chloroplast genome. This phylogenetic framework will then be used to determine the timing and biogeographic location of increased rates of speciation within the group. Morphometric analyses of key floral features will then be evaluated within the context of the Salvia phylogeny to test the hypothesis that the evolution of floral features have served as key innovations within the group.

薄荷科（Lamiaceae）中的鼠尾草及其近亲（开花植物鼠尾草属）大约有1000种，包括经济上重要的草药鼠尾草和迷迭香，以及许多花园观赏植物。鼠尾草在多种栖息地中扮演着重要的生态角色，包括为蝴蝶和蛾子幼虫提供食物，为蜜蜂和其他传粉媒介提供花蜜。本研究将重建不同鼠尾草物种间的系谱关系，并探讨鼠尾草类群内花形进化和传粉机制等重要问题。威斯康星大学麦迪逊分校和内布拉斯加州大学科尔尼分校的本科生、研究生和博士后研究人员将接受广泛的形态学和分子系统技能培训，威斯康星大学麦迪逊分校的本科生将通过计划中的顶点课程获得热带野外生物学经验。有关鼠尾草的信息将通过一个面向专业植物学家和鼠尾草爱好者的项目网站传播，而其他项目数据将通过可公开访问的数据库更广泛地呈现。利用全基因组DNA序列数据和强大的计算资源重建系统发育关系的能力已经彻底改变了系统学领域。这些新的系统发生学现在提供了一个框架来研究促进一个谱系内物种多样化的不同过程。鼠尾草科（Lamiaceae）在世界范围内分布广泛，种类繁多，植物和营养形态多样。本研究将探讨该属成员中存在的独特雄蕊特征的进化，并测试这种特征的起源是否与物种形成率的增加有关。研究人员将对1000种鼠尾草中的650种进行采样，并使用下一代测序方法利用450多个核基因和叶绿体基因组来估计鼠尾草及其近亲之间的系统发育关系。这一系统发育框架将用于确定种群内物种形成速率增加的时间和生物地理位置。然后将在鼠尾草系统发育的背景下评估关键花特征的形态计量学分析，以验证花特征的进化是该群体中关键创新的假设。
