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.

唇形科（Lamiaceae）内的鼠尾草和近缘植物（开花植物鼠尾草属（Salvia））包括大约1000个物种，包括经济上重要的草本植物鼠尾草和迷迭香，以及许多园林植物。鼠尾草在多种多样的栖息地中发挥着重要的生态作用，包括为蝴蝶和蛾幼虫提供食物，为蜜蜂和其他授粉者提供花蜜来源。 这项研究将重建不同鼠尾草物种之间的系谱关系，并解决有关花的形状和授粉机制的组内的演变的重要问题。本科生，研究生和博士后研究人员在威斯康星州，麦迪逊和内布拉斯加大学科尔尼分校的大学将在广泛的形态学和分子系统技能的培训，和威斯康星州，麦迪逊大学的本科生将获得热带领域的生物学经验，通过一个计划的顶点领域课程。 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公众可访问的数据库更广泛地提供。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。 这些新的遗传学现在提供了一个框架，以调查不同的过程，促进物种的多样化在一个谱系。鼠尾草属（唇形科）具有世界性的分布和多样化的广泛，无论是在物种的数量，和各种花和营养形态存在于组内。 这项研究将调查本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相关。研究人员将对1000种鼠尾草属物种中的约650种进行采样，并使用下一代测序方法，使用450多个核基因和叶绿体基因组来估计鼠尾草属及其近亲之间的系统发育关系。这个系统发育框架，然后将被用来确定的时间和地理位置的物种形成率增加组内。然后，将在鼠尾草属植物的背景下评估关键花特征的形态计量学分析，以检验花特征的进化在该组中作为关键创新的假设。
