9726511 BOHS Molecular Phylogenetic Studies in the genus Solanum (Solanaceae) Lynn A. Bohs The tomato family (Solanaceae) is one of world's most economically important plant groups, and many of these species have been introduced throughout the world from the Americas. Familiar members of the family include the tomato, potato, and eggplant, as well as other minor food crops and tobacco. Certain species are sources of foods, ornamental plants, and medicinally valuable or poisonous alkaloids. Solanum, one of the largest genera of any plant family, has about 1500 species throughout the world, but species are most numerous in the New World tropics. Solanum exhibits a remarkable diversity in morphology, biochemistry, reproductive systems, and dispersal patterns that make it ideal group for evolutionary studies. Because the understanding of the classification and evolution of Solanum is very limited, the ability of agriculturists and scientists to utilize species of economic and scientific interest is hindered. Dr. Bohs will use two molecular data sets, one from the chloroplast genome and one from the nuclear ribosomal DNA, to examine evolutionary relationships across the taxonomic spectrum of the entire genus. This study will arrive at a classification framework that can be used to guide more detailed studies at lower taxonomic levels. Questions concerning biogeographic patterns, breeding system evolution, and fruit morphology and dispersal will be examined in a phylogenetic context. A field trip to Bolivia is planned to collect unusual and poorly known representatives of Solanum that will enhance our knowledge of morphological evolution and species diversity in this large and important genus.

9726511 Bohs 茄属（茄科）分子系统学研究Bohs 番茄科（Solanaceae）是世界上经济上最重要的植物类群之一，并且这些物种中的许多已经从美洲引入世界各地。 常见的家庭成员包括番茄，马铃薯和茄子，以及其他次要粮食作物和烟草。 某些物种是食物、观赏植物和药用价值或有毒生物碱的来源。 茄属是植物科中最大的属之一，全世界约有1500种，但在新世界热带地区的种类最多。 茄属植物在形态学、生物化学、生殖系统和传播模式上表现出显著的多样性，使其成为进化研究的理想类群。 由于对茄属植物的分类和进化的了解非常有限，农业学家和科学家利用具有经济和科学价值的物种的能力受到阻碍。 Bohs博士将使用两个分子数据集，一个来自叶绿体基因组，一个来自核核糖体DNA，来研究整个属的分类谱的进化关系。 这项研究将得出一个分类框架，可用于指导更详细的研究，在较低的分类水平。有关生物地理模式、繁殖系统进化以及果实形态和传播的问题将在系统发育背景下进行研究。 计划到玻利维亚进行实地考察，以收集不寻常和鲜为人知的茄属代表，这将提高我们对这一大型重要属的形态进化和物种多样性的认识。
