9317775 Smith The Gesneriaceae, the African-violet family of plants, is a mostly tropical group in the New and Old Worlds, little known biologically except for those species prized as ornamentals. Dr. James Smith of Boise State University has pioneered the application of new DNA-based methods of analysis to problems of taxonomic delimitation and phylogenetic reconstruction in this family. With assistance from undergraduate students in research, he is exploring phylogenetic relationships in representative species of all tribes and most genera of the family, using traditional morphological characters and new evidence from chloroplast DNA. Concordance in these independent datasets will lay the basis for detailed studies of biogeography and of the evolution of pollination systems. The comparison and integration of data from different sources constitute an important arena of contemporary phylogenetic research. Taxa from predominantly tropical regions are rarely explored as model systems in this debate, because in general they are poorly known. The RUI project by Dr. James Smith will contribute new DNA data and refined morphological insights to the study of Gesneriaceae in particular and to taxonomic methodology in general.

9317775史密斯苦苣苔科植物是非洲紫罗兰科植物，是新大陆和东半球的一个主要热带类群，除了那些被珍视为观赏植物的物种外，在生物学上鲜为人知。博伊西州立大学的詹姆斯·史密斯博士率先将基于DNA的新分析方法应用于该家族的分类划分和系统发育重建问题。在本科生的帮助下，他正在利用传统的形态特征和来自叶绿体DNA的新证据，探索该科所有部落和大多数属的代表性物种的系统发育关系。这些独立数据集的一致性将为详细研究生物地理学和授粉系统的进化奠定基础。不同来源的数据的比较和整合构成了当代系统发育研究的一个重要领域。在这场辩论中，主要来自热带地区的分类群很少被作为模式系统来探索，因为总的来说，它们鲜为人知。詹姆斯·史密斯博士的RUI项目将为苦瓜科的研究和分类学方法论的研究贡献新的DNA数据和精炼的形态见解。
