Molecular Phylogenetic Studies in Rosaceae

Campbell DEB-9806945这个项目将研究大型和重要的玫瑰家族内的进化关系。这组植物包括许多有商业价值的水果(苹果、梨、草莓、樱桃、桃子、李子、黑莓和覆盆子)和许多在园艺上有重要意义的植物(玫瑰、椰子、淑女披风、缰绳花环、开花的木瓜、火刺、朱砂等)。尽管这些植物在我们的日常生活和科学兴趣中扮演着巨大而重要的角色，但我们对该家族成员的进化关系并没有一个清晰的看法。造成这种情况的一个主要原因是，没有积累足够的证据来充分解决这一问题。坎贝尔博士项目的一个主要目标是收集DNA序列数据，以提供这个群体中进化历史的可靠编年史。这些数据将与坎贝尔博士和其他研究人员积累的结构、化学和其他数据进行比较，以创建家庭进化关系的总体图景。这些知识将为研究该家族中的关键群体建立一个框架，为该家族中有趣的特征(如果实)的进化提供洞察力，并有助于我们对植物的整体理解或进化。

Campbell DEB-9806945 This project will investigate the evolutionary relationships within the large and important rose family. This group of plants contains numerous commercially valuable fruits (apples, pears, strawberries, cherries, peaches, plums, blackberries, and raspberries) and many horticulturally significant plants (roses, cotoneaster, lady's mantle, bridle-wreath, flowering quince, fire-thorn, cinqfoil, and others). Despite the large and important role that these plants play in our daily lives and scientific interest, we do not have a clear view of the evolutionary relationships of members of the family. A primary reason for this situation is that insufficient evidence has been accumulated to adequately address the problem. A primary aim of Dr. Campbell's project is to gather DNA sequence data to provide a reliable chronicle of evolutionary history in this group. These data will be compared with structural, chemical, and other data that have been accumulated by Dr. Campbell and other researchers to create an overall picture of evolutionary relationships in the family. Such knowledge will establish a framework for studies of key groups within the family, provide insights into the evolution of interesting features in the family (such as the fruits), and contribute to our overall understanding or plant evolution.
