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.

Campbell DEB-9806945 该项目将研究大型且重要的玫瑰家族内的进化关系。 这组植物包含许多具有商业价值的水果（苹果、梨、草莓、樱桃、桃子、李子、黑莓和覆盆子）和许多具有重要园艺意义的植物（玫瑰、栒子、斗篷草、缰绳、花榅桲、火刺） 、cinqfoil 等）。 尽管这些植物在我们的日常生活和科学兴趣中发挥着巨大而重要的作用，但我们对该家族成员的进化关系并没有清晰的认识。 造成这种情况的主要原因是没有积累足够的证据来充分解决该问题。 坎贝尔博士项目的主要目的是收集 DNA 序列数据，以提供该群体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，以创建该家族进化关系的整体图景。 这些知识将为研究该科内的关键群体建立一个框架，提供对该科中有趣特征（例如果实）的进化的见解，并有助于我们对植物进化的整体理解。
