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.

坎贝尔 DEB-9806945 这个项目将调查大而重要的玫瑰家族内部的进化关系。 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，黑莓和乌藨子）和许多园艺上重要的植物（玫瑰，cotoneaster，lady's mantle，bridle-wreath，开花温柏，火棘，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不清楚。 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个问题。 坎贝尔博士项目的一个主要目的是收集DNA序列数据，为这一群体的进化历史提供可靠的编年史。 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，以创建一个家庭进化关系的全貌。 这些知识将建立一个框架，为家庭内的关键群体的研究，提供洞察家庭中有趣的功能（如水果）的演变，并有助于我们的整体理解或植物进化。
