This award supports a doctoral dissertation enhancement project that examines genetic variability in the molecular basis of self-incompatibility (i.e., the ability of plants to recognize and reject their own pollen) in the genus Coffea, the economically important genus of coffee trees. A second line of research will examine evolutionary transitions in self-incompatibility that are putatively associated with ancient island colonization by coffee trees endemic to Madagascar and the Mascarene Islands (Mauritius and Reunion). The resulting data will be used to test whether Madagascan coffee was an exception to Baker's Rule (that self-incompatible taxa cannot colonize islands).This project will enable a U.S. graduate student to undertake a project jointly developed and conducted with international collaborators, including scientists and students in Madagascar and Mauritius, as well as in the United Kingdom. The project will involve field experiments and collections of coffee trees in Madagascar, Mauritius and Reunion, and in each country a resident student will gain experience in designing and executing field experiments and collecting plants for herbariums. The project will strengthen international collaborations between U.S. and African scientists and will provide opportunities to share molecular genetic and computational expertise with host countries.

该奖项支持博士学位论文增强项目，该项目在自我兼容性的分子基础上检查遗传变异性（即植物识别和拒绝其自己的花粉的能力），这是咖啡园的经济重要属。第二条研究将检查自我兼容性的进化转变，这与马达加斯加和玛斯卡雷群岛（Mauritius and Cerunion）特有的咖啡树殖民化相关。 由此产生的数据将用于测试马达加斯加咖啡是否是贝克统治的例外（自我兼容的分类单元不能殖民岛屿）。该项目将使美国研究生能够与包括科学家在内的国际合作者进行一项项目，包括科学家在内以及马达加斯加和毛里求斯的学生以及英国。该项目将涉及马达加斯加，毛里求斯和聚会的咖啡树实验和集合，在每个国家，一个居民的学生将获得设计和执行现场实验并为植物标本室收集植物的经验。该项目将加强美国和非洲科学家之间的国际合作，并将提供与东道国共享分子遗传和计算专业知识的机会。
