0305459StoneThis Americas Program award will support Dr. Judy L. Stone of Colby College, Maine in a research collaboration with Dr. Oscar J. Rocha-Nunez and Dr. Paul Hanson of the Universidad de Costa Rica in San Pedro, Costa Rica. The researchers intend to investigate genetic and ecological forces acting on the evolution of self-fertilization, one of the most common evolutionary transitions in flowering plants. The collaborators propose to expand the knowledge base of self-compatible and self-incompatible plant systems that are important in modeling the evolution of self-fertilization and, ultimately, make contributions to the genetic and ecological factors influencing selection in mating systems. The collaborators will bring complementary skills to the project that will allow them to integrate ecological processes in the field, theoretical predictions of models, and patterns of change for the genes of interest. Stone has expertise in sequencing the gene that controls self-fertilization and in relating changes at the genetic level to changes in ability to self-fertilize, Rocha has expertise in the study of self-fertilization in plants in their natural settings, and Hanson's expertise with insects is needed to determine how differences in insect pollinators will affect the degree of self-fertilization. In addition, the project will help to support the involvement of four undergraduate students from the United States.?????

0305459STONETHIS AMECAS计划奖将在缅因州科尔比学院的Judy L. Stone博士与Oscar J. Rocha-Nunez博士和位于哥斯达黎加San Pedro的Costa Rica大学的Paul Hanson博士进行研究。 研究人员打算研究作用于自我施用进化的遗传和生态力，这是开花植物中最常见的进化转变之一。合作者建议扩大自我兼容和自我兼容的植物系统的知识基础，这些知识基础对于建模自我施用的演变至关重要，并最终为影响交配系统选择的遗传和生态因素做出贡献。 合作者将为项目带来互补的技能，使他们能够将生态过程整合到现场，理论上的模型预测以及感兴趣基因的变化模式。 Stone在测序控制自我征收并将遗传水平的变化与自我施用能力的变化联系起来的基因方面具有专业知识，Rocha在自然环境中植物的自我受精研究方面具有专业知识，以及汉森在汉森的专业知识以及汉森的专业知识需要昆虫来确定昆虫传粉媒介的差异将如何影响自我受精的程度。此外，该项目将有助于支持来自美国的四名本科生的参与。
