项目摘要
ABSTRACTThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Understanding the barriers to reproduction between species is central to evolutionary biology. The evolution of reproductive barriers is a key step in the accumulation of genetic differences among populations of plants and animals, ultimately leading to the formation of new species. By understanding mechanisms of reproductive isolation, broad insight into the origins and maintenance of biological diversity can be gained. This research focuses on reproductive isolation between closely related native plant species that exhibit a common form of reproductive isolation due to competition among male gametes (pollen) during pollination. This research will identify the molecules that are responsible for pollen competition, revealing how these molecules contribute to reproductive isolation among species. The work integrates classical genetic approaches, state of the art technologies, and powerful statistical analyses in a collaboration building on the strengths of two researchers at separate institutions. It has the potential to transform the study of the molecules responsible for reproductive isolation and speciation.This work will train graduate and undergraduate students in modern tools of biological research. Students from groups currently under-represented in the sciences will be targeted using existing recruitment tools and aspects of these studies will contribute to existing programs enhancing K-12 science. In addition, because this work develops novel methods for identifying the causes and consequences of reproductive isolation, it may lead to new approaches in solving issues in the fields of human reproductive health.
该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。了解物种间繁殖的障碍是进化生物学的核心。生殖障碍的进化是植物和动物种群之间遗传差异积累的关键一步,最终导致新物种的形成。通过了解生殖隔离的机制,可以更广泛地洞察生物多样性的起源和维持。这项研究的重点是近缘关系密切的本土植物物种之间的生殖隔离,这些物种由于授粉过程中雄配子(花粉)之间的竞争而表现出一种常见的生殖隔离形式。这项研究将确定负责花粉竞争的分子,揭示这些分子如何导致物种之间的生殖隔离。这项工作将经典的遗传方法、最先进的技术和强大的统计分析结合在一起,建立在两个不同机构的研究人员的优势之上。它有可能改变负责生殖隔离和物种形成的分子的研究。这项工作将培训研究生和本科生现代生物学研究工具。来自目前在科学领域代表性不足的群体的学生将使用现有的招生工具进行定位,这些研究的各个方面将有助于现有的计划,加强K-12科学。此外,由于这项工作为确定生殖隔离的原因和后果开发了新的方法,它可能会导致解决人类生殖健康领域问题的新方法。
