NSF/Alfred P. Sloan Foundation Postdoctoral Research Fellowship in Molecular Evolution for FY 1997

摘要 DBI 9750012 Paulyn Cartwright 这一行动为1997年的NSF/Alfred P. Sloan分子进化博士后研究奖学金提供资金。 这些奖学金支持研究涉及的理论，比较，计算，和/或实验分析的生物模式和过程在分子水平的框架内器官的进化变化和适应。 这些研究还包括使用分子数据来解决更广泛的进化问题。 每项研究金资助一项研究和培训计划，该计划将在一个赞助实验室进行。 该奖学金的研究和培训计划题为“开花植物进化中性别决定的分子机制”。“它解决了玉米中涉及基因TASSELSEED 2的雄性性别决定机制是否在其他草种中起作用。 该研究涉及表征发育形态，雌性器官流产的性质和时间，以及TASSELSEED 2在几种草种中的表达。 这一信息，映射到一个基因组，将解决是否相同的机制是参与进化的重复发生的字符，是一个重要的第一步，在了解开花植物性别决定的分子机制。

Abstract DBI 9750012 Paulyn Cartwright This action funds an NSF/Alfred P. Sloan Postdoctoral Research Fellowship in Molecular Evolution for 1997. These fellowships support studies involving the theoretical, comparative, computational, and/or experimental analyses of biological patterns and processes at the molecular level within the framework of organismic evolutionary change and adaptation. These studies also include the use of molecular data to address broader evolutionary questions. Each fellowship supports a research and training plan to be carried out in a sponsoring laboratory. The research and training plan for this fellowship is entitled "The Molecular Mechanisms of Sex Determination in the Evolution of Flowering Plants." It addresses whether the male sex determining mechanism involving the gene TASSELSEED 2 in maize operates in other grass species. The research involves characterizing the developmental morphology, the nature and timing of female organ abortion, and TASSELSEED2 expression in several grass species. This information, mapped onto a phylogeny, will address whether or not the same mechanism is involved in the evolution of re-occurring character and is an important first step in understanding the molecular mechanisms underlying sex determination in flowering plants.
