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.

摘要 DBI 9750012 Paulyn Cartwright 这项行动资助了 1997 年 NSF/Alfred P. Sloan 分子进化博士后研究奖学金。这些奖学金支持涉及分子水平上生物模式和过程的理论、比较、计算和/或实验分析的研究在有机体进化变化和适应的框架内。 这些研究还包括使用分子数据来解决更广泛的进化问题。 每项奖学金都支持在赞助实验室中进行的研究和培训计划。 该奖学金的研究和培训计划的标题是“开花植物进化中性别决定的分子机制”。 它探讨了玉米中涉及 TASSELSEED 2 基因的雄性性别决定机制是否在其他禾本科植物中起作用。 该研究涉及几种草类的发育形态、雌性器官流产的性质和时间以及 TASSELSEED2 表达的特征。 这些信息映射到系统发育上，将解决重复出现的特征的进化是否涉及相同的机制，并且是理解开花植物性别决定的分子机制的重要的第一步。
