RUI: Defining the genetic architecture underlying nonrandom mating in Arabidopsis thaliana

RobertJ. SwansonIOS-1020325 RUI：定义拟南芥非随机交配的遗传结构众所周知，开花植物在繁殖上不是不加选择的。散布在柱头上的花粉是一种混合物，其比例通常与后代的比例不匹配。 换句话说，一些花粉有更大的交配成功率，这种现象称为非随机交配。非随机交配在生物界中具有显著的进化意义。然而，显花植物非随机交配的遗传学还不太清楚。本计画将利用模式植物拟南芥的工具来定义引导非随机交配的遗传因子。 更全面地了解植物受精的遗传学是促进农业施肥操作的必要条件。最后，本项目提出的方法要求在初级本科院校培训本科生;这项工作将加强该院校的研究和教学基础设施，并为本科生提供使用尖端技术的研究培训。 这类工作具有很大的潜力，可以让学生接触和招募他们从事研究工作。

Robert J. SwansonIOS-1020325RUI: Defining the genetic architecture underlying nonrandom mating in Arabidopsis thalianaIt is well known that flowering plants are not reproductively indiscriminate. The pollen dusted across flower stigmas is a mixture, whose proportions do not often match proportions within progeny. In other words, some pollen have greater mating success, a phenomenon called nonrandom mating. Nonrandom mating has striking evolutionary significance in organisms across kingdoms. The genetics of nonrandom mating in flowering plants, however, is less well understood. This project will exploit tools available for the model plant Arabidopsis thaliana to define the genetic elements that direct nonrandom mating. A fuller understanding of the genetics of plant fertilization is required to facilitate the manipulation of fertilization in agriculture. Finally, the approach proposed in this project requires the training of undergraduates at a primary undergraduate institution; this work will enhance the institution's research and teaching infrastructures, and provide undergraduate students with research training using cutting-edge technology. Such work has great potential to expose and recruit students to research professions.
