Collaborative Research: Ecological Genetics of Response to Light in Arabidopsis thaliana (Brassicaceae)

9509239施密特我们建议通过实验确定植物形态如何响应模式植物系统拟南芥中光可用性的变化而变化。 光的可利用性将通过操纵拟南芥的遗传同质系的植物密度来改变。 我们将确定是否响应于低光的形态变化增加植物在这种条件下存活和产生后代的概率。 我们还将研究A. thaliana不同的光条件，以确定哪些基因是负责这种形态变化。 这项研究将更好地了解压力对植物进化的影响，并对培育在拥挤条件下表现良好的作物具有意义。

9509239 SCHMITT We propose to experimentally determine how plant morphology changes in response to variation in light availability in the model plant system, Arabidopsis thaliana. Light availability will be varied by manipulating plant density of genetically homogenous lines of Arabidopsis. We will determine whether morphological changes in response to low light increase the probability of a plant surviving and producing offspring under such conditions. We will also investigate the response of several mutants of A. thaliana to different light conditions to determine which genes are responsible for this morphological change. This research will provide a better understanding of the effect of stress on plant evolution, and it has implications for breeding crops that perform well in crowded conditions.
