9527551 PIGLIUCCI 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.

9527551 PIGLIUCCI 我们建议通过实验确定模型植物系统拟南芥中植物形态如何响应光可用性的变化而变化。 通过控制拟南芥遗传同质品系的植物密度，可以改变光的可用性。 我们将确定响应弱光的形态变化是否会增加植物在这种条件下生存和产生后代的可能性。 我们还将研究拟南芥的几种突变体对不同光照条件的反应，以确定哪些基因导致了这种形态变化。 这项研究将有助于更好地理解胁迫对植物进化的影响，并且对于培育在拥挤条件下表现良好的作物具有重要意义。
