0340609RascherThis award supports Uwe Rascher and students from Columbia University in a collaboration with Achim Walter of the Institute of Phytosphere Research at the Foschungszentrum Juelich, Germany. The research will focus on photosynthesis and growth as key processes in determining the overall performance of plants and ecosystems. Both processes are dynamic, heterogeneous in space and time, and depend on a spectrum of environmental factors. Currently empirical connections between growth processes of different organs are established and can be used for scaling between different levels of plant organization. The central aims of this project are to evaluate the range of dynamic growth distributions within the canopy of different model species; to analyze leaf growth distributions as a function of various environmental factors; to test the correlations between fluctuations of growth, photosynthesis and environmental parameters; and to identify molecular and physiological mechanisms that mediate between photosynthetic energy acquisition and plant growth. A second aim of this project is to facilitate the exchange of young researchers within an established international cooperation between a research institute in Germany and Columbia University's Biosphere 2 Center. Presently, the group investigates interactions between growth and photosynthesis of plants and plant communities as quantified by non-destructive, novel imaging techniques and determines the underlying physiological processes.

0340609Rascherthis Award与哥伦比亚大学的Uwe Rascher和学生与德国Foschungszentrum Juelich的植物学研究所的Achim Walter合作。 该研究将集中于光合作用和增长，作为确定植物和生态系统整体性能的关键过程。 这两个过程都是动态的，在空间和时间上是异质的，并且取决于环境因素的范围。 目前，建立了不同器官的增长过程之间的经验联系，可用于在不同级别的植物组织之间进行扩展。 该项目的中心目的是评估不同模型物种冠层内动态增长分布的范围；分析叶片生长分布与各种环境因素的关系；测试生长，光合作用和环境参数的波动之间的相关性；并确定分子和生理机制在光合作用获取和植物生长之间进行介导。 该项目的第二个目的是在德国研究所与哥伦比亚大学的生物圈2中心之间建立的国际合作中促进年轻研究人员的交流。 目前，该小组调查了通过非破坏性，新颖的成像技术量化的植物和植物群落的生长与光合作用之间的相互作用，并确定了基本的生理过程。
