Cooperative Research Visit - Japan: Photosynthetic Competency in Light-grown Leaves

该奖项由美日光转化与光合作用合作项目资助，将使威斯康星大学的Judith Croxdale博士和位于日本筑波的日本国立环境研究所的Kenji Omasa博士能够进行合作研究。在这项研究中，研究人员将研究光生长叶片光合作用过程中成分组合的顺序和时间。利用非破坏性的方法，通过测量叶绿素荧光瞬态来评估光合系统的反应，并通过红外热成像来评估气孔打开。这些测量将使用最近开发的设备，该设备与提供原位测定的数字成像系统相连接。Omasa博士在他位于日本环境厅国家环境研究所的实验室开发了这种新仪器。克罗克斯代尔博士将提供实验叶片材料和光生长叶片的结构和生化分化数据。

This award, supported under the U.S.-Japan Program of Cooperation in Photoconversion and Photosynthesis, will enable collaborative research between Dr. Judith Croxdale of the University of Wisconsin and Dr. Kenji Omasa of the Japanese National Institute for Environmental Studies in Tsukuba, Japan. During this research the investigators will study the sequence and timing of component assemblage as photosynthesis develops in light-grown leaves. Using non-destructive methods, reactions of the photosynthetic system will be evaluated by the measurement of chlorophyll fluorescence transients, and stomatal opening will be assessed by infrared thermography. These measurements will be made using recently developed equipment that is interfaced with a digitial imaging system which provides in situ determinations. Dr. Omasa has developed the new instrumentation at his laboratory at the National Institute for Environmental Studies of the Japan Environment Agency. Dr. Croxdale will provide the experimental leaf material and the data on structural and biochemical differentiation of light-grown leaves.
