This award will support a two-year U.S.-Japan Cooperative Photoconversion/Photosynthesis Research Program project between Professor Anastasios Melis, Department of Plant Biology, University of California Berkeley, and Professor Yoshihiko Fujita, Department of Cell Biology, National Institute for Basic Biology, Okazaki, Japan. The project will focus on the mechanism by which plants and algae are capable of adjusting both the size of their photosynthetic units in photosystem-II (PSII) and photosystem- I (PSI), as well as the ratio of PSII/PSI in response to differences in the quality of illumination. Such ajustments constantly optimize the photosynthetic capability of whole plants or plant parts and even whole ecosystems. This is a very important question. The collaboration will help combine the use of resources in elucidating the molecular mechanism that regulates photosystem stoichiometry adjustments in chloroplasts. In particular, the research will address the processes of signal perception and signal transduction in the chloroplasts leading to photosystem stoichiometry adjustments, and on different aspects of the regulation of gene expression by light-quality and nutrient availability in photosynthetic prokaryotes and higher plants.

该奖项将支持为期两年的美国-日本合作社 光转换/光合作用研究计划项目 Anastasios Melis教授，植物生物学系， 加州伯克利大学教授藤田佳彦， 国立基础生物学研究所细胞生物学部门， 日本冈崎市。 该项目将侧重于该机制， 这些植物和藻类能够调节 光系统II（PSII）和光系统- I（PSI），以及响应差异的PSII/PSI比率 在照明的质量。 这样的调整不断优化 整个植物或植物部分的光合能力， 甚至整个生态系统。 这是一个非常重要的问题。 这项合作将有助于联合收割机将资源的使用结合起来， 阐明调节光系统的分子机制 叶绿体中化学计量的调整。 特别是 研究将解决信号感知和信号的过程， 叶绿体中的转导导致光系统 化学计量调整，并在不同方面的 光质和养分对基因表达的调控 在光合原核生物和高等植物中的可用性。
