U.S.-Japan Cooperative Research (Photoconversion/ Photosynthesis): Mechanism for the Acclimation of Photosynthetic Membranes to the Environment

该奖项将支持加州大学伯克利分校植物生物系Anastasios Melis教授和日本冈崎国立基础生物学研究所细胞生物系Fujita教授之间为期两年的美日合作光转化/光合作用研究计划项目。该项目将侧重于植物和藻类能够调节它们在光系统II(PSII)和光系统I(PSI)中的光合作用单位的大小以及PSII/PSI的比率以应对光照质量的差异的机制。这样的调整不断优化整个植物或植物部分甚至整个生态系统的光合作用能力。这是一个非常重要的问题。这项合作将有助于结合资源的使用，阐明调节叶绿体中光系统化学计量比调节的分子机制。特别是，这项研究将讨论导致光系统化学计量调节的叶绿体中的信号感知和信号转导过程，以及光合原核生物和高等植物中光质和营养有效性对基因表达调控的不同方面。

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.
