U.S.-France Cooperative Research: Analysis of Gene Expression during Acclimation of Cyanobacteria to Stress Conditions

这项为期三年的奖项旨在表彰美法在海洋微生物生物学领域的合作研究，获奖者包括斯坦福大学华盛顿卡内基研究所的亚瑟·格罗斯曼和一名博士后研究员，以及法国国家科学研究中心罗斯科夫生物站的丹尼尔·沃洛特。他们将合作研究淡水和海洋蓝藻的生理过程以及适应环境变化的控制机制。利用一种被称为差异显示的技术，研究人员建议识别淡水聚球藻和原绿球藻中环境引发的基因表达变化。美国研究人员为这次合作带来了光合细菌的专业知识。法国调查人员在生物海洋学方面的专门知识补充了这一点。他们的合作将推进对蓝藻过程的理解，当环境条件发生变化时，以及这些适应过程如何适应蓝藻可以茁壮成长的不同栖息地。该奖项将支持这一国际合作的增量成本；即赴法国罗斯科夫的旅费和美国研究员、博士后研究员的生活费。

They will collaborate on studies of physiological processes in freshwater and marine cyanobacteria and the control mechanism, which allows acclimation to environmental change. Using a technique known as differential display, the investigators propose to identify environmentally triggered changes in gene expression in freshwater Synechoccus and Prochlorococcus. The U.S. investigators bring to this collaboration expertise in photosynthetic bacteria. This is complemented by the French investigator's expertise in biological oceanography. Their collaboration will advance understanding of the processes in cyanobacteria when environmental conditions are altered and how these acclimation processes are tailored to the diverse habitats in which cyanobacteria can thrive. This award will support the incremental costs of this international collaboration; that is, the travel to Roscoff, France and subsistence expenses of the U.S. investigator and postdoctoral researcher.
