This award supports cooperative research in the regulation and reaction mechanisms of key enzymes in photosynthesis to be carried out by Gerald Edwards of Washington State University along with Marion O'Leary of the University of Nebraska Department of Biochemistry and two researchers from the Department of Biochemistry at the University of Rosario in Argentina, Carlos Andreo and Alberto Iglesias. Photosynthesis is of fundamental importance as a biological process and this study will focus on carbon-4 photosynthesis and its mechanism and control by intrinsic and environmental factors. The primary role of the Argentinian team will be to apply their expertise in enzyme purification, quarternary structure and the identification of functional groups. The U.S. scientists will identify cold-tolerant varieties of important crops, synthesize substrate analogs and locate the position of functional groups on enzymes. Thus the complementary expertise of three laboratories will study the key enzymes of the C-4 pathway of photosynthesis which allows crops to assimilate carbon dioxide at high rates under optimum conditions.

该奖项支持华盛顿州立大学的Gerald Edwards与内布拉斯加大学生物化学系的Marion O 'Leary以及阿根廷罗萨里奥大学生物化学系的两位研究人员卡洛斯Andreo和Alberto Iglesias在光合作用中关键酶的调节和反应机制方面进行的合作研究。光合作用作为一个生物学过程具有根本的重要性，本研究将集中在碳-4光合作用及其机制和内在和环境因素的控制。阿根廷团队的主要作用将是运用他们在酶纯化、四级结构和官能团鉴定方面的专业知识。美国科学家将鉴定重要作物的耐寒品种，合成底物类似物，并确定酶上官能团的位置。因此，三个实验室的互补专业知识将研究光合作用的C-4途径的关键酶，使作物在最佳条件下以高速率吸收二氧化碳。
