Photosynthetically active bicarbonate transporters from cyanobacteria & their rational redesign for application in engineered crops that use less water.

海洋蓝绿藻是全球初级生产力和渔业生产力的重要组成部分，但对这些生物体的CO2获取过程知之甚少。我们的目的是确定蛋白质结构和监管控制存在于两个类的蓝藻碳酸氢盐转运所需的高效光合作用。这些信息现在对于我们重新设计这些碳酸氢盐转运蛋白的目标至关重要，因此它们将在植物中发挥作用，从而有助于工程作物植物的应用目标，这些作物植物可以产生良好的谷物产量，减少对水的需求。

Marine blue-green algae are critical components of global primary productivity and fisheries productivity but CO2 acquisition processes in these organisms are poorly understood. Our aim is to determine the protein structure and regulatory controls present in two classes of cyanobacterial bicarbonate transporters that are required for efficient photosynthesis. This information is now critical to the our goal of redesigning these bicarbonate transporters so they will be functional in plants, thereby contributing to the applied objective of engineering crop plants that could produce good grain yields with reduced water requirements.
