An intriguing set of membrane transport proteins that accumulate bicarbonate into marine cyanobacterial cells will be investigated. These proteins support the crucial process of photosynthetic carbon dioxide fixation in marine cyanobacteria (blue-green algae), which are major contributors to global carbon dioxide sequestration and form one of the foundations of the marine food web. These bicarbonate "transporters" will also be transferred into a model plant system to test whether the efficiency of photosynthesis can be improved, with corresponding gains in the water-use efficiency of these plants. If successful this technology will have profound global implications for improving crop production in semi-arid areas.

一组有趣的膜转运蛋白积累到海洋蓝藻细胞碳酸氢盐将进行调查。 这些蛋白质支持海洋蓝细菌（蓝绿藻）光合作用二氧化碳固定的关键过程，这是全球二氧化碳封存的主要贡献者，并构成海洋食物网的基础之一。这些碳酸氢盐“转运蛋白”也将被转移到一个模型植物系统中，以测试光合作用的效率是否可以提高，这些植物的水利用效率也会相应提高。 如果成功，这项技术将对改善半干旱地区的作物生产产生深远的全球影响。
