The efficiency of light interception and of partitioning of photoassimilate into the harvested components of the major food crops appears to have been fully optimised. Nevertheless, there is still very significant scope for increasing crop productivity by increasing the conversion efficiency of photosynthesis by decreasing the proportion of assimilated carbon that is lost through simultaneous metabolic processes. One such process, photorespiration, is in principle completely expendable and yet can account for assimilate losses of 25-50%. The objective of this proposal is to introduce a cyanobacterial carboxysome-based CO2 concentrating mechanism into the chloroplasts of a model C3 plant (tobacco) in order to reduce, or eliminate, photorespiration. This objective will be addressed using a multidisciplinary approach, through the collaboration of several research groups, each contributing complementary expertise in the essential areas of carboxysome genetics and assembly, plant transformation, photosynthetic systems modelling and physiological and biochemical characterisation of whole plant and component photosynthetic processes. The progress and outcomes from the project will be made available to breeders and to the scientific community, with data being presented on the project website, at scientific meetings, at stakeholder events and in peer reviewed publications

光截距的效率和将光剂量分配到主要食品作物的收获成分中的效率似乎已经完全优化。然而，通过减少通过同时代谢过程损失的同化碳的比例来提高光合作用的转化效率，仍然存在着非常显着的提高作物生产率的范围。这样一个过程，即光呼吸，原则上是完全可以消耗的，但可以占25-50％的同化损失。该提案的目的是将基于氰基羧基羧基的二氧化碳浓缩机制引入型号C3植物（烟草）的叶绿体中，以减少或消除光吸光。通过多个研究小组的合作，将使用多学科方法来解决这个目标，每个研究小组都在羧基遗传学和组装，植物转化，光合系统建模以及整个植物和成分光合作用过程的生理和生理学特征的基本领域中提供互补的专业知识。该项目的进度和成果将向育种者和科学界提供，并在项目网站上，科学会议，利益相关者活动和同行评审出版物中提供数据。
