The growth of crops on our fields is not only limited by carbon uptake but also carbon retention. Up to half of the carbon gained by photosynthesis during the day is lost at night due to respiration, as carbon dioxide. This project aims to find ways to reduce losses of carbon during the night. One approach will be to investigate re-fixing respired carbon dioxide before it escapes from the leaf and making it available again to photosynthesis during the day. The other approach will aim to find more efficient metabolic pathways that lose less carbon dioxide.

我们田里农作物的生长不仅受到碳吸收的限制，而且还受到碳保持的限制。白天通过光合作用获得的碳中，有多达一半在晚上由于呼吸作用而损失掉，成为二氧化碳。该项目旨在寻找减少夜间碳损失的方法。一种方法是研究在呼吸的二氧化碳从树叶中逸出之前重新固定，并使其在白天重新进行光合作用。另一种方法将致力于寻找更有效的代谢途径，减少二氧化碳的损失。
