This project aims to use state-of-the-art technologies to develop a novel framework that links a super-charged version of photosynthesis (known as C4 photosynthesis) to changes in nocturnal leaf respiration. A quarter of global land photosynthesis occurs in C4 plants that include several important cereal crops. Although advances have been made in modelling C4 photosynthesis, these advances are unable to model variations in nocturnal respiration. Expected outcomes include equations that predict respiration in C4 plants growing in current/future climates. Benefits to include knowledge needed to engineer faster-growing crops and providing climate modelers the ability to more accurately predict carbon exchange in C4-dominated ecosystems.

该项目旨在利用最先进的技术开发一种新的框架，将光合作用的超高能量版本(称为C4光合作用)与夜间叶片呼吸的变化联系起来。全球四分之一的陆地光合作用发生在C4植物中，其中包括几种重要的谷类作物。尽管在模拟C4光合作用方面取得了进展，但这些进展不能模拟夜间呼吸作用的变化。预期结果包括预测在当前/未来气候条件下生长的C4植物的呼吸作用的方程式。好处包括设计生长更快的作物所需的知识，并使气候建模人员能够更准确地预测以C4为主的生态系统中的碳交换。
