The enhancement of the photosynthetic capacity of crops by the expression of more efficient Rubisco versions has been a main target in the field of plant photosynthesis improvement. However, such an increase in the photosynthetic efficiency will depend on the environmental conditions and on the responsiveness of Rubisco to temperature and CO2 availability. After an exhaustive compilation and standardization of the data published so far, a large natural variability in the thermal responses of Rubisco kinetic parameters in higher plant species was revealed. The variability observed was related to the photosynthetic type but a limited adaptation to the species thermal environment was found. We provide theoretical evidence that the existence of distinctive Rubisco responses to varying temperature and CO2 concentration constitutes a promising avenue for increasing the photosynthetic capacity of important crops under future climatic conditions.

通过利用Rubisco催化性状的温度响应的自然变化，可以潜在地改善作物的光合作用CO2同化。

通过表达更有效的Rubisco版本来增强作物的光合作用能力已经成为植物光合作用改善领域中的主要目标。但是，这种光合作用效率的提高将取决于环境条件以及Rubisco对温度和CO2利用率的响应度。经过详尽的汇编和迄今公布的数据的标准化，揭示了高等植物物种中Rubisco动力学参数的热响应具有很大的自然变异性。观察到的变异性与光合类型有关，但发现对物种热环境的适应性有限。
