光合作用是地球上最大的物质和能量转换过程,是几乎所有生物活动的物质基础。在光合作用过程中将吸收的光能转化为能量物质的效率与理论值相比非常低。本文从光合作用的重要性出发,从多个角度综述了提高光合效率的最新研究进展。提高光合效率的主要途径是优化光反应,包括增加光吸收和转换、加速非光化学猝灭的恢复、修饰卡尔文循环中的酶、在C3植物中引入碳浓度机制、重建光呼吸途径、从头合成、改变气孔导度等。这些进展表明,光合作用还有很大的改进空间,为提高作物产量和减缓气候条件变化提供了支持。
Photosynthesis is the largest mass- and energy-conversion process on Earth, and it is the material basis for almost all biological activities. The efficiency of converting absorbed light energy into energy substances during photosynthesis is very low compared to theoretical values. Based on the importance of photosynthesis, this article summarizes the latest progress in improving photosynthesis efficiency from various perspectives. The main way to improve photosynthetic efficiency is to optimize the light reactions, including increasing light absorption and conversion, accelerating the recovery of non-photochemical quenching, modifying enzymes in the Calvin cycle, introducing carbon concentration mechanisms into C3 plants, rebuilding the photorespiration pathway, de novo synthesis, and changing stomatal conductance. These developments indicate that there is significant room for improvement in photosynthesis, providing support for improving crop yields and mitigating changes in climate conditions.
