The growth rate of the human population is faster than improvements in crop yields. To feed people in the future, multiple strategies are required. One proposed approach is to raise the yield potential of C(3) crops by modifying photosynthesis to the more efficient C(4) pathway. Owing to complex changes associated with C(4) photosynthesis, it is no understatement to define this conversion as one of the Grand Challenges for Biology in the 21st Century. Here we outline the challenges of installing a C(4) system and assess how new approaches and knowledge may help achieve this goal.
人口增长率超过了作物产量的提高速度。为了在未来养活更多的人，需要采取多种策略。一种被提议的方法是通过将光合作用修改为更有效的 C(4)途径来提高 C(3)作物的产量潜力。由于与 C(4)光合作用相关的复杂变化，可以毫不夸张地将这种转化定义为 21 世纪生物学的重大挑战之一。在这里，我们概述了安装 C(4)系统的挑战，并评估了新方法和知识如何帮助实现这一目标。
