Photosynthesis – the conversion of energy from sunlight into chemical energy – is essential for life on Earth. Yet there is much we do not understand about photosynthetic energy conversion on a fundamental level: how it evolved and the extent of its diversity, its dynamics, and all the components and connections involved in its regulation. In this commentary, researchers working on fundamental aspects of photosynthesis including the light-dependent reactions, photorespiration, and C4 photosynthetic metabolism pose and discuss what they view as the most compelling open questions in their areas of research.

照亮道路：光合作用研究中引人注目的开放性问题


光合作用——将阳光的能量转化为化学能——对于地球上的生命至关重要。然而，对于光合能量转换，我们在基本层面上还有很多不了解的地方：它是如何进化的、其多样性的程度、它的动态以及参与其调节的所有组成部分和联系。在这篇评论中，研究光合作用基本方面（包括光依赖性反应、光呼吸和 C4 光合作用代谢）的研究人员提出并讨论了他们认为在其研究领域中最引人注目的开放性问题。
