反式类囊体质子动力（pmf）的形成与光驱动电子转移相耦合，两者都为ATP的合成提供动力，并作为启动天线调节的信号。这一关键中间体由于其短暂和多变的性质而难以研究。这篇综述涵盖了最近在体内探索pmf的努力，以及解决光合作用中的一个关键问题：光合机制如何在不同的环境中实现足够的灵活性来满足植物的能量和调节需求？结论是，pmf在这些灵活机制中起着核心作用。
The formation of trans-thylakoid proton motive force (pmf) is coupled to light-driven electron transfer and both powers the synthesis of ATP and acts as a signal for initiating antenna regulation. This key intermediate has been difficult to study because of its ephemeral and variable qualities. This review covers recent efforts to probe pmf in vivo as well as efforts to address one of the key questions in photosynthesis: How does the photosynthetic machinery achieve sufficient flexibility to meet the energetic and regulatory needs of the plant in a varying environment? It is concluded that pmf plays a central role in these flexibility mechanisms.
