目前的假说的光系统II（PSII）在体内的光损伤的机制仍然分裂的主要损害网站。然而，大多数研究者认为，PSII是由一个单一的机制，光抑制PSII由一个人口。从这个角度出发，我们提出了“混合种群假说”，其中有四个PSII种群：PSII与活性/非活性Mn 4CaO 5放氧复合物分别与功能/受损的伯醌（Q（A））还原活性。这一假说提供了一个新的见解，不仅PSII光抑制/光保护的研究，但也修复过程。我们讨论了我们的新数据，这意味着修复率不同，在各自的PSII人口。
The current hypotheses for the mechanisms of photosystem II (PSII) photodamage in vivo remain split on the primary damage site. However, most researchers have considered that PSII is inhibited by a sole mechanism and that the photoinhibited PSII consists of one population. In this perspective, we propose 'the mixed population hypothesis', in which there are four PSII populations: PSII with active/inactive Mn4CaO5 oxygen-evolving complex respectively with functional/damaged primary quinone (Q(A)) reduction activity. This hypothesis provides a new insight into not only the PSII photoinhibition/photoprotection studies but also the repair process. We discuss our new data implying that the repair rate differs in the respective PSII populations.
