【Abstract】 The PSⅡ super complex consists of a reaction center and a peripheral light-harvesting pigment complex. The assembly process includes the formation of a PSⅡ reaction center, the assembly of the primary PSⅡ complex, and the assembly of the light-harvesting pigment complex. In the assembly process of the PSⅡ super complex, various protein factors represented by the TPR family and the HCF family are involved in assembly as an assembly cofactor. Photoinhibition was historically described as an imbalance between PSⅡ photodamage and its subsequent repair, rapid protein degradation and replacement is an important response to photodamage and a means of photoprotection. The repair cycle system of PSⅡ rapidly degrade the damaged D1 protein and other components, and re-synthesize the PSⅡ super complex, which will restore photosynthesis from the rapid restoration of photosynthetic systems in plants.更多还原
