总结了生育酚在叶绿体抗氧化网络中的作用，特别是在强光下保护 PSII 方面的作用的最新进展。讨论了反应中心通过 P680 三线态形成产生单线态氧的来源和条件，以及生育酚对这种单线态氧的清除。这可能是植物在高光驯化中生育酚的必然功能。此外，生育酚是应激信号中 ROS 调节系统的一部分。
Recent developments on the role of tocopherol in the antioxidant network of the chloroplast and, in particular, in the protection of PSII in high light are summarized. The origin and conditions for singlet oxygen production in the reaction centre via P680 triplet formation are discussed, as well as the scavenging of this singlet oxygen by tocopherol. This is probably the obligatory function of tocopherol in the plant in high light acclimation. Furthermore, tocopherol is part of the modulation system of ROS in stress signalling.
