The review is focused on analysis of the mechanisms of temperature-dependent regulation of electron transport and ATP synthesis in chloroplasts of higher plants. Importance of photosynthesis thermoregulation is determined by the fact that plants are ectothermic organisms, whose own temperature depends on the ambient temperature. The review discusses the effects of temperature on the following processes in thylakoid membranes: (i) photosystem 2 activity and plastoquinone reduction; (ii) electron transfer from plastoquinol (via the cytochrome bf complex and plastocyanin) to photosystem 1; (iii) transmembrane proton transfer; and (iv) ATP synthesis. The data on the relationship between the functional properties of chloroplasts (photosynthetic transfer of electrons and protons, functioning of ATP synthase) and structural characteristics of membrane lipids (fluidity) obtained by electron paramagnetic resonance studies are presented.
该综述重点分析了高等植物叶绿体中电子传递和 ATP 合成对温度依赖的调节机制。光合作用的温度调节之所以重要，是因为植物是变温动物，其自身的温度取决于环境温度。该综述讨论了温度对以下类囊体膜过程的影响：（i）光系统 2 活性和质体醌还原；（ii）电子从质体醇（通过细胞色素 bf 复合物和质体蓝素）转移到光系统 1；（iii）跨膜质子转移；和（iv）ATP 合成。通过电子顺磁共振研究获得的关于叶绿体功能特性（光合作用电子和质子转移、ATP 合酶的功能）与膜脂结构特性（流动性）之间关系的数据也在本文中呈现。
