The regulation of photosynthesis occurs at different levels including the control of nuclear and plastid genes transcription, RNA processing and translation, protein translocation, assemblies and their post translational modifications. Out of all these, post translational modification enables rapid response of plants towards changing environmental conditions. Among all post-translational modifications, reversible phosphorylation is known to play a crucial role in the regulation of light reaction of photosynthesis. Although, phosphorylation of PS II subunits has been extensively studied but not much attention is given to other photosynthetic complexes such as PS I, Cytochrome b6f complex and ATP synthase. Phosphorylation reaction is known to protect photosynthetic apparatus in challenging environment conditions such as high light, elevated temperature, high salinity and drought. Recent studies have explored the role of photosynthetic protein phosphorylation in conferring plant immunity against the rice blast disease. The evolution of phosphorylation of different subunits of photosynthetic proteins occurred along with the evolution of plant lineage for their better adaptation to the changing environment conditions. In this review, we summarize the progress made in the research field of phosphorylation of photosynthetic proteins and highlights the missing links that need immediate attention.
光合作用的调节发生在不同的水平，包括核和质体基因转录、RNA 加工和翻译、蛋白质易位、组装及其翻译后修饰的控制。在所有这些中，翻译后修饰使植物能够快速应对不断变化的环境条件。在所有翻译后修饰中，可逆磷酸化被认为在光合作用光反应的调节中起着关键作用。虽然 PS II 亚基的磷酸化已被广泛研究，但对其他光合复合物如 PS I、细胞色素 b6f 复合物和 ATP 合酶的关注较少。磷酸化反应已知可在具有挑战性的环境条件下保护光合器官，如高光、高温、高盐和干旱。最近的研究探讨了光合作用蛋白磷酸化在赋予植物对稻瘟病免疫中的作用。不同光合蛋白亚基磷酸化的进化伴随着植物谱系的进化而发生，以更好地适应不断变化的环境条件。在这篇综述中，我们总结了光合作用蛋白磷酸化研究领域的进展，并强调了需要立即关注的缺失环节。
