Research progress on the function of the thylakoid lumen proteins in chloroplasts
[Objective]Thylakoids are the important sites where photosynthesis takes place.The thylakoid membrane envelops form a central aqueous region known as the thylakoid lumen.There are various types of proteins residing in thylakoid lumen,including high chlorophyll fluorescence(HCF)proteins,immu-nophilins,oxygen-evolving complex(OEC)proteins,and PsbP-like proteins,etc.These proteins are con-sidered to play important roles during various physiological processes,such as photosynthesis,nucleotide metabolism,and redox regulation.[Reviews]This review summarized the function of the thylakoid lumen proteins involved in photosynthesis regulation,such as photosystem assembly,growth regulation,and ex-cess light stress response.[Prospect]The review provided the theoretical reference for future study on the physiological function of the thylakoid lumen proteins.
