Protein phosphorylation landscape in photosystem I of the desert algae Chlorella sp

ABSTRACT: The regulation of photosynthesis in response to varying light conditions is primarily controlled through the phosphorylation of thylakoid proteins. This process is most extensively studied in the context of the phosphorylation of photosystem II (PSII) and light-harvesting complex II (LHCII) subunits. However, there is comparatively less understanding of the changes induced by light stress in photosystem I and light-harvesting complex I (LHCI). In this study, we examined the alterations in protein phosphorylation of PSI-LHCI in Chlorella ohadii, an extremely light-tolerant desert green alga, when grown under low light (LL) and high light (HL) conditions.

The phosphorylation of photosystem II (PSII) and its antenna (LHCII) proteins has been studied, and its involvement in state transitions and PSII repair is known. Yet, little is known about the phosphorylation of photosystem I (PSI) and its antenna (LHCI) proteins. Here, we applied proteomics analysis to generate a map of the phosphorylation sites of the PSI-LHCI proteins in Chlorella ohadii cells that were grown under low or extreme high-light intensities (LL and HL). Furthermore, we analyzed t  ...[more]
