Regulation of electron transport is essential for photosystem I stability and plant growth [PDF]

, 2020
Photosynthetic electron transport is regulated by cyclic and pseudocyclic electron flow (CEF and PCEF) to maintain the balance between light availability and metabolic demands. CEF transfers electrons from photosystem I to the plastoquinone pool with two

Dynamics and interplay of photosynthetic regulatory processes depend on the amplitudes of oscillating light

Plant, Cell &Environment, Volume 47, Issue 6, Page 2240-2257, June 2024.
Abstract Plants have evolved multiple regulatory mechanisms to cope with natural light fluctuations. The interplay between these mechanisms leads presumably to the resilience of plants in diverse light patterns. We investigated the energy‐dependent nonphotochemical quenching (qE) and cyclic electron transports (CET) in light that oscillated with a 60‐s

Alternative electron sinks in chloroplasts and mitochondria of halophytes as a safety valve for controlling ROS production during salinity

Physiologia Plantarum, Volume 176, Issue 3, May/June 2024.
Abstract Electron flow through the electron transport chain (ETC) is essential for oxidative phosphorylation in mitochondria and photosynthesis in chloroplasts. Electron fluxes depend on environmental parameters, e.g., ionic and osmotic conditions and endogenous factors, and this may cause severe imbalances.

Transcriptomic and proteomic analyses of distinct Arabidopsis organs reveal high PSI‐NDH complex accumulation in stems

Physiologia Plantarum, Volume 176, Issue 2, March/April 2024.
Abstract In addition to leaves, the main site of photosynthetic reactions, active photosynthesis also takes place in stems, siliques and tree trunks. Although non‐foliar photosynthesis has a marked effect on plant growth and yield, only limited information on the expression patterns of photosynthesis‐related genes and the structure of photosynthetic ...

Image_1_Inactivation of photosynthetic cyclic electron transports upregulates photorespiration for compensation of efficient photosynthesis in Arabidopsis.tif

, 2023
Plants have multiple mechanisms to maintain efficient photosynthesis. Photosynthetic cyclic electron transports around photosystem I (CET), which includes the PGR5/PGRL1 and NDH pathways, and photorespiration play a crucial role in photosynthetic ...

DataSheet_1_High light-induced changes in whole-cell proteomic profile and its correlation with the organization of thylakoid super-complex in cyclic electron transport mutants of Chlamydomonas reinhardtii.docx

, 2023
Light and nutrients are essential components of photosynthesis. Activating the signaling cascades is critical in starting adaptive processes in response to high light.

Ca2+-regulated cyclic electron flow supplies ATP for nitrogen starvation-induced lipid biosynthesis in green alga

, 2015
We previously showed that both the linear photosynthetic electron transportation rate and the respiration rate dropped significantly during N starvation-induced neutral lipid accumulation in an oil-producing microalga, Chlorella sorokiniana, and proposed

The proxiomes of CDJ5 and PGRL1 in Chlamydomonas reinhardtii overlap depending on the ability of CDJ5 to bind a 4Fe-4S cluster

The chloroplast chaperone HSP70B from Chlamydomonas reinhardtii works with the J-domain co-chaperones CDJ1 to CDJ6. CDJ1 delivers unfolded proteins, while CDJ2 delivers VIPP1 as substrate to HSP70B. CDJ3 to CDJ5 contain 4Fe-4S clusters in addition to the J domain, but their function is unknown.

Cyclic and pseudo-cyclic electron pathways play antagonistic roles during nitrogen deficiency in Chlamydomonas reinhardtii

International audienceNitrogen (N) scarcity frequently constrains global biomass productivity. N deficiency halts cell division, downregulates photosynthetic electron transfer (PET), and enhances carbon storage.
