Transcriptome dynamics in developing leaves from C3 and C4 Flaveria species

The Plant Journal, Volume 120, Issue 4, Page 1438-1456, November 2024.
SUMMARY C4 species have evolved more than 60 times independently from C3 ancestors. This multiple and parallel evolution of the complex C4 trait suggests common underlying evolutionary mechanisms, which could be identified by comparative analysis of closely related C3 and C4 species.

Chloroplast NADH dehydrogenase‐like complex‐mediated cyclic electron flow is the main electron transport route in C4 bundle sheath cells

New Phytologist, Volume 243, Issue 6, Page 2187-2200, September 2024.
Summary The superior productivity of C4 plants is achieved via a metabolic C4 cycle which acts as a CO2 pump across mesophyll and bundle sheath (BS) cells and requires an additional input of energy in the form of ATP. The importance of chloroplast NADH dehydrogenase‐like complex (NDH) operating cyclic electron flow (CEF) around Photosystem I (PSI) for ...

SlPGR5/SlPGRL1 pathway-dependent cyclic electron transport regulates photoprotection and chloroplast quality in tomato plants

Horticultural Plant Journal
The essential photoprotective role of proton gradient regulation 5 (PGR5)-dependent cyclic electron flow (CEF) has been reported in Arabidopsis, rice, and algae. However, its functional assessment has not been performed in tomato yet.

Strong heterologous electron sink outcompetes alternative electron transport pathways in photosynthesis

The Plant Journal, Volume 119, Issue 5, Page 2500-2513, September 2024.
SUMMARY Improvement of photosynthesis requires a thorough understanding of electron partitioning under both natural and strong electron sink conditions. We applied a wide array of state‐of‐the‐art biophysical and biochemical techniques to thoroughly investigate the fate of photosynthetic electrons in the engineered cyanobacterium Synechocystis sp.

The operation of PEPCK increases light harvesting plasticity in C4 NAD–ME and NADP–ME photosynthetic subtypes: A theoretical study

Plant, Cell &Environment, Volume 47, Issue 6, Page 2288-2309, June 2024.
Abstract The repeated emergence of NADP–malic enzyme (ME), NAD–ME and phosphoenolpyruvate carboxykinase (PEPCK) subtypes of C4 photosynthesis are iconic examples of convergent evolution, which suggests that these biochemistries do not randomly assemble, but are instead specific adaptations resulting from unknown evolutionary drivers.

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.

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 ...
