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

open access: yes, 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 ...

A Cross‐Climate Comparison of Molecular Phenology in Three Tropical and Temperate Trees

open access: yesPlant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT Latitudinal gradients in temperature seasonality shape the evolution of thermal tolerance and acclimation capacity in organisms. According to Janzen's climate variability hypothesis, tropical species experiencing stable temperatures evolve narrower thermal niches than temperate counterparts.

PPSR1 Protein Functions as an Important Regulator to Enhance Plant Growth Performance Under N, P, and K Deficient Stress Conditions

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2385-2404, April 2026.
ABSTRACT Phosphorus (P) is an essential macronutrient for various biological processes in plant growth. Modern agricultural science has advanced the knowledge of regulatory mechanisms underlying phosphorus starvation responses (PSRs), aiming to develop phosphate‐efficient crops with sustainable production under reduced Pi fertilizer application ...

Coordinated Activity of Photosystem I and Photosystem II in Selaginella martensii (Lycopodiophyta) Across Light Gradients

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Selaginella martensii is a living member of lycophytes, an early divergent group of vascular plants. This shade‐adapted species can acclimate to various light regimes, from deep shade to high light, with a gain in carboxylation capacity accompanied by modulations in thylakoid composition, including increased relative amount of photosystem I ...

Regulation mechanism of melatonin on photosynthesis of cucumber under high temperature stress

open access: yesVegetable Research
Melatonin (MT) is an important regulator that participates in plant growth and stress tolerance. The aim of this study was to determine how MT alleviates the decline of photosynthesis in cucumber seedlings under high-temperature stress.

Changing frequency of fluctuating light reveals the molecular mechanism for P700 oxidation in plant leaves

open access: yesPlant Direct, 2018
Natural sunlight exceeds the demand of photosynthesis such that it can cause plants to produce reactive oxygen species (ROS), which subsequently cause photo‐oxidative damage.

Bundle sheath cell‐specific expression of chloroplast genes encoding subunits of the NADH dehydrogenase‐like complex in maize

open access: yesThe Plant Journal, Volume 124, Issue 5, December 2025.
SUMMARY C4 photosynthesis alleviates the limitation caused by the oxygenase activity of Rubisco by partitioning photosynthetic functions between two distinct cell types: bundle sheath cells (BSCs) and mesophyll cells (MCs). These cell types perform different steps of photosynthesis using specialized machinery, accompanied by differential expression of ...

Glucose Uncouples Nitrogen Sensing From Chlorosis via a Photosynthetic Checkpoint in Synechocystis sp. PCC 6803

open access: yesPhysiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Cyanobacteria adapt to nitrogen starvation by undergoing chlorosis, a regulated bleaching process that involves the degradation of phycobilisomes, the light‐harvesting antennae complexes, and accumulation of glycogen. While this response is well characterized under photoautotrophic conditions, its modulation by external organic carbon sources ...

PGR5 and NDH Pathways in Photosynthetic Cyclic Electron Transfer Respond Differently to Sublethal Treatment with Photosystem-Interfering Herbicides

open access: yes, 2016
Effects of sublethal levels of the photosystem-interfering herbicides atrazine (Atr) and methyl viologen (MV) on photosynthetic electron transport were investigated in Arabidopsis thaliana mutants with defects in cyclic electron transfer (CET) activity ...
