Thylakoids reorganization enables driving photosynthesis under far‐red light in the microalga Nannochloropsis gaditana

New Phytologist, Volume 249, Issue 4, Page 1785-1799, February 2026.
Summary Oxygenic photosynthesis is driven by visible light in most photosynthetic organisms, with exceptions in a few cyanobacteria and microalgae species, which can extend the light absorption to far‐red (FR) wavelengths, by synthesizing new pigments or shifting the antennae absorption range beyond 700 nm.

Moderate photoinhibition of photosystem II protects photosystem I from photodamage at chilling stress in tobacco leaves

Frontiers in Plant Science, 2016
It has been indicated that photosystem I (PSI) is susceptible to chilling-light stress in tobacco leaves, but the effect of growth light intensity on chilling-induced PSI photoinhibition in tobacco is unclear.

Photorespiration Coupled With CO2 Assimilation Protects Photosystem I From Photoinhibition Under Moderate Poly(Ethylene Glycol)-Induced Osmotic Stress in Rice

Frontiers in Plant Science, 2020
Photorespiration coupled with CO2 assimilation is thought to act as a defense system against photoinhibition caused by osmotic stress. In the present study, we examined whether such a mechanism is operative for the protection of photosystem I (PSI) in ...

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, Volume 600, Issue 2, Page 164-187, January 2026.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Responses of the Photosynthetic Electron Transport Reactions Stimulate the Oxidation of the Reaction Center Chlorophyll of Photosystem I, P700, under Drought and High Temperatures in Rice [PDF]

International Journal of Molecular Sciences, 2019
It is of interest how photosynthetic electron transport (PET) reactions respond to excess light energy caused by the combination of drought stress and high temperatures. Since such information is scarcely available for photosystem I (PSI), this question was explored in rice (Oryza sativa L.) plants subjected to drought stress, using culture solutions ...

Variation potential influence on photosynthetic cyclic electron flow in pea

Frontiers in Plant Science, 2015
Cyclic electron flow is an important component of the total photosynthetic electron flow and participates in adaptation to the action of stressors. Local leaf stimulation induces electrical signals, including variation potential (VP), which inactivate ...

Differences in photosystem II activity and carbon allocation during photomixotrophic growth in distinct wild‐type strains of Synechocystis sp. PCC 6803

The Plant Journal, Volume 125, Issue 2, January 2026.
SUMMARY The regulation of photosynthetic electron transport during photomixotrophic growth in cyanobacteria remains incompletely understood. In this study, we characterized four wild‐type strains (WT 1–4) of Synechocystis sp. PCC 6803 and observed distinct strain‐specific differences in photosystem II (PSII) function under photomixotrophic conditions ...

Iron physiology and metabolism of model phytoplankton taxa in a western boundary continental shelf ecosystem

Limnology and Oceanography, Volume 70, Issue 11, Page 3335-3354, November 2025.
Abstract Continental shelf ecosystems support diverse phytoplankton communities that contribute to global primary productivity. Iron is an important micronutrient controlling the growth of marine phytoplankton, but its role in influencing phytoplankton ecophysiology in western boundary continental shelf ecosystems is understudied.

Role of Plastocyanin in response to photosynthetic electron transport in Solanum nigrum under Cd stress

Plant Stress
Plastocyanin (PC), an essential electron carrier located between the cytochrome b6f (cytb6f) complex and PSI in photosynthetic electron transport, remains inadequately understood regarding its regulatory role in electron transfer under heavy metal stress.

Identifying overtraining biomarkers through proteomic analysis of extracellular vesicles derived from the central nervous system of male mice

Physiological Reports, Volume 13, Issue 21, November 2025.
Abstract Overtraining, which results in central nervous system (CNS)‐fatigue‐related symptoms, leads to a long‐term decline in performance. This study investigated CNS‐derived EV protein content under overtraining conditions to identify potential biomarkers.
