High-resolution dissection of photosystem II electron transport reveals differential response to water deficit and heat stress in isolation and combination in pearl millet [Pennisetum glaucum (L.) R. Br.]

Frontiers in Plant Science, 2022
Heat and Water Deficit Stress (WDS) tend to impede and restrict the efficiency of photosynthesis, chlorophyll fluorescence, and maximum photochemical quantum yield in plants based on their characteristic ability to interfere with the electron transport ...

Rhodoquinone and Complex II of the Electron Transport Chain in Anaerobically Functioning Eukaryotes [PDF]

Journal of Biological Chemistry, 1995
Many anaerobically functioning eukaryotes have an anaerobic energy metabolism in which fumarate is reduced to succinate. This reduction of fumarate is the opposite reaction to succinate oxidation catalyzed by succinate-ubiquinone oxidoreductase, complex II of the aerobic respiratory chain.

24-epibrassinolide improved chilled tomato photosynthetic performance by stabilizing electron transport chain and function of photosystem II

Biologia Plantarum, 2022
To explore the protective mechanisms of brassinosteroids in the chill-induced photoinhibition in tomato (Solanum lycopersicum), we studied the effect of foliar sprayed 24-epibrassinolide (EBR, 0.1µM) on the gas exchange, chlorophyll fluorescence ...

Conducting chiral nickel( ii ) bis(dithiolene) complexes: structural and electron transport modulation with the charge and the number of stereogenic centres [PDF]

Journal of Materials Chemistry C, 2021
Chiral nickel( ii ) bis(dithiolene) complexes based on the mono- and bis-methylated ligands me-dddt and dm-dddt are Mott insulators or band gap semiconductors, with their conductivity modulated by the counter-ion and the number of stereogenic centres.

ETMB-RBF: discrimination of metal-binding sites in electron transporters based on RBF networks with PSSM profiles and significant amino acid pairs. [PDF]

PLoS ONE, 2013
BACKGROUND: Cellular respiration is the process by which cells obtain energy from glucose and is a very important biological process in living cell. As cells do cellular respiration, they need a pathway to store and transport electrons, the electron ...

Erratum to: Connectivity between electron transport complexes and modulation of photosystem II activity in chloroplasts [PDF]

Photosynthesis Research, 2017
In chloroplasts, photosynthetic electron transport complexes interact with each other via the mobile electron carriers (plastoquinone and plastocyanin) which are in surplus amounts with respect to photosystem I and photosystem II (PSI and PSII), and the cytochrome b 6 f complex.

Unveiling a key role of oxaloacetate-glutamate interaction in regulation of respiration and ROS generation in nonsynaptic brain mitochondria using a kinetic model.

PLoS ONE, 2021
Glutamate plays diverse roles in neuronal cells, affecting cell energetics and reactive oxygen species (ROS) generation. These roles are especially vital for neuronal cells, which deal with high amounts of glutamate as a neurotransmitter.

Chromophore-Assisted Light Inactivation of Mitochondrial Electron Transport Chain Complex II in Caenorhabditis elegans [PDF]

Scientific Reports, 2016
AbstractMitochondria play critical roles in meeting cellular energy demand, in cell death, and in reactive oxygen species (ROS) and stress signaling. Most Caenorhabditis elegans loss-of-function (lf) mutants in nuclear-encoded components of the respiratory chain are non-viable, emphasizing the importance of respiratory function.

The Physiological Functionality of PGR5/PGRL1-Dependent Cyclic Electron Transport in Sustaining Photosynthesis

Frontiers in Plant Science, 2021
The cyclic electron transport (CET), after the linear electron transport (LET), is another important electron transport pathway during the light reactions of photosynthesis.
