Ascorbic Acid Alleviates Damage from Heat Stress in the Photosystem II of Tall Fescue in Both the Photochemical and Thermal Phases

Frontiers in Plant Science, 2017
L-Ascorbate (Asc) plays important roles in plant development, hormone signaling, the cell cycle and cellular redox system, etc. The higher content of Asc in plant chloroplasts indicates its important role in the photosystem.

Data assessing genotypic variations in selected traditional rice landraces of Jeypore tract of Odisha, India based on photosynthetic traits

Data in Brief, 2019
Variations in photosynthetic characteristics and dry matter accumulation were investigated in thirty selected rice (Oryza sativa L.) landraces from Jeypore tract of Odisha, India to find the possibility of their use in crop improvement programs. Leaf gas

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Drought and photosystem II activity in two Mediterranean oaks [PDF]

Annales des Sciences Forestières, 1996
La reponse du photosysteme Il (PS II) a la secheresse a ete analysee sur deux especes de chenes mediterraneens, Quercus ilex et Q pubescens par la technique de la fluorescence chlorophyllienne pulsee. L'efficacite photochimique maximale du PS II (F v /F m ) de Q ilex (sempervirent) et de Q pubescens (caducifolie) n'a ete affectee que pour un potentiel ...

Iron Deficiency Induces a Partial Inhibition of the Photosynthetic Electron Transport and a High Sensitivity to Light in the Diatom Phaeodactylum tricornutum

Frontiers in Plant Science, 2016
Iron limitation is the major factor controlling phytoplankton growth in vast regions of the contemporary oceans. In this study, a combination of thermoluminescence, chlorophyll fluorescence and P700 absorbance measurements have been used to elucidate the

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]

, 2017
Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

N-Methylanilinocyanoacrylate Photosystem II Inhibitors. Structure-Activity Relationships

Zeitschrift für Naturforschung C, 1993
Abstract Many 3-N-methylanilino cyanoacrylate derivatives are potent inhibitors of photosynthetic electron transport at the PS II level in a thylakoid system isolated from Pisum sativum. These inhibitors are somewhat unusual in that they take more than 15 min to equilibrate with the binding site in contrast to most classical PS II ...

Induction Kinetics of Photosystem I-Activated P700 Oxidation in Plant Leaves and Their Dependence on Pre-Energization [PDF]

, 2010
Absorbance changes ¿A 810 were measured in pea (Pisum sativum L., cv. Premium) leaves to track redox transients of chlorophyll P700 during and after irradiation with far red (FR) light under various preillumination conditions in the absence and presence ...

The effect of Cd2+ on the release of proteins from thylakoid membranes of tomato leaves

Acta Societatis Botanicorum Poloniae, 2014
The polypeptide pattern of the thylakoid membrane was investigated to elucidate the decrease of photosystem II (PSII) activity due to Cd2+ incubation. The release of polypeptides depended on the concentration of the metal and time of incubation.

Modification of photosystem II activity by protein phosphorylation

FEBS Letters, 1985
Phosphorylation of proteins within pea thylakoid membranes decreases photosystem II (PSII) mediated electron transfer at saturating light intensities which, according to changes in room temperature chlorophyll fluorescence transients, is due to a modification in the electron transfer from QAto QB.
