The formation of homogentisate in the biosynthesis of tocopherol and plastoquinone in spinach chloroplasts [PDF]

open access: yes, 1982
Homogentisate is the precursor in the biosynthesis of -tocopherol and plastoquinone-9 in chloroplasts. It is formed of 4-hydroxyphenylpyruvate of the shikimate pathway by the 4-hydroxyphenylpyruvate dioxygenase.

Response of Vicia faba L. to metal toxicity on mine tailing substrate:Geochemical and morphological changes in leaf and root [PDF]

open access: yes, 2009
Vicia faba L. seeds were grown in a pot experiment on soil, mine tailings, and a mixture of both to mimic field situations in cultivated contaminated areas near mining sites. Metals in the substrates and their translocation in root, stem and leaf tissues

Effects of Storage Conditions on Degradation of Chlorophyll and Emulsifying Capacity of Thylakoid Powders Produced by Different Drying Methods

open access: yesFoods, 2020
Thylakoid membranes isolated from spinach have previously been shown to inhibit lipase/co-lipase and prolong satiety in vivo. There is a need to develop thylakoid products that not only have the desired characteristics and functionality after processing,

The lifetime of the oxygen‐evolving complex subunit PSBO depends on light intensity and carbon availability in Chlamydomonas

open access: yesPlant, Cell &Environment, Volume 46, Issue 2, Page 422-439, February 2023., 2023
Abstract PSBO is essential for the assembly of the oxygen‐evolving complex in plants and green algae. Despite its importance, we lack essential information on its lifetime and how it depends on the environmental conditions. We have generated nitrate‐inducible PSBO amiRNA lines in the green alga Chlamydomonas reinhardtii.

The Kinase STATE TRANSITION 8 Phosphorylates Light Harvesting Complex II and Contributes to Light Acclimation in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2019
Phosphorylation of the light-harvesting complex II (LHCII) is a central trigger for the reorganization of the photosynthetic complexes in the thylakoid membrane during short-term light acclimation.

Energy storage in the photosynthetic electron-transport chain: An analogy with Michaelis-Menten kinetics [PDF]

open access: yesJournal of the Serbian Chemical Society, 2003
Simultaneous measurements of fluorescence and thermal emission have been performed by applying combined fluorescence and photoacoustic techniques on isolated thylakoids pretreated by prolonged illumination with saturating light.

Lattice models for protein organization throughout thylakoid membrane stacks [PDF]

open access: yes, 2019
Proteins in photosynthetic membranes can organize into patterned arrays that span the membrane's lateral size. Attractions between proteins in different layers of a membrane stack can play a key role in this ordering, as was suggested by microscopy and fluorescence spectroscopy and demonstrated by computer simulations of a coarse-grained model.

Thylakoid membrane function in heterocysts

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2016
Multicellular cyanobacteria form different cell types in response to environmental stimuli. Under nitrogen limiting conditions a fraction of the vegetative cells in the filament differentiate into heterocysts. Heterocysts are specialized in atmospheric nitrogen fixation and differentiation involves drastic morphological changes on the cellular level ...

A guanosine 5′-triphosphate-dependent protein kinase is localized in the outer envelope membrane of pea chloroplasts [PDF]

open access: yes, 1988
A guanosine 5-triphosphate (GTP)-dependent protein kinase was detected in preparations of outer chloroplast envelope membranes of pea (Pisum sativum L.) chloroplasts.

Correlation between Chloroplast Ultrastructure and Chlorophyll Fluorescence Characteristics in the Leaves of Rice (Oryza sativa L.) Grown under Salinity

open access: yesPlant Production Science, 2008
The seedlings of Oryza sativa L. cv. Nipponbare grown by hydroponic culture for 3 wks were treated with 75, 100, 150 and 200 mM NaCl for 14, 14, 6 and 3 days, respectively, and examined for chloroplast ultrastructure in the region where chlorophyll ...
