Fractionation of Thylakoid Membranes Into Grana and Stroma Thylakoids
2004The chloroplasts contain an extensive system of internal membranes or thylakoids in which all the light-harvesting and energy-transducing processes of the photosynthesis are located. Thylakoids are differentiated into stacked membrane regions (or grana thylakoids) and nonstacked membranes (or stroma thylakoids), each with a specialized structure and ...

High sensitivity differential scanning calorimetry (DSC) was employed to study the thermal denaturation of components of pea chloroplast thylakoid membranes. In contrast to previous reports utilizing spinach thylakoids, several transitions are reversible, and deconvolution of the calorimetric curves indicates nine transitions in both first and second ...

Patterns of thylakoid system formation
Journal of Ultrastructure Research, 1979Plastid differentiation has been studied in leaves of both tobacco and wheat. We could point out a correlation between the differentiation speed of the plastids and that of the cell containing them. The ontogenetic patterns of both tobacco and wheat plastids appear to be different from the standard ones. The significance of these particular ontogeneses

Polylysine effect on thylakoid membranes
Biophysical Chemistry, 2020Thylakoid membranes of photosynthetic plant chloroplasts are involved in a wide range of energy producing pathways. Their stacking can be employed in order to provide increased surface area for biocatalytic purposes. Here we probe the aggregate formation of higher plants' thylakoids using low-molecular poly-l-lysine as an electrostatic polymer linker ...

Thylakoid membranes: The translational site of chloroplast DNA-regulated thylakoid polypeptides
Archives of Biochemistry and Biophysics, 1984Stromal ribosomes and those bound to thylakoid membranes were prepared from intact spinach chloroplasts which were purified on Percoll gradients. The products of read-out translation of these ribosomes supplemented with an Escherichia coli extract were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

Trends in Cell Biology, 1999
A dynamic synergy currently holds sway in the study of protein export across the bacterial inner membrane and chloroplast thylakoids. Initially, ideas flowed from the eubacterial to the thylakoid field, with chloroplast workers confirming the presence of Sec, signal-recognition particle (SRP) and spontaneous pathways in their system.

Proteomics seeks to monitor the global complement of proteins within a cell or organism and accompanying plasticity with respect to development and environment. The proteome is dynamic, the product of current and past gene expression, countless protein-protein interactions and selective proteolytic systems.

Redox regulation in the thylakoid lumen
Journal of Plant Physiology, 2016Higher plants need to balance the efficiency of light energy absorption and dissipative photo-protection when exposed to fluctuations in light quantity and quality. This aim is partially realized through redox regulation within the chloroplast, which occurs in all chloroplast compartments except the envelope intermembrane space.

Photoelectrochemistry of thylakoid membranes
Bioelectrochemistry and Bioenergetics, 1997Abstract A one-compartment three-electrode photoelectrochemical cell, first designed by Allen and Crane and recently modified by Carpentier, was used to study the chronoamperometric behavior of a suspension of thylakoids under saturating light conditions. The experimental results were modeled successfully by considering the processes occurring in the

Thylakoid membrane architecture
Functional Plant Biology, 1999Confocal scanning laser microscopic observations were made on live chloroplasts in intact cells and on mechanically isolated, intact chloroplasts. Chlorophyll fluorescence was imaged to observe thylakoid membrane architecture. C3 plant species studied included Spinacia oleracea L., Spathiphyllum sp. Schott, cv. ‘Mauna Loa’, and Pisum sativum L.
