Thylakoid - Wikipedia
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum).
Thylakoid Membrane - an overview | ScienceDirect Topics
The thylakoid membrane is the site of light energy transduction, using electrons from water to reduce NADP + and produce O 2, and pump H + into the thylakoid lumen with ADP phosphorylation as the H + returns to the stroma (eukaryotes) or cytosol (cyanobacteria) (Nicholls and Ferguson, 2013; Sari et al., 2013; Mullineaux and Liu, 2020; Wilhelm ...
Probing the biogenesis pathway and dynamics of thylakoid membranes - Nature
2021年6月9日 · Here, we develop a method to modulate thylakoid biogenesis in the rod-shaped cyanobacterium Synechococcus elongatus PCC 7942 by modulating light intensity during cell growth, and probe the...
Granal thylakoid structure and function: explaining an enduring …
The chloroplast thylakoid is one of the most complex, highly organized biological membrane networks in nature. A striking feature of the thylakoid in higher plants is its bipartite architecture, which consists of appressed grana stacks and unstacked stroma lamellae.
A brief history of thylakoid biogenesis - PMC
The thylakoid membrane network inside chloroplasts harbours the protein complexes that are necessary for the light-dependent reactions of photosynthesis. Cellular processes for building and altering this membrane network are therefore essential for ...
Thylakoid Membrane - an overview | ScienceDirect Topics
The thylakoid membrane refers to the highly folded membranes found in chloroplasts, specifically in plants and green algae. These membranes contain stacked (grana) and unstacked (stromal) regions and enclose an inner aqueous compartment called the lumen.
Thylakoid Membrane - an overview | ScienceDirect Topics
Thylakoids represent remarkably conserved energy-transducing membranes with a high protein complexes/lipid ratio that can reach up to 80% in stacked grana regions of eukaryotic chloroplasts. The lipophilic matrix in which the protein/pigment complexes are embedded is unique, and has been conserved during the course of evolution.
3D Visualization of Thylakoid Membrane Development
2016年5月5日 · Every stage of thylakoid development is shown in a traditional TEM view, outlining the membranes to be visualized in 3D. Then, the 3D structures of the outlined areas are presented and rotated to show membrane surfaces from many angles during the membrane transformations.
Structure, Composition, Functional Organization and Dynamic …
All of the light-harvesting and energy-transducing functions are located in the thylakoids, which form a physically continuous membrane system that encloses an aqueous compartment, the thylakoid lumen. With few exceptions thylakoids are differentiated into stacked grana and non-stacked stroma membrane regions.
The structural and functional domains of plant thylakoid membranes
2018年10月12日 · In plants, the stacking of part of the photosynthetic thylakoid membrane generates two main subcompartments: the stacked grana core and unstacked stroma lamellae. However, a third distinct domain, the grana margin, has been postulated but its structural and functional identity remains elusive.
