Heterocyst Thylakoid Bioenergetics [PDF]

Life, 2019
Heterocysts are specialized cells that differentiate in the filaments of heterocystous cyanobacteria. Their role is to maintain a microoxic environment for the nitrogenase enzyme during diazotrophic growth.

Thylakoid Protein Phosphorylation in Chloroplasts

Plant and Cell Physiology, 2021
Abstract Because of their abundance and extensive phosphorylation, numerous thylakoid proteins stand out amongst the phosphoproteins of plants and algae. In particular, subunits of light-harvesting complex II (LHCII) and of photosystem II (PSII) are dynamically phosphorylated and dephosphorylated in response to light conditions and ...

Thylakoids reorganization enables driving photosynthesis under far-red light in the microalga Nannochloropsis gaditana. [PDF]

New Phytol
Summary Oxygenic photosynthesis is driven by visible light in most photosynthetic organisms, with exceptions in a few cyanobacteria and microalgae species, which can extend the light absorption to far‐red (FR) wavelengths, by synthesizing new pigments or shifting the antennae absorption range beyond 700 nm.

Native architecture of the Chlamydomonas chloroplast revealed by in situ cryo-electron tomography

eLife, 2015
Chloroplast function is orchestrated by the organelle's intricate architecture. By combining cryo-focused ion beam milling of vitreous Chlamydomonas cells with cryo-electron tomography, we acquired three-dimensional structures of the chloroplast in its ...

Light induced changes in protein expression and uniform regulation of transcription in the thylakoid lumen of Arabidopsis thaliana. [PDF]

PLoS ONE, 2009
In plants oxygenic photosynthesis is performed by large protein complexes found in the thylakoid membranes of chloroplasts. The soluble thylakoid lumen space is a narrow and compressed region within the thylakoid membrane which contains 80-200 proteins ...

FZL, a dynamin-like protein localized to curved grana edges, is required for efficient photosynthetic electron transfer in Arabidopsis

Frontiers in Plant Science, 2023
Photosynthetic electron transfer and its regulation processes take place on thylakoid membranes, and the thylakoid of vascular plants exhibits particularly intricate structure consisting of stacked grana and flat stroma lamellae. It is known that several

The impact of physiologically relevant temperatures on physical properties of thylakoid membranes: a molecular dynamics study

Photosynthetica, 2023
Thylakoid membranes are energy-converting membranes with a unique lipid composition. Though the membranes are primarily composed of proteins, their photosynthetic function is strongly influenced by the lipid constituents.

Evolutionary Patterns of Thylakoid Architecture in Cyanobacteria

Frontiers in Microbiology, 2019
While photosynthetic processes have become increasingly understood in cyanobacterial model strains, differences in the spatial distribution of thylakoid membranes among various lineages have been largely unexplored.
