Oxidative Stress- and Autophagy-Inducing Effects of PSI-LHCI from Botryococcus braunii in Breast Cancer Cells

open access: yesBioTech, 2022
Botryococcus braunii (B. braunii) is a green microalga primarily found in freshwater, reservoirs, and ponds. Photosynthetic pigments from algae have shown many bioactive molecules with therapeutic potential.

Different adaptation strategies of two citrus scion/rootstock combinations in response to drought stress [PDF]

open access: yes, 2017
Scion/rootstock interaction is important for plant development and for breeding programs. In this context, polyploid rootstocks presented several advantages, mainly in relation to biotic and abiotic stresses.

Impaired photosystem I oxidation induces STN7-dependent phosphorylation of the light-harvesting complex I protein Lhca4 in Arabidopsis thaliana

open access: yesPlanta, 2007
Reduction of the plastoquinone (PQ) pool is known to activate phosphorylation of thylakoid proteins. In the Arabidopsis thaliana mutants psad1-1 and psae1-3, oxidation of photosystem I (PSI) is impaired, and the PQ pool is correspondingly over-reduced ...

Spectrally selective fluorescence imaging of Chlorobaculum tepidum reaction centers conjugated to chelator-modified silver nanowires [PDF]

open access: yes, 2017
A polyhistidine tag (His-tag) present on Chlorobaculum tepidum reaction centers (RCs) was used to immobilize photosynthetic complexes on a silver nanowire (AgNW) modified with nickel-chelating nitrilo-triacetic acid (Ni-NTA).

A novel chloroplast super-complex consisting of the ATP synthase and photosystem I reaction center.

open access: yesPLoS ONE, 2020
Several 'super-complexes' of individual hetero-oligomeric membrane protein complexes, whose function is to facilitate intra-membrane electron and proton transfer and harvesting of light energy, have been previously characterized in the mitochondrial ...

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

open access: yes, 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

Localization and Topology of Thylakoid Membrane Proteins in Land Plants

open access: yesBio-Protocol, 2014
Thylakoids are a formation of flattened membrane vesicles and protein complexes found in cyanobacteria, algae and plants. In the chloroplasts of land plants the thylakoid membrane systems form a network of densely packed stacks called grana lamellae ...
