Physiological, Biochemical and Molecular Assessment of UV-A and UV-B Supplementation in Solanum lycopersicum

open access: yesPlants, 2021
Daily UV-supplementation during the plant fruiting stage of tomato (Solanum lycopersicum L.) growing indoors may produce fruits with higher nutraceutical value and better acceptance by consumers.

High light-induced changes in whole-cell proteomic profile and its correlation with the organization of thylakoid super-complex in cyclic electron transport mutants of Chlamydomonas reinhardtii

open access: yesFrontiers in Plant Science, 2023
Light and nutrients are essential components of photosynthesis. Activating the signaling cascades is critical in starting adaptive processes in response to high light.

Origin and evolution of water oxidation before the last common ancestor of the Cyanobacteria [PDF]

open access: yes, 2015
Photosystem II, the water oxidizing enzyme, altered the course of evolution by filling the atmosphere with oxygen. Here, we reconstruct the origin and evolution of water oxidation at an unprecedented level of detail by studying the phylogeny of all D1 ...

In Silico Analysis of Relationship between Proteins from Plastid Genome of Red Alga Palmaria sp. (Japan) and Angiotensin I Converting Enzyme Inhibitory Peptides

open access: yesMarine Drugs, 2019
Plastid proteins are one of the main components in red algae. In order to clarify the angiotensin I converting enzyme (ACE) inhibitory peptides from red alga Palmaria sp. (Japan), we determined the plastid genome sequence.

The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]

open access: yes, 2013
Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

Surface-Enhanced Resonance Raman Scattering Spectroscopy of Photosystem II Pigment-Protein Complexes

open access: yesThe Journal of Physical Chemistry, 1994
Three different photosystem II (PSII) pigment-protein complexes (D1-D2-Cyt b559-CP47, D1-D2-Cyt b559, and CP47) isolated from spinach were studied by surface-enhanced resonance Raman scattering (SERRS) spectroscopy. Surface-enhanced Raman scattering (SERS) is a distance sensitive (on a 5-10-Å scale) spectroscopic tool that can be used to examine ...

Plants lacking the main light-harvesting complex retain photosystem II macro-organization [PDF]

open access: yes, 2003
Photosystem II (PSII) is a key component of photosynthesis, the process of converting sunlight into the chemical energy of life. In plant cells, it forms a unique oligomeric macrostructure in membranes of the chloroplasts.
