Life, 2014 Cyanobacteria use large pigment-protein complexes called phycobilisomes to harvest light energy primarily for photosystem II (PSII). We used a series of mutants with partial to complete reduction of phycobilisomes to examine the effects of antenna ...

Quality Control of Photosystem II [PDF]
Plant and Cell Physiology, 2001 Photosystem II is particularly vulnerable to excess light. When illuminated with strong visible light, the reaction center D1 protein is damaged by reactive oxygen molecules or by endogenous cationic radicals generated by photochemical reactions, which is followed by proteolytic degradation of the damaged D1 protein.

Food Safety and Health, EarlyView.Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Frontiers in Plant Science, 2016 The photosystem II (PSII) activity of C3 plants is usually inhibited at noon associated with high light but can be repaired fast in the afternoon. However, the diurnal variation of photosystem I (PSI) activity is unknown.

Journal of the Chinese Chemical Society, EarlyView.While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Frontiers in PhotobiologyIn this review, we consider the effects of trehalose on charge transfer processes in three distinct photosynthetic systems under different conditions, namely: (i) the effect of relative hydration of the trehalose glassy matrix on forward and backward ...

Journal of the Chinese Chemical Society, EarlyView.A trinuclear manganese complex supported by the 7‐Dipy scaffold undergoes controlled multielectron oxidation from Mn(II)3 to high‐valent Mn(IV)3 states. Spectroscopic signatures, including 16‐line and geff ≈ 5 EPR features, reveal stepwise redox accumulation. The oxidized Mn3 cluster mediates efficient oxygen‐atom transfer to strong CH bonds, enabling

EPJ Web of Conferences, 2015 This short review summarizes our current knowledge about the functional relevance of protein dynamics in photosynthetic reaction centers. In the case of Photosystem II membrane fragments, elastic and quasielastic neutron scattering experiments reveal a ...

Applications of Delayed Fluorescence from Photosystem II
Sensors, 2013 While photosystem II (PSII) of plants utilizes light for photosynthesis, part of the absorbed energy may be reverted back and dissipated as long-term fluorescence (delayed fluorescence or DF). Because the generation of DF is coupled with the processes of

Journal of Plant Nutrition and Soil Science, EarlyView.Wheat wild relatives are untapped genetic resources from salinity and drought hit areas. This study presents differential comparative morphophysiological responses of these species and modern wheat cultivars under saline conditions. Salt resistant species produce more shoot and root biomass under saline conditions through salt exclusion and/or tissue ...
