Parameterization of photoinhibition for phytoplankton

Communications Earth & Environment
Mathematical models of photosynthesis–irradiance relationships in phytoplankton are used to compute integrated water-column photosynthetic rates and predict primary production. Models typically ignore an important phenomenon observed in most experiments:

Photoinhibition and protection of photosystem I. [PDF]

Plant Cell Physiol, 2007
Abstract Over 30 years ago, when we first reported the selective photoinhibition of photosystem I (PSI) in chilling-sensitive plants at chilling temperatures, the inhibition tended to be regarded as a specific phenomenon observed only under unusual conditions.

Photoinhibition of FeFe Hydrogenase [PDF]

ACS Catalysis, 2017
In the enzyme FeFe hydrogenase, hydrogen oxidation and production occur at the H-cluster, a Fe6S6 active site that bears intrinsic carbonyl and cyanide ligands. This enzyme has been coupled to photosensitizers to design H2 photoproduction systems, and yet, according to earlier reports, the enzyme from Desulfovibrio desulfuricans is "easily destroyed ...

Enhanced function of non-photoinhibited photosystem II complexes upon PSII photoinhibition

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2023
Light induced photosystem (PS)II photoinhibition inactivates and irreversibly damages the reaction center protein(s) but the light harvesting complexes continue the collection of light energy. Here we addressed the consequences of such a situation on thylakoid light harvesting and electron transfer reactions.

Photosynthesis in the Biomass Model Species Lemna minor Displays Plant-Conserved and Species-Specific Features

Plants, 2023
Lemnaceae are small freshwater plants with extraordinary high growth rates. We aimed to test whether this correlates with a more efficient photosynthesis, the primary energy source for growth.

STED-Inspired Cationic Photoinhibition Lithography

The Journal of Physical Chemistry C, 2023
Direct laser writing by two-photon lithography has been enhanced substantially during the past two decades by techniques borrowed from stimulated emission depletion (STED) microscopy. However, STED-inspired lithography was so far limited to radical polymerizations, mostly to acrylates and methacrylates.

Growth Light Environment Changes the Sensitivity of Photosystem I Photoinhibition Depending on Common Wheat Cultivars

Frontiers in Plant Science, 2019
Light is an important factor for determining photosynthetic performance in land plants. At high light intensity, land plants develop photosynthetic activity by increasing electron sinks, such as the Calvin cycle and photorespiration and photoprotective ...

The moss Bryum argenteum var. muticum Brid. is well adapted to cope with high light in continental Antarctica [PDF]

, 2012
The net photosynthetic rate (NP), chlorophyll fluorescence, carotenoid content and chlorophyll content of the cosmopolitan moss Bryum argenteum were measured in the field at Botany Bay, southern Victoria Land, continental Antarctica (77°S).
