Parameterization of photoinhibition for phytoplankton

open access: yesCommunications 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]

open access: yesPlant 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]

open access: yesACS 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 ...

The cost of photoinhibition [PDF]

open access: yesPhysiologia Plantarum, 2011
Photoinhibition is an inevitable consequence of oxygenic photosynthesis. However, the concept of a ‘photoinhibition‐proof’ plant in which photosystem II (PSII) is immune to photodamage is useful as a benchmark for considering the performances of plants with varying mixes of mechanisms which limit the extent of photodamage and which repair photodamage ...

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

open access: yesFrontiers 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 ...

Photosynthetic responses of Eulophia dentata, Bletilla formosana, and Saccharum spontaneum under various photosynthetic photon flux density conditions

open access: yesPhotosynthetica, 2022
This study aimed to determine the photosynthetic performance and differences in chlorophyll fluorescence (ChlF) parameters between Eulophia dentata and its companion species Bletilla formosana and Saccharum spontaneum when subjected to different ...

Contrasting photosynthesis and photoinhibition in tetraploid and its autodiploid honeysuckle (Lonicera japonica Thunb.) under salt stress

open access: yesFrontiers in Plant Science, 2015
Honeysuckle (Lonicera japonica Thunb.) is a popular landscape plant. This study was to explore leaf photosynthetic characterization with emphasis on the coordination between photosystem II (PSII) and photosystem I (PSI) in tetraploid and its autodiploid ...

A tomato chloroplast-targeted DnaJ protein, SlDnaJ20 maintains the stability of photosystem I/II under chilling stress

open access: yesPlant Signaling & Behavior, 2022
DnaJ proteins are key molecular chaperones that act as a part of the stress response to stabilize plant proteins, thereby maintaining protein homeostasis under stressful conditions.

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

open access: yesBiochimica 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.
