Dynamic light caused less photosynthetic suppression, rather than more, under nitrogen deficit conditions than under sufficient nitrogen supply conditions in soybean

BMC Plant Biology, 2020
Background Plants are always exposed to dynamic light. The photosynthetic light use efficiency of leaves is lower in dynamic light than in uniform irradiance.

Growth in fluctuating light buffers plants against photorespiratory perturbations

Nature Communications, 2023
Photorespiration (PR) is the pathway that detoxifies the product of the oxygenation reaction of Rubisco. It has been hypothesized that in dynamic light environments, PR provides a photoprotective function. To test this hypothesis, we characterized plants

Proteomics analysis reveals a dynamic diurnal pattern of photosynthesis-related pathways in maize leaves. [PDF]

PLoS ONE, 2017
Plant leaves exhibit differentiated patterns of photosynthesis rates under diurnal light regulation. Maize leaves show a single-peak pattern without photoinhibition at midday when the light intensity is maximized.

Nitrogen Can Alleviate the Inhibition of Photosynthesis Caused by High Temperature Stress under Both Steady-State and Flecked Irradiance

Frontiers in Plant Science, 2017
Nitrogen is one of the most important elements for plants and is closely related to photosynthesis. High temperature stress significantly inhibits photosynthesis under both steady-state and flecked irradiance.

Evolution of gene regulatory network of C4 photosynthesis in the genus Flaveria reveals the evolutionary status of C3-C4 intermediate species

Plant Communications, 2023
C4 photosynthesis evolved from ancestral C3 photosynthesis by recruiting pre-existing genes to fulfill new functions. The enzymes and transporters required for the C4 metabolic pathway have been intensively studied and well documented; however, the ...

High-Resolution Dynamics of Hydrogen Peroxide on the Surface of Scleractinian Corals in Relation to Photosynthesis and Feeding

Frontiers in Marine Science, 2022
We developed and used a microsensor to measure fast (<1 s) dynamics of hydrogen peroxide (H2O2) on the polyp tissue of two scleractinian coral species (Stylophora pistillata and Pocillopora damicornis) under manipulations of illumination ...

Whole-tree water use efficiency is decreased by ambient ozone and not affected by O3-induced stomatal sluggishness. [PDF]

PLoS ONE, 2012
Steady-state and dynamic gas exchange responses to ozone visible injury were investigated in an ozone-sensitive poplar clone under field conditions. The results were translated into whole tree water loss and carbon assimilation by comparing trees exposed

Dynamic regulation of photosynthesis in Chlamydomonas reinhardtii [PDF]

The Plant Journal, 2015
SummaryPlants and algae have acquired the ability to acclimatize to ever‐changing environments to survive. During photosynthesis, light energy is converted by several membrane protein supercomplexes into electrochemical energy, which is eventually used to assimilate CO2.

Photosynthesis rates of seagrass and macroalgae measured in situ by pulse-amplitude modulated (PAM) fluorometry [PDF]

BIO Web of Conferences
Photosynthesis, a fundamental process, sustains coastal vegetated ecosystem services. Pulse-Amplitude Modulated fluorometry was a non-invasive method used to assess the photosynthetic efficiency of seagrass and macroalgae in dynamic coastal environments.
