Blue radiation stimulates photosynthetic induction in Fagus sylvatica L.

Photosynthetica, 2009
This study was designed to test the hypothesis that the spectral composition of incident radiation, as defined by the relative proportions of blue (B; λmax = 455 nm) and red (R; λmax = 625 nm) photons, can affect photosynthetic induction, since B photons stimulate stomatal opening and are more effectively absorbed by leaves than R photons.

Speed of light-induced stomatal movement is not correlated to initial or final stomatal conductance in rice

Photosynthetica, 2022
In nature, plants are often confronted with wide variations in light intensity, which may cause a massive carbon loss and water waste. Here, we investigated the response of photosynthetic rate and stomatal conductance to fluctuating light among ten rice ...

Effect of Cameraria ohridella feeding on Aesculus hippocastanum photosynthesis

Regulatory Mechanisms in Biosystems, 2021
The complex of invasive species of phytophagous insects that can adapt to novel living conditions is constantly increasing. The ecological effect of their vital activity in the new environment is almost impossible to predict.

Effects of saturation flash protocols on photosynthetic induction and assessment of mesophyll conductance and maximum carboxylation rate sensitivity to parameter inputs in Ficus carica

Frontiers in Plant Science
Improving photosynthetic efficiency during the induction phase is a key strategy for enhancing plant productivity. A critical prerequisite for achieving this goal is identifying the limitation factors that affect photosynthesis during induction.

C4 monocots and C4 dicots exhibit rapid photosynthetic induction response in contrast to C3 plants.

Physiologia Plantarum : An International Journal for Plant Biology
Considering the prevalence of ever-changing conditions in the natural world, investigation of photosynthetic responses in C4 plants under fluctuating light is needed. Here, we studied the effect of dynamic illumination on photosynthesis in totally 10 C3,

Induction of the photosynthetic membranes of Rhodopseudomonas sphaeroides: biochemical and morphological studies [PDF]

Journal of Bacteriology, 1984
Cells of Rhodopseudomonas sphaeroides grown in a 25% O2 atmosphere were rapidly subjected to total anaerobiosis in the presence of light to study the progression of events associated with the de novo synthesis of the inducible intracytoplasmic membrane (ICM).

Respiration Interacts With Photosynthesis Through the Acceptor Side of Photosystem I, Reflected in the Dark-to-Light Induction Kinetics of Chlorophyll Fluorescence in the Cyanobacterium Synechocystis sp. PCC 6803

Frontiers in Plant Science, 2021
In cyanobacteria, the photosynthetic prokaryotes, direct interaction between photosynthesis and respiration exists at plastoquinone (PQ) pool, which is shared by the two electron transport chains.

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.

Hyperpolarization electrical signals induced by local action of moderate heating influence photosynthetic light reactions in wheat plants

Frontiers in Plant Science, 2023
Local action of stressors induces fast changes in physiological processes in intact parts of plants including photosynthetic inactivation. This response is mediated by generation and propagation of depolarization electrical signals (action potentials and
