A penalty on photosynthetic growth in fluctuating light [PDF]

Scientific Reports, 2017
AbstractFluctuating light is the norm for photosynthetic organisms, with a wide range of frequencies (0.00001 to 10 Hz) owing to diurnal cycles, cloud cover, canopy shifting and mixing; with broad implications for climate change, agriculture and bioproduct production.

Photoprotection of photosystems in fluctuating light intensities [PDF]

Journal of Experimental Botany, 2014
Oxygenic photosynthetic organisms experience strong fluctuations in light intensity in their natural terrestrial and aquatic growth environments. Recent studies with both plants and cyanobacteria have revealed that Photosystem (PS) I is the potential target of damage upon abrupt changes in light intensity.

Role of Equilibrium Fluctuations in Light-Induced Order

Physical Review Letters, 2021
Engineering novel states of matter with light is at the forefront of materials research. An intensely studied direction is to realize broken-symmetry phases that are "hidden" under equilibrium conditions but can be unleashed by an ultrashort laser pulse. Despite a plethora of experimental discoveries, the nature of these orders and how they transiently

Photosynthetic Light-use Efficiency in Rice (Oryza sativa L.) Leaf under Light with Fluctuating Intensities at Two Different Ambient Humidities

Plant Production Science, 2000
Photosynthetic and transpiration rates of rice leaf were measured under light with an intensity fluctuating in a wide range of frequencies (2.8 × 10–4∼4 Hz). The time course of photosynthetic rate differed with the frequency.

Photorespiration plays an important role in the regulation of photosynthetic electron flow under fluctuating light in tobacco plants grown under full sunlight

Frontiers in Plant Science, 2015
Plants usually experience dynamic fluctuations of light intensities under natural conditions. However, the responses of mesophyll conductance, CO2 assimilation, and photorespiration to light fluctuation are not well understood.

Photosynthetic light‐use efficiency of rice leaves under fluctuating incident light

Agrosystems, Geosciences & Environment, 2020
The responsiveness of photosynthesis to continuously fluctuating light intensities can provide an estimate of the net assimilation rate (A) and photosynthetic light‐use efficiency (PLUE), which cannot be measured under steady‐state conditions. This study

Effects of Artificially Reproduced Fluctuations in Sunlight Spectral Distribution on the Net Photosynthetic Rate of Cucumber Leaves

Frontiers in Plant Science, 2021
The effects of photosynthetic photon flux density (PPFD) fluctuations in sunlight have already been investigated; however, the spectral photon flux density distribution (SPD) has hardly been considered.

Plasticity of Arabidopsis rosette transcriptomes and photosynthetic responses in dynamic light conditions

Plant Direct, 2023
With the high variability of natural growth environments, plants exhibit flexibility and resilience in regard to the strategies they employ to maintain overall fitness, including maximizing light use for photosynthesis, while simultaneously limiting ...

Photosynthetic Acclimation to Fluctuating Irradiance in Plants

Frontiers in Plant Science, 2020
Unlike the short-term responses of photosynthesis to fluctuating irradiance, the long-term response (i.e., acclimation) at the chloroplast, leaf, and plant level has received less attention so far.
