Plants, 2020 Natural light intensities can rise several orders of magnitude over subsecond time spans, posing a major challenge for photosynthesis. Fluctuating light tolerance in the green alga Chlamydomonas reinhardtii requires alternative electron pathways, but the

Plant Direct, 2023 Fluctuating light intensity challenges fluent photosynthetic electron transport in plants, inducing photoprotection while diminishing carbon assimilation and growth, and also influencing photosynthetic signaling for regulation of gene expression.

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.

Does Fluctuating Light Affect Crop Yield? A Focus on the Dynamic Photosynthesis of Two Soybean Varieties [PDF]
Frontiers in Plant Science, 2022 In natural environments, plants are exposed to variable light conditions, but photosynthesis has been mainly studied at steady state and this might overestimate carbon (C) uptake at the canopy scale.

Cells, 2021 Fluctuating light can cause selective photoinhibition of photosystem I (PSI) in angiosperms. Cyclic electron flow (CEF) around PSI and electron flux from water via the electron transport chain to oxygen (the water-water cycle) play important roles in ...

Responses of photosystem I compared with photosystem II to fluctuating light in the shade-establishing tropical tree species Psychotria henryi [PDF]
Frontiers in Plant Science, 2016 Shade-establishing plants growing in the forest understory are exposed to constant high light or fluctuating light when gaps are created by fallen trees.

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.

Light intensity affects leaf morphology in a wild population of Adenostyles alliariae (Asteraceae) [PDF]
Italian Botanist, 2019 Low light conditions can impose environmental stress on plants, and plants often respond adaptively by increasing their leaf area. Light stress on plants can also result in developmental instability, which can manifest as increased fluctuating asymmetry ...

Antioxidants, 2022 Fluctuating light (FL) can cause the selective photoinhibition of photosystem I (PSI) in angiosperms. In nature, leaves usually experience FL conditions with the same low light and different high light intensities, but the effects of different FL ...
