High Stomatal Conductance in the Tomato Flacca Mutant Allows for Faster Photosynthetic Induction
Frontiers in Plant Science, 2020 Due to their slow movement and closure upon shade, partially closed stomata can be a substantial limitation to photosynthesis in variable light intensities.

A System Dynamics Approach to Model Photosynthesis at Leaf Level Under Fluctuating Light
Frontiers in Plant Science, 2022 Photosynthesis has been mainly studied under steady-state conditions even though this assumption results inadequate for assessing the biochemical responses to rapid variations occurring in natural environments. The combination of mathematical models with

ON THE DYNAMICS OF PHOTOSYNTHESIS [PDF]
Journal of General Physiology, 1918 Minute amounts of photosynthesis in marine plants can be accurately measured by adding a little phenolphthalein to the sea water, and observing changes in the color of the indicator. In the case of fresh water aquatics bicarbonates are added. By this method it is found that Ulva which has been kept in the dark begins photosynthesis as ...

Frontiers in Plant Science, 2020 Leaf temperature changes with incident light intensity, but it is unclear how the concurrent changes influence leaf photosynthesis. We examined the time courses of CO2 gas exchanges and chlorophyll fluorescence of seedling leaves in four tropical tree ...

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.

Frontiers in Genetics, 2021 Microbial life in the oceans impacts the entire marine ecosystem, global biogeochemistry and climate. The marine cyanobacterium Prochlorococcus, an abundant component of this ecosystem, releases a significant fraction of the carbon fixed through ...

A small dynamic leaf-level model predicting photosynthesis in greenhouse tomatoes.
PLoS ONE, 2023 The conversion of supplemental greenhouse light energy into biomass is not always optimal. Recent trends in global energy prices and discussions on climate change highlight the need to reduce our energy footprint associated with the use of supplemental ...

Dynamic photosynthesis in different environmental conditions [PDF]
Journal of Experimental Botany, 2014 Incident irradiance on plant leaves often fluctuates, causing dynamic photosynthesis. Whereas steady-state photosynthetic responses to environmental factors have been extensively studied, knowledge of dynamic modulation of photosynthesis remains scarce and scattered.

Coral Symbiosis Carbon Flow: A Numerical Model Study Spanning Cellular to Ecosystem Levels
Frontiers in Marine Science, 2022 Corals rely on a symbiotic relationship with algae (zooxanthellae), which reside in the host tissue and play a critical role for host metabolism through photosynthesis, respiration, carbon translocation, and calcification.

Photosynthesis dynamics and regulation sensed in the frequency domain [PDF]
Plant Physiology, 2021 Abstract Foundations of photosynthesis research have been established mainly by studying the response of plants to changing light, typically to sudden exposure to a constant light intensity after dark acclimation or light flashes. This approach remains valid and powerful, but can be limited by requiring dark acclimation before time ...
