The effect of water motion on short-term rates of photosynthesis by marine phytoplankton
TLDR
Phytoplankton respond to variations in light intensity as they are mixed through the water column to modulate the rate of photosynthesis in situ, which influences light harvesting and Calvin cycle activity.About:

Phytoplankton in a changing world: cell size and elemental stoichiometry
Zoe V. Finkel,John Beardall,Kevin J. Flynn,Antonietta Quigg,Antonietta Quigg,T. Alwyn V. Rees,John A. Raven +6 more
TL;DR: It is suggested that cell size and elemental stoichiometry are promising ecophysiological traits for modelling and tracking changes in phytoplankton community structure in response to climate change.

Photoacclimation of photosynthesis irradiance response curves and photosynthetic pigments in microalgae and cyanobacteria1
TL;DR: The photosynthesis‐irradiance response (PE) curve, in which mass‐specific photosynthesis rates are plotted versus irradiance, is commonly used to characterize photoacclimation and it is clear that maximizing the rate of photosynthetic carbon assimilation is not the only criterion governing photoac Climation.
Journal ArticleDOI
Photosynthetic architecture differs in coastal and oceanic diatoms
TL;DR: This work shows, using laboratory-cultured model species, a fundamental difference between a coastal and an oceanic diatom in their photosynthetic architecture, and suggests that diatoms exploited this difference in the underwater light climate between oceanic and coastal waters, enabling them to decrease their iron requirements without compromising Photosynthetic capacity.

Regulation and function of xanthophyll cycle-dependent photoprotection in algae
Reimund Goss,Torsten Jakob +1 more
TL;DR: The biochemistry of the xanthophyll cycle enzymes is addressed with a special focus on protein structure, co-substrate requirements and regulation of enzyme activity, and the interaction between the diadinoxanthin cycle and alternative electron flow pathways in the chloroplasts of diatoms is an additional topic of this review.
Journal ArticleDOI
Biodiversity of NPQ
Reimund Goss,Bernard Lepetit +1 more
TL;DR: The present day knowledge about NPQ in higher plants and different algal groups is summarized with a special focus on the molecular mechanisms that lead to the structural rearrangements of the antenna complexes and enhanced heat dissipation.

A dynamic regulatory model of phytoplanktonic acclimation to light, nutrients, and temperature
TL;DR: A new regulatory model can describe acclimation of phytoplankton growth rate, chlorophyll a : carbon ratio and nitrogen: carbon ratio to irradiance, temperature and nutrient availability and treats respiration as the sum of the maintenance metabolic requirement and the cost of biosynthesis.
Journal ArticleDOI
Light intensity regulation of cab gene transcription is signaled by the redox state of the plastoquinone pool
TL;DR: A model for a light intensity signaling system where cab gene expression is reversibly repressed by a phosphorylated factor coupled to the redox status of plastoquinone through a chloroplast protein kinase is proposed.
Journal ArticleDOI
Dynamic model of phytoplankton growth and acclimation: responses of the balanced growth rate and the chlorophyll a:carbon ratio to light, nutrient-limitation and temperature
TL;DR: In this article, a dynamic regulatory model was proposed to predict the dependencies of 8 and growth rate on irradiance, daylength, temperature and nutrient availability of the chlorophyll a:carbon ratio (g).
Journal ArticleDOI
Temperature regulation of nitrate uptake: A novel hypothesis about nitrate uptake and reduction in cool-water diatoms
TL;DR: In this paper, the authors conducted both NO uptake kinetics and direct short-term temperature manipulation studies on field diatom-dominated populations from Chesapeake and Delaware Bays during both spring and fall blooms.
