In aquatic environments, phytoplankton represent a major source of reactive oxygen species
(ROS) such as superoxide and hydrogen peroxide. Many phytoplankton taxa also produce …

Like all aerobic organisms, plants and algae co-opt reactive oxygen species (ROS) as
signalling molecules to drive cellular responses to changes in their environment. In this …

Chloroplasts communicate information by signalling to nuclei during acclimation to
fluctuating light. Several potential operating signals originating from chloroplasts have been …

Diatoms are one of the most ecologically successful classes of photosynthetic marine
eukaryotes in the contemporary oceans. Over the past 30 million years, they have helped to …

Diatoms dominate nearly half of current oceanic productivity, so their responses to ocean
acidification are of general concern regarding future oceanic carbon sequestration …

Reactive oxygen species (ROS) have long been recognized as compounds with dual roles.
They cause cellular damage by reacting with biomolecules but they also function as agents …

Severe environmental stress imposed on plant tissues induces changes in oxygen (O2)
metabolism that cause oxidative stress. Oxidative stress occurs when reactive oxygen …

Lipid production in microalgae is highly dependent on the applied light intensity. However,
for the EPA producing model-diatom Phaeodactylum tricornutum, clear consensus on the …

Within natural waters, photodependent processes are generally considered the predominant
source of reactive oxygen species (ROS), a suite of biogeochemically important molecules …

Little is known on the antioxidant activity modulation in microalgae, even less in diatoms.
Antioxidant molecule concentrations and their modulation in microalgae has received little …
