MetabolomicsMetabolic adaptation of diatoms to hypersalinity

Microalgae are important primary producers and form the basis for the marine food web. As global climate changes, so do salinity levels that algae are exposed to. A metabolic response of algal cells partly alleviates the resulting osmotic stress. Some metabolites involved in the response are well...

MetabolomicsMetabolic consequences of cobalamin scarcity in diatoms as revealed through metabolomics (Thalassiosira pseudonana study)

Diatoms perform about 20% of photosynthesis on earth, play a crucial role in forming the base of the marine food web, and sequester anthropogenic carbon into the deep ocean through the biological pump. In some areas of the ocean, diatom growth is limited by the organic micronutrient cobalamin (vi...

MetabolomicsPronounced uptake and metabolism of organic substrates by diatoms revealed by pulse-labeling metabolomics
Diatoms contribute as a major group of microalgae to approximately 20% of the global carbon fixation. In the plankton, these algae are exposed to a plethora of metabolites, especially when competing algae are lysed. In line with evidence that these phototrophs can also engage in heterotrophy we aske...

MetabolomicsMetabolic profiling with UPLC-MS orbitrap of diatoms Coscinodiscus granii infected with parasitic oomycete Lagenisma coscinodisci
The bloom-forming diatoms Coscinodiscus granii were cultivated in a non-contact dual cultivation apparatus. This device allows the exchange of exudates, without transfer of any microorganisms, allowing the investigation of both endo- and exo-metabolome. The treatment consisted in infecting diatom ce...

TranscriptomicsMarine diatoms sense and respond to microscale turbulence in non-limiting nutrient conditions
According to the present theories, in nutrient-repleted conditions diatoms should not be affected by turbulence. We made laboratory experiments to demonstrate that two chain forming diatoms sense and respond to turbulence by varying their chain length spectra and tuning their metabolism. We compared...

ProteomicsPhosphorus-Ca2+ signalling in marine diatoms
Phosphorus is a critical nutrient controlling phytoplankton growth. Availability of this limiting factor can vary significantly in space and time, particularly in dynamic aquatic ecosystems. Diatoms are important eukaryotic phytoplankton that thrive in regions of pulsed phosphate supply, yet little ...
