Functional Characterization of the Monogalactosyldiacylglycerol Synthase Gene ptMGD2 in the Diatom Phaeodactylum tricornutum

Frontiers in Marine Science, 2022
Monogalactosyldiacylglycerol (MGDG) is the most abundant polar lipid in thylakoid membrane, wherein it plays critical roles related to thylakoid membrane assembly and function in diatoms. However, diatom MGDG biosynthesis has not been fully characterized.

Architectural and biochemical advances in understanding microbial CO2 concentrating mechanisms

The Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY CO2 concentrating mechanisms (CCMs) are ubiquitous in phototrophs. They are found in the micro as well as the macro world. Different domains of life have developed strikingly different approaches to concentrate inorganic carbon around Rubisco, the most prevalent enzyme on earth.

Comparative Genomics of the Pennate Diatom Phaeodactylum tricornutum   [PDF]

Plant Physiology, 2005
Abstract Diatoms are one of the most important constituents of phytoplankton communities in aquatic environments, but in spite of this, only recently have large-scale diatom-sequencing projects been undertaken. With the genome of the centric species Thalassiosira pseudonana available since mid-2004, accumulating sequence information for ...

Diatoms–copepods: An evolutionary arms race

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Diatoms and copepods are dominating and diverse groups of phytoplankton and zooplankton, respectively. Diatoms account for 25–40% of ocean primary production, and their main predators, copepods, are arguably the most abundant group of metazoans in the ocean, typically accounting for ~ 80% of zooplankton biomass.

Photoacclimation strategies in Phaeodactylum tricornutum biofilms

Algal Research
Microalgal biofilms are a promising alternative to conventional suspended cultures, offering increased biomass densities with reduced water and energy demands for cultivation and harvesting. However, to fully demonstrate their interest for large-scale production, a better understanding of the impact of operational factors on biofilm structure is ...

Phosphorus Acquisition Strategies Among Phytoplankton and Free‐Living Bacterial Communities in the Baltic Proper

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Phosphorus is a key element for cellular functions and poses significant challenges for planktonic microbial communities under limited availability. Metagenomics highlighted that heterotrophic bacteria predominantly relied on phosphate scavenging while eukaryotic phytoplankton primarily utilized membrane remodelling to cope with limited phosphorus ...

Integrated Regulatory and Metabolic Networks of the Marine Diatom Phaeodactylum tricornutum Predict the Response to Rising CO₂ Levels

mSystems, 2017
Diatoms are eukaryotic microalgae that are responsible for up to 40% of the ocean’s primary productivity. How diatoms respond to environmental perturbations such as elevated carbon concentrations in the atmosphere is currently poorly understood.
