Diatoms are unicellular photosynthetic eukaryotes that play a major role in the global cycling
of carbon and silicon. They are believed to have arisen from a secondary endosymbiotic …

Gaseous carbon dioxide enters the biosphere almost exclusively via the active site of the
enzyme ribulose 1, 5-bisphosphate carboxylase/oxygenase (Rubisco). This highly …

The introduction of plastids into different heterotrophic protists created lineages of algae that
diversified explosively, proliferated in marine and freshwater environments, and radically …

Diatoms contain a secondary plastid that derives from a red algal symbiont. This organelle is
limited by four membranes. The two outermost membranes are the chloroplast endoplasmic …

Truncated hemoglobins (trHbs) are heme proteins found in bacteria, plants, and unicellular
eukaryotes. They are distantly related to vertebrate hemoglobins and are typically shorter …

Cyanidioschyzon merolae is considered to be one of the most primitive of eukaryotic
photosynthetic organisms. To obtain insights into the origin and evolution of the pathway of …

Marine planktonic diatoms are among the most important contributors to phytoplankton
blooms and marine net primary production. Their ecological success has been attributed to …

Diatoms are phytoplankton eukaryotic microalgae that are widely distributed in the world's
oceans and are responsible for 20–25% of total carbon fixation on the planet. Using …

Diatoms are one of the most successful eukaryotes. There are over 100,000 diatom species
contributing nearly half of total algal abundance in the oceans. Diatoms have conquered …

Background Diatoms, which are important planktons widespread in various aquatic
environments, are believed to play a vital role in primary production as well as silica cycling …
