By adapting different approaches of high-resolution cellular imaging applied to diatom Phaeodactylum tricornutum, the scientists were able to develop a 3D model of the photosynthetic system of diatoms. They observed the existence of micro-domains which, just like in plants, separate the two photosystems, allowing for even more efficient photosynthesis. All these results explain how diatoms produce about 20% of oxygen released daily on Earth, and why they have colonized the oceans for the last 100 million years.
The researchers are continuing to develop this 3D model of photosynthesis in diatoms, which will enable them to better understand how these single cell organisms will adapt to the consequences of climate change.
This result was the subject of a press release.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
