Diatom genome reveals key role in biosphere's carbon cycle
...a diatom, she says. Nitrogen is crucial for diatom growth
and is often in short supply in seawater, depending on ocean conditions. The genome work revealed that the diatom Thalassiosira pseudonana has the genes to produce urea-cycle enzymes that may help to reduce its dependence on nitrogen from the surroun...
