Scientists sequence genome of kind of organism central to biosphere's carbon cycle
...a diatom, she says. Nitrogen is crucial for diatom growth
and is often in short supply in sea water, depending on ocean conditions. The genome work revealed that diatom Thalassiosira pseudonana has the genes to produce urea-cycle enzymes that may help to reduce its dependence on nitrogen from the surroundin...
Safety of isoflavones in dietary supplements targeted by Illinois initiative
