Diatom genome helps explain success in trapping excess carbon in oceans
Date:10/15/2008

rse, so too is their behavior; for instance, the former get around by floating, the latter by gliding through the water or on surfaces.

The lifestyle of diatoms can be characterized as "bloom or bust." When light and nutrient conditions in the upper reaches of the ocean are favorable, particularly at the onset of spring, diatoms gain an edge and tend to dominate their phytoplankton brethren. When food is scarce, they die and sink, carrying their complement of carbon dioxide to the deeper recesses.

Bowler and his colleagues are also trying to understand the role that iron plays in the Phaeodactylum's development. Iron is even more precious than nitrogen in the ocean and its absence in the southern hemisphere is likely a major cause of oceanic deserts of photosynthesis there. Bowler's team has demonstrated that when iron deficiency occurs processes such as photosynthesis and nitrogen assimilation are suppressed. Other studies, which hail diatoms as champions in capturing carbon dioxide, suggest a bold strategy of using iron as a fertilizer to provoke massive diatom blooms. "Once they have feasted, the weight of their silicon shells, which resemble glass, causes the diatoms to sink to the bottom of the ocean when they die, and the carbon that they assimilated is trapped there for millennia," says Bowler. "By sequestering carbon in this way we could reverse the damage from the burning of fossil fuels."
