How do phytoplankton survive a scarcity of a critical nutrient?
Date:6/5/2014

Phytoplanktontiny, photosynthetic organismsare essential to life on Earth, supplying us with roughly half the oxygen we breathe. Like all other life forms, phytoplankton require the element phosphorus to carry out critical cellular activity, but in some parts of the world's ocean, P is in limited supply. How do phytoplankton survive when phosphorus is difficult to find?

Phytoplankton can alter their biochemical make-up according to the availability of nutrients in the water. When phosphorus (P) is particularly abundant in the water, phytoplankton produce and store a form of P called polyphosphate, or poly-P, to use later during times when P is less abundant. The accepted wisdom has been that poly-P was would be found stored by micro-organisms in waters where P was abundant and would be scarce in waters depleted of P. But when a group of researchers from the Woods Hole Oceanographic Institution (WHOI) and the Bigelow Laboratory for Ocean Sciences tested that notion, conducting the most comprehensive survey of poly-P content and distribution in the western North Atlantic, what they found was surprising.

Rather than finding low levels of poly-P in the phytoplankton in the Sargasso Sea where P is scarce, they found the phytoplankton were enriched with poly-P when compared to those in the nutrient rich waters in the western North Atlantic the opposite of what they had expected. They also found that in low-P environments, poly-P was more readily recycled from sinking particles, retaining it in shallower waters where phytoplankton live and making it available for their use.

"We've know that Poly-P existed in phytoplankton for a very long time. The conventional wisdom that phytoplankton made more Poly-P when they had more phosphorus just made so much intuitive sense that few people have worked on this molecule," said WHOI marine chemist Ben Van Moy, the corresponding author on the study. "However, there were a few hints in the lite
