Short summary

Phaeocystis antarctica is an important phytoplankter of the Antarctic coastal environment where it dominates the early season bloom after sea ice retreat. Iron nutrition was found to be an important factor that results in Phaeocystis colony formation and a large restructuring of the proteome, including changes associated with the flagellate to colonial transition and adaptive responses to iron scarcity. Analysis of Phaeocystis proteins from the Ross Sea revealed the presence of both cell types.
