The microalga Phaeocystis globosa is recognized as a harmful alga and also one of the few keystone phytoplankton genera that shape the structure and function of marine ecosystems. P. globosa possess a complex polymorphic life cycle, exhibiting phase alternation between free-living cells of approximately 3–6 μm in diameter and gelatinous colonies (palmelloid stage) reaching several millimeters. The knowledge on the factors that induced the morphological transition of P. globosa in the last two decades was reviewed. Emphasis is given to infochemicals, an additional biological factor induced by predator, with the attempt to reveal a relevant mechanism of induced morphological defense.
Key words:    Phaeocystis globosa|polymorphisms|harmful algal blooms|defense strategies|infochemical
