Cell death in algae: physiological processes and relationships with stress
Berges, John A.; Choi, Chang Jae
Abstract Algae of many taxa show evidence of intrinsically-driven mortality (cell death), especially in response to environmental stresses. Such cell death shows some similarities to forms described in animals and plants (e.g. apoptosis and necrosis), but clear definitions are elusive, even in these multicellular groups. Accumulating physiological and molecular evidence suggests that the roots of cell death pathways are deep and some elements are widely conserved. Examining cell death in the evolutionarily diverse, yet more ecologically- and physiologically-conserved algae offers substantial advantages. Particularly useful lines of research may include gene knock-downs and over-expressions studies, emphasis on biochemical characterization of cell death pathways and individual-based modeling.
