Polarity: the role of localized secretion.
Studies of single cells from brown algae suggest that localized secretions stabilize the polar axis resulting in an asymmetry in the cell wall. This cortical asymmetry appears to play a role in orienting the plane of cell division and in determining the different fates of the resulting daughter cells. Recent studies indicate that similar processes may operate in seed plants.
