Abstract

Specific events preceding cell division in the unicellular phytoflagellate Apedinella radians (Pedinellophyceae) were investigated ultrastructurally and by immunofluorescence microscopy. These events include the sequential formation and secretion of a duplicate set of elongate spine-scales, the duplication and development of basal bodies/flagella, the generation of two new dictyosomes at the future sites of spindle poles, and the constriction (not division) of chloroplasts. Actin and microtubules are involved in spine-scale formation, while actin alone appears to play a role during body scale formation. Both scale types are formed intracellularly within specialized vesicles located adjacent to the posterior cell membrane. The length of spine-scales is not limited by cell size, as they form within cell extensions. Following secretion, spine-scales remain attached below the equator of the cell, and are not deployed to their interphase positions until after the completion of cell division.
