Research Abstract

In this study, we investigated uniting of cells and filament formation in binary fission type species in Trebouxiophyceae. We used LM, TEM and FE-SEM to explore mother cell wall exfoliation. The mother cell wall was cleaved but remained adhered to the daughter cell in Stichococcus bacillaris. We observed that cells of S. bacillaris united each other and formed long filaments in log phase. The parallel emergence of multicellular algal species may have begun from processes such as filament formation.
