Only a limited number of studies exist on the life cycles of non-model ciliates such as Chilodonella uncinata (Cl: Phyllopharyngea). The handful of papers on this taxon indicates the presence of a heteromeric macronucleus, marked by separate DNA rich and DNA poor regions. Here, we study the life cycle of C. uncinata using confocal laser scanning microscopy with DAPI staining, which allows us to differentiate nuclear dynamics of the micronucleus and the macronucleus during life cycle stages. We photo-documented various stages and confirm aspects of the development of the new macronucleus previously characterized by electron microscopy. We further reveal the heteromeric structure of the macronucleus with Z-stacks and 3D reconstructions. We find no evidence for the presence of an endosome at the center of the macronucleus during vegetative growth. In addition to illustrating the life cycle of this ciliate, the approaches developed for this study will enable additional comparative analyses of nuclear dynamics using fluorescence microscopy.
