Fig. 4. A–F in Morphogenesis and Molecular Characterization of a Little Known Soil Ciliate, Oxytricha nauplia Berger et Foissner, 1987 (Ciliophora, Sporadotrichida)

Fig. 4. A–F. Morphogenesis of Oxytricha nauplia after protargol staining. (A, B) Ventral and dorsal views of the same mid-divider, arrowheads in A mark the dorsomarginal kineties anlagen and in B show the posterior fragmentation of the third dorsal kinety anlage (counted from left to right), arrows in B show the old caudal cirri. (C, D) Ventral and dorsal views of the same late divider, (C) shows the completely formed frontoventral-transverse cirri and (D) shows the caudal cirri (arrowheads). (E, F) Ventral and dorsal views of the same late divider just before cell division, to show the newly built ciliature and nuclear apparatus. AZM = adoral zone of membranelles; DK1, 2, 3, 4, 5 = dorsal kinety 1, 2, 3, 4, 5; LMC = left marginal cirri; TC = transverse cirri; I to VI represent anlagen I to VI. Scale bars = 30 μm.
