Fig. 4 in Morphological and Morphogenetic Redescriptions and SSU rRNA Gene-based Phylogeny of the Poorly-known Species Euplotes amieti Dragesco, 1970 (Ciliophora, Euplotida)

Fig. 4. Photomicrographs of Euplotes amieti during morphogenesis after protargol impregnation. (A) Ventral view of a middle divider showing the migration of cirri and the division of the macronucleus. (B, C) Ventral view of an early divider demonstrating two sets of frontal-ventral-transverse cirral streaks (arrowheads) and the oral primordium in opisthe (arrow). (D) To show new cirri derived from the frontal-ventral-transverse cirral anlagen. (E) Ventral view, arrows point to the paroral membrane (PM) in the proter and the development of the PM-anlage in the opisthe; arrowhead indicates the frontal cirrus I/1 in the opisthe formed de novo. (F) Ventral view, indicating the marginal anlagen of the proter (arrow) and the opisthe (arrowhead). (G) Arrowheads showing the dorsal kinety anlage of an early divider. (H) Portion of the ventral view, showing the marginal cirri in the proter (arrow) and the opisthe (arrowhead). (I) Dorsal view, arrowheads indicating the development of the dorsal kinety anlage. (J) Portion of the dorsal view, to show the newly formed caudal cirri in the proter (arrowheads). Scale bars: 100 μm.
