Figure 3 in Morphology and morphogenesis of a soil urostylid ciliate, Paragastrostyla terricola (Foissner, 1988) Berger, 2006 (Ciliophora: Hypotrichia)

Figure 3. (A–D) Morphogenesis of Paragastrostyla terricola after protargol staining. (A,B) Ventral and dorsal view of a late divider, to show the infraciliature. Arrowheads point to the newly formed caudal cirri. Frontoventral cirri originating from the same anlagen are connected by dotted lines. (C,D) Ventral and dorsal view of a reorganiser, arrowheads (in D) indicate the newly formed caudal cirri and arrows (in D) show dorsal kineties anlagen. FVTA = frontoventral cirral anlagen; LMA = left marginal anlagen; LMR = left marginal row; Ma = macronuclear nodules; Mi = micronuclei; OP = oral primordium; RMA = right marginal anlagen; RMR = right marginal row; 1, 2 = dorsal kineties 1, 2. Scale bars: A– D = 40 μm.
