Figs 3A–F in Systematic Analyses of the Genus Architricha and Pleurotricha curdsi (Ciliophora, Oxytrichidae), with Redescriptions of Their Morphology

Figs 3A–F. Photomicrographs of protagol stained cells of Architricha indica during regenerative (A–C) and morphogenetic stages (D–F). A, B – ventral (A) and detailed dorsal (B) view of cell during early stage of reorganization, showing the formation of oral primordium (OP), the frontoventral-transverse cirral (FVT) anlagen and dorsal kineties anlagen (arrowheads); C – anterior part of ventral side of another regenerating cell, showing the anlage V arose from the cirrus IV/2 (arrowhead); D – ventral view, showing the six streaks of FVT anlagen; E, F – ventral (E) and dorsal (F) detailed view, showing the FVT anlagen dividing into fragments, the dedifferentiation of parental undulating membranes and the origin of multiple marginal rows in (E) and showing the anlagen for dorsal kineties in (F), arrowheads showing the new frontal cirri that came from the undulating membranes anlage. DKA – dorsal kinety anlagen, FVTA – frontoventral-transverse cirral anlagen, I–V – FVT I to V, LMA – left marginal row anlagen, OP – oral primordium, RMA – right marginal anlagen, UMA – undulating membranes anlage. Scale bars: 50 μm.
