Figure 4. Morphogenesis and reorganisation of Uncinata bradburyae from protargol staining. (A) A small part of a middle divider, showing analgen for right dorsal kineties and right marginal row, arrow indicates the dedifferentiation of a parental cirrus in the middle part of right marginal row; (B) ventral view of a late divider, showing the development of cirri and new membranelles in both proter and opisthe, arrow and arrowhead indicate the leftmost frontal cirrus and buccal cirrus, respectively; inset: anlagen for right dorsal kineties almost formed de novo in subpellicular pounch close to the parental rightmost dorsal kinety; (C) part of a middle divider, showing two kinds of anlagen for dorsal kineties formed de novo; (D) part of a middle divider, showing fused macronuclear mass, micronuclei (arrowheads) and the anlagen for left dorsal kineties right of the parental leftmost dorsal kinety; (E) part of a late divider, showing two dorsal kinety anlagen each with five streaks visible at right of the parental rightmost dorsal kinety at two levels, two macronuclear nodules (arrows) and micronuclei (arrowheads); (F) a mid-reorganiser, showing the development of cirral anlagen and oral primordium, arrowhead indicates the leftmost frontal cirrus, inset: oral primordium in subcortical pounch; (G) a late reorganiser, showing new oral and somatic ciliature are almost formed, arrow indicates two frontoterminal cirri migrated to the mid-body of cell, inset: the anlagen for right dorsal kineties; (H) a very late reorganiser, showing all new structures are almost finally positioned. FAM, frontal adoral membranelles; FTC, frontoterminal cirri; LDA, left doral kinety anlage; LMA, left marginal anlage; LMR, left marignal row; RDA, right dorsal kienty anlage; RMA, right marginal anlage; RMR, right marginal row; VAM, ventral adroal membranelles; TC, transverse cirri. Scale bars: 50 μm.
