Fig. 12 in Some Ultrastructural Features of the Planktonic Freshwater Ciliate Limnostrombidium viride (Alveolata, Ciliophora, Oligotrichida) and Improved Diagnoses of Oligotrich Taxa

Fig. 12. Neoformation organelles in dividers of Limnostrombidium viride in the transmission electron microscope. (A) Oblique section of the organelle's distal (asterisk) and proximal portions with the outgrowing cilia of the oral primordium. The axonemes (arrowheads) are very short, lack the central pair of microtubules, and are bulbous because being embedded in many vesicles. (B) Cross section of cilia. Their axonemes already possess the "9×2+2" ultrastructure (arrowheads). (C) Tangential section of the neoformation organelle showing cross sections of cilia (arrowheads) and vesicles with electron-dense content of unknown function. (D) Longitudinal section of the posterior cell portion. Both the unciliated (arrowhead) and ciliated (double arrowhead) portions of the organelle are shown twice in cross section. MB, cell membrane; PE, perilemma; V, vesicles. Scale bars: 1 µm (A–C), 5 µm (D).

Fig. 11. Ring-canal of Limnostrombidium viride in the transmission electron microscope. The transverse section of the organelle shows its position between the anterior furrow (asterisk) and the stripe of extrusome attachment sites (arrow denotes the electron-dense cap of an empty "extrusome chamber"). Vesicles are adjacent to the irregular anterior membrane portion of the canal, while the posterior portion is underlain by two layers of perpendicularly orientated microtubules. ML, two layers of microtubules; PE, perilemma; RC, lumen of ringcanal; V, vesicles of unknown function. Scale bar: 1 µm.

(B, C) Transverse and longitudinal sections; white lines mark corresponding section planes. The extrusome shows in longitudinal section an electron-dense fusiform wall and an electron-light lumen with indistinct transverse stripes. The apical portion of the extrusome is surrounded by an electron-dense structure; both are enclosed by a membrane (arrowheads). The transverse section shows the extrusome to be composed of six electron-dense trapeziums arranged around a bright lumen. 1, attachment rosette with one central and eight peripheral particles; 2, first ring; 3, second ring; ED, electron-dense structure; EX, extrusomes. Scale bars: 1 µm.

Fig. 3 in Some Ultrastructural Features of the Planktonic Freshwater Ciliate Limnostrombidium viride (Alveolata, Ciliophora, Oligotrichida) and Improved Diagnoses of Oligotrich Taxa

Fig. 3. Oral ciliature of Limnostrombidium viride in the scanning (A) and transmission electron microscopes (B–D). (A) Proximal portion of the adoral zone of membranelles. The endoral membrane is usually covered by a cytoplasmic fold and a membranous sheet (probably perilemma). (B) Longitudinal section of the buccal lip and endoral membrane in ventral view. Note the numerous vesicles with fluffy content of unknown nature in the anterior cell half and especially in the buccal lip. The perilemma forms stacks in the buccal cavity, while it otherwise covers the cell only with a single layer. (C) Longitudinal section of the buccal vertex near the cytostome. The distal ends of the endoral cilia have modified axonemes (arrowhead), i.e., they have a reduced number of peripheral microtubular doublets. Some cilia of the buccal membranelles and the multiple membranes are also recognisable. (D) Transverse section of the basal bodies of the endoral membrane (seen from inside the buccal cavity). BL, buccal lip; BM, buccal membranelles; CM, collar membranelles; E, endoral membrane; ED, electron-dense bodies; LM, bifurcated left microtubular ribbons; NE, possibly nematodesmata; PE, perilemma; RM, right microtubular ribbons. Scale bars: 10 µm (A), 1 µm (B–D).
