Organisation of the digestive, excretory and reproductive systems in cysts of Thulinius ruffoi
<p>The data show the organisation of the digestive, excretory and reproductive systems in cysts of T. ruffoi at specific and unspecified stages of encystment. Text files contain additional technical information.</p>
Figures 27–30 in Cell structure and microtubule organisation during gametogenesis of Ulva mutabilis Føyn (Chlorophyta)
Figures 27–30: Tubulin immunofluorescence in released gametes of Ulva mUtabilis. (27) Released gamete bearing two equal flagella. Note that cortical microtubule bundles (tubulin fluorescence) extend from basal body towards the posterior. Scale bar: 20 µm. (28) Differential interference contrast microscopy-image of gamete in Figure 27. Scale bar: 20 µm. (29 and 30) Two gametes in which (apart from the two flagella) an intensely fluorescent microtubule bundle starting from flagellar basal body is directed to cytoplasm (arrows). Scale bar: 20 µm.
Figures 5–8 in Cell structure and microtubule organisation during gametogenesis of Ulva mutabilis Føyn (Chlorophyta)
Figures 5–8: Transmission electron micrographs of cells of Ulva mUtabilis 48 h after the induction of gametogenesis. (5) The cell is polarised with most of the cytoplasm and organelles gathered at the tip area. The external cell wall has formed a projection towards the apical region. The cell wall appears differentiated at this area (N: nucleus). Scale bar: 2 µm. (6) Detail of the apical wall of the previous image, showing the loose structure of the wall and the formation of amorphous dark-stained material. Scale bar: 0.35 µm. (7) More advanced stage of a wall projection. The dark-stained material covers the projection, while its central part appears as a plug, consisting of amorphous material. The internal wall layer under the tip is considerably thickened and pushes the plug out (asterisk). Scale bar: 4 µm. (8) Cross-section of a cell with a plug-like cap. The dark-stained material is extended covering the cap. Scale bar: 0.33 µm.
Figures 9–14 in Cell structure and microtubule organisation during gametogenesis of Ulva mutabilis Føyn (Chlorophyta)
Figures 9–14: Immunolocalization of tubulin in developing gametangia of Ulva mUtabilis. (9) Interphase cell before induction of gametogenesis. The microtubules are mainly peripherally arranged in more or less parallel bundles. Scale bar: 20 µm. (10) Early stage, 36–48 h after induction of gametogenesis. Intensely fluorescent microtubule bundles traverse the cortical cytoplasm converging on a particular area (arrow localises the conical cell projection). Scale bar: 20 µm. (11) More advanced stage, 48–60 h after induction of gametogenesis, showing microtubules starting from a pointed site at basal part of gametangium. Scale bar: 20 µm. (12) Αdvanced stage, 48–60 h after induction of gametogenesis, showing microtubules organised in a basketlike configuration, leaving a circular opening at the top (arrow). Scale bar: 20 µm. (13) Gametangium, 60–72 h after induction of gametogenesis. The microtubule-free area at the top appears broader than before (arrow). Scale bar: 20 µm. (14) Hoechst 33258 staining of the nucleus of the cell in Figure 12. Scale bar: 20 µm.
Figures 2–4 in Cell structure and microtubule organisation during gametogenesis of Ulva mutabilis Føyn (Chlorophyta)
Figures 2–4: Vegetative cells of Ulva mUtabilis before induction of gametogenesis. (2) Light micrograph of a semithin section showing a unilayered thallus. Note the difference in staining between external and internal cell wall layer. Scale bar: 20 µm. (3) Transmission electron micrograph of a thallus cell before induction of gametogenesis. The nucleus (N) has a relatively central position and the chloroplast (CHL) occupies a large part of the cytoplasm (CYT). Note the thick external wall. Scale bar: 3.6 µm. (4) Detail of external wall of a cell before induction of gametogenesis. Wall shows strict stratification, i.e. a thick internal amorphous layer, a median region with multiple fibrillar layers and an external dark-stained region (see brackets). Scale bar: 1 µm.
Figure 1 in Cell structure and microtubule organisation during gametogenesis of Ulva mutabilis Føyn (Chlorophyta)
Figure 1: Time course of induced gametogenesis and discharge of gametangia from Ulva mUtabilis in relation to the swarming inhibitor (SWI) synthesis and action (summary of new and previous results). Gametogenesis was induced in Ulva mUtabilis [mutant slender sl-G(mt +)]. The "determination phase" and "differentiation phase" are defined as described by Stratmann et al. (1996). The "swarming phase" is the time period when gamete release can be induced by light or a medium change, or may occur later spontaneously. (A) Regular vegetative G1 cell cycle phase in which gametogenesis can be induced by the removal of sporulation inhibitors SI-1 and SI-2 from the medium. (B) Regular vegetative S phase in which the genome is replicated normally or, after induction of gametogenesis, the period of SWI synthesis and excretion. (C) Next G1 phase after induction of gametogenesis. (D) Next S phase after induction of gametogenesis and accumulation of starch granules. (E) Time of irreversible commitment to gametangium differentiation. (F) Period of progamete formation, chloroplast reorientation and papilla initiation. (G) Period of progamete multiplication to 16 cells, and papilla maturation. (H) Period of gamete and pore cap maturation. (I) Period when the exit pores are open and when gamete release can be induced by light and/or depletion of SWI in the medium. (J) Period when the gametangia become insensitive to SWI and gamete release may occur spontaneously and asynchronously. Figure is from Wichard and Oertel (2010) with permission of © Wiley 2010. Images show the transformation of blade cells into gametangia. Microscopic images for stages a, f, h and i are shown (scale bars: 25 µm).

Datenanhang zu Ergebnisse der ZKI Top Concerns-Umfrage des ZKI-Arbeitskreises Strategie und Organisation für das Jahr 2017/18
<p>Der Arbeitskreis Strategie und Organisation des ZKI-Vereins führt eine jährliche Umfrage zu den wichtigsten Themen und Schwerpunkten der Mitgliedseinrichtungen durch. Im Jahr 2016 wurde die Umfrage auf eine elektronische Umfrage im Web mittels Lime-Survey umgestellt. Basierend auf dieser ersten Ergebnismenge konnte im Herbst 2017 eine erweiterte Umfrage durchgeführt werden, die auch einen Vergleich zum Vorjahr und die Relevanzverschiebungen bei den Top-Themen berücksichtigt. Der Artikel stellt die Kernergebnisse dar und wird durch die aufbereiteten Rohdaten im Excel-Format ergänzt.</p>
