Figs 1–4. Light and ultrastructural aspects of the periphery of plasmodia of Myxobolus insignis infecting the freshwater teleost Semaprochilodus insignis from the Amazon River, showing the evolution of the plasmalemma during the three phases. 1 – light micrograph showing the smooth plasmalemma (arrowheads) of the plasmodium (P) in contact with the surrounding cells of the host (H). This aspect corresponds to stage 1 of the plasmodium development; 2 – ultrastructural aspect of the area boxed in Fig. 1, observed with higher magnification showing several collagen fibres (Cg) at the periphery of the plasmodium (P) and some vesicles (Ve) in the cortical zone of the plasmodium; 3 – light micrograph showing the plasmalemma containing several small microvilli (arrowheads). Internally, some immature (iS) and mature spores (mS) and vesicles are present and, externally, a layer of collagen fibres (Cg). This aspect corresponds to stage 2 of the plasmodium development; 4 – ultrastructural aspect of the plasmalemma and their microvilli (arrowheads) in contact with surrounding fibroblasts (Fb). Among the microvilli numerous collagen fibres are present. The cortical zone of the plasmodium (P) contains numerous vesicles (Ve), some of which seem to fuse with the plasmalemma.
Fig. 6. Maximum likelihood tree for 327 in Ultrastructure of Diplophrys parva, a New Small Freshwater Species, and a Revised Analysis of Labyrinthulea (Heterokonta)
Fig. 6. Maximum likelihood tree for 327 heterokonts emphasizing Labyrinthulea and Eogyrea of phylum Bigyra and the non-heterokont outgroups. Internal branches for the five clades at the top of the tree are collapsed, but are being published separately (Cavalier-Smith and Scoble in press); the numbers to their right indicate how many sequences were included in each. Bootstrap supports for bipartitions are based on 1,000 resamplings using GTRMIX option of RAxML. Black bullets indicate 100% bootstrap support. The sequence attributed to 'Labyrinthuloides haliotidis' might be from a thraustochytrid contaminant rather than from Aplanochytrium (=Labyrinthuloides) haliotidis (Leander and Porter 2001).
