[Ab] Resumo:The hypotrich Schmidingerothrix elongata spec. nov., discovered in saline (20‰) soil of the Longfeng Wetland, Daqing, northern China, was studied using live observation and protargol impregnation. It is characterized, inter alia, by colorless cortical granules arranged in short rows, three frontoventral cirral rows with the rightmost extending far posteriorly, and 4-8, usually six macronuclear nodules. Cell division proceeds as in congeners and confirms the lack of dorsal ciliature. In phylogenetic analyses based on SSU rDNA, S. elongata is sister of S. salinarum+Paracladotricha salina. A re-investigation of the type slides of P. salina, type of Paracladotricha, revealed a misobservation in the original description. Since P. salina lacks, like Schmidingerothrix spp., a dorsal ciliature, Paracladotricha becomes a junior, subjective synonym of Schmidingerothrix with S. salina comb. nov. as fourth species. A review of the phylogenetic analyses dealing with Schmidingerothrix shows that its position is variable. However, together with the gonostomatid oral apparatus it can be hypothesized that Schmidingerothrix is a member of the Gonostomatidae or a close relative. A list of genera (14) and species (58) which have - like Schmidingerothrix - a gonostomatid oral apparatus, as well as a key to these genera are provided.

[Ti] Título:Morphologic and phylogenetic studies of two hypotrichous ciliates, with notes on morphogenesis in Gastrostyla steinii Engelmann, 1862 (Ciliophora, Hypotrichia).

[Ab] Resumo:Two oxytrichid ciliates, Stylonychia (Metastylonychia) nodulinucleata Shi and Li, 1993 and Gastrostyla steinii Engelmann, 1862; collected from Huguangyan Maar Lake and Shenzhen Mangrove Nature Protection Area, southern China, respectively, were investigated using standard methods. The uncommon species Stylonychia (Metastylonychia) nodulinucleata can be recognized by its large body size, the conspicuous caudal cirri in vivo, and a moniliform macronucleus. We provide the first record of the small subunit ribosomal RNA (SSU rRNA) gene sequence for the species. The division of Stylonychia into two subgenera based on morphological and morphogenetic data is supported by the phylogenetic analyses, in which Stylonychia (Metastylonychia) nodulinucleata is placed as a sister branch to the clade including all the sequences of Stylonychia (Stylonychia) mytilus complex. The first brackish water population of Gastrostyla steinii is described in detail, with emphasis on its morphogenesis, which corresponds well with previous populations. In the phylogenetic trees, all the available Gastrostyla sequences, except for Gastrostyla sp. Y2 (KT780432) (probably a misidentification), nest together in the big group of the subfamily Stylonychinae with moderate to high support (ML/BI, 91%/0.95), very likely revealing the monophyly of the genus Gastrostyla.

[Ab] Resumo:Morphology, cirral pattern, and morphogenesis of the new saline soil hypotrich, Gonostomum sinicum nov. spec. collected from Longfeng Wetland in Daqing, north China, were studied, using detailed live observations and protargol-stained specimens. The new species is characterized as follows: (i) a size in vivo of 100-125 × 30-40 µm, (ii) colorless cortical granules, 0.5 µm across, arranged in short rows, (iii) an adoral zone composed of 28-33 membranelles, (iv) three or four frontoventral rows, one of which extends onto the postoral area, (v) left and right marginal rows composed of 18-27 and 21-35, cirri, respectively, and (vi) usually two transverse cirri. Morphogenesis is as usual for the genus Gonostomum, i.e. the cirral primordia II-VI are primary primordia which split into two sets for proter and opisthe in division middle stages, except for anlage I which develops independently. However, the number of frontoventral transverse anlagen is either five or six not only in different individuals but even in proter and opisthe of the same divider. The phylogenetic analyses based on SSU rDNA sequences showed that the genus Gonostomum is nonmonophyletic, indicating that the patterns of cirri and dorsal kineties are homoplasious characters. The new species G. sinicum nov. spec. is perhaps closely related to Cotterillia bromelicola and two congeners.

[Ab] Resumo:The morphology and morphogenesis of two stylonychid ciliates, Stylonychia ammermanniGupta et al., 2001 and Tetmemena bifaria (Stokes, 1887) Berger, 2001, isolated from soil samples of Lombardia region, Northern Italy, and water samples from Cheonggancheon stream, South Korea, were investigated. The Italian population of S. ammermanni was found to be very similar in morphology to the Indian type population and the junior synonym S. harbinensisShi and Ammermann, 2004 since most of the morphometric data overlapped. On the contrary, the Korean population of S. ammermanni showed some non-overlapping differences in ciliature suggesting a separation at subspecies level, i.e., S. ammermanni ammermanni and S. ammermanni koreana nov. subspec. Furthermore, the resting cyst of the Italian population of S. ammermanni has many ring-shaped structures on the surface which, however, were not observed in the Korean population. Phylogenetic analyses based on the SSU rRNA gene sequences show that the Italian and Korean populations of S. ammermanni fit well into the S. mytilus complex and moderately support the subspecies separation. Additionally, we split Tetmemena bifaria into two subspecies, viz., T. bifaria bifaria and T. bifaria minima nov. subspec. based on differences in the number of adoral membranelles and number of cirri in the marginal rows of the Italian and the Argentinian populations in comparison with the populations described by Wirnsberger et al. (1985).

[Ti] Título:Morphology, Ontogeny, and Molecular Phylogeny of Two Freshwater Species of Deviata (Ciliophora, Hypotrichia) from Southern China.

[Ab] Resumo:The morphology and partial morphogenesis of two freshwater hypotrichous ciliates, Deviata brasiliensis Siqueira-Castro et al., 2009 and Deviata rositae Küppers et al., 2007, isolated from southern China, were investigated using live observation and protargol staining. Our populations resemble the original ones in terms of their live characters and ciliary patterns. The main determinable morphogenetic features of D. brasiliensis basically correspond with those of the type population. However, the origin of anlage V for either proter or opisthe is ambiguous: whether anlage V for the proter originates from parental frontoventral row 2 (the same as in the original population) or parental frontoventral row 3 (the same as in Deviata abbrevescens) or even de novo is not clear; the anlage V for the opisthe is possibly derived from frontoventral row 3 and further migrates to frontoventral row 2, like that in D. abbrevescens. In addition, the SSU rRNA gene was first sequenced for both species. Molecular phylogenetic analyses suggest that the genus Deviata is non-monophyletic and has a close relationship with Perisincirra paucicirrata.

[Ab] Resumo:The morphology, ontogenesis, and phylogenetic relationships of a halophile euplotid ciliates, Euplotes qatarensis nov. spec., isolated from the Khor Al-Adaid Lagoon in Qatar were investigated based on live observation as well as protargol- and silver nitrate-impregnated methods. The new species is characterised by a combination of features: the halophile habitat, a cell size of 50-65 × 33-40 µm, seven dorsal ridges, 10 commonly sized frontoventral cirri, two widely spaced marginal cirri, 10 dorsolateral kineties, and a double silverline pattern. The morphogenesis is similar to that of its congeners: (i) the oral primordium develops hypoapokinetally and the parental oral apparatus is retained; (ii) the frontoventral-transverse field of five streaks gives rise to the frontal, ventral, and transverse cirri, but not to the cirri I/1 and the marginal cirri; (iii) the dorsal somatic ciliature develops by intrakinetal proliferation of basal bodies in two anlagen per kinety that are just anterior and posterior to the future division furrow; (iv) the caudal cirri are formed by the two rightmost dorsolateral kineties. The SSU rDNA sequence of E. qatarensis branches with full support in the Euplotopsis elegans-Euplotes nobilii-Euplotopsis raikovi clade. The closest related publicly available SSU rDNA sequence is the one of E. nobilii, with which E. qatarensis has 93.4% sequence similarity. Euplotes parawoodruffi Song & Bradbury, 1997 is transferred to the genus Euplotoides based on the absence of frontoventral cirrus VI/3.

[Ti] Título:High cryptic soil ciliate (Ciliophora, Hypotrichida) diversity in Australia.

[La] Idioma:eng
[Ab] Resumo:The diversity and distribution of soil ciliates from Australia is poorly known. Thus, we studied eight taxa, using the non-flooded Petri dish culture method, live observation, silver impregnation, detailed morphometrics, ontogenesis, and reinvestigation of type slides. At first glance, the Australian taxa looked very similar to described species, however, detailed investigations resulted in the identification of six cryptic species: Afroamphisiella multinucleata minima nov. subspec., Cladotricha similis nov. spec., Erimophrya similis nov. spec., Heterogonostomum salinarum nov. gen., nov. spec., Pseudohemisincirra arabica australiensis nov. subspec., and Pattersoniella (Pattersoniellides) australiensis nov. subgen., nov. spec. This new subgenus is unique among all described hypotrichs in having reduced some anterior paroral dikinetids the fibrillar associates of which are, however, still present. Only two of the eight taxa are possibly cosmopolitans: Apourosomoida halophilaFoissner et al., 2002 and Urosoma karinaeFoissner, 1987. This supports the moderate endemicity model, i.e., that a third of protists have a restricted distribution (Foissner, Chao and Katz 2008).

[Ti] Título:Resting cysts of Parentocirrus hortualis Voß, 1997 (Ciliophora, Hypotrichia), with preliminary notes on encystation and various types of excystation.

[Ab] Resumo:Resting cysts of Parentocirrus hortualis were investigated, using live observation, SEM and TEM. Processes during encystation and excystation were observed in vivo under the light microscope. During encystation, the trophic body becomes globular, the ciliature is resorbed in an anterior direction, the macronuclear nodules fuse into an elongated mass, and finally a cyst wall develops. As typical for oxytrichids, the resting cysts of P. hortualis are of the kinetosome-resorbing type and their wall is made of four layers: ectocyst, mesocyst, endocyst, and metacyst. The beginning of excystation is indicated by the formation of an excystation vacuole that helps the regenerating specimen to break the cyst wall. The excysting specimen leaves the resting cyst in a thin membrane that is gradually resorbed in the outer environment. Also two other excystation modes were observed. During the rare mode, the excystation vacuole breaks the thin membrane instead of the cyst wall that ruptures under the pressure of the body of the regenerating specimen. During the reproduction mode, the regenerating specimen divides within the resting cyst, producing two to four tomites. This is the first report of division in resting cysts of oxytrichids, but reproduction in division cysts was already described in keronopsids.

[Ti] Título:Taxonomy and molecular phylogeny of two novel ciliates, with establishment of a new genus, Pseudogastrostyla n. g. (Ciliophora, Hypotrichia, Oxytrichidae).

[Ab] Resumo:Two novel hypotrichous ciliates, Pseudogastrostyla flava n. g., n. sp. and Urosomoida subtropica n. sp., isolated from Daya Bay Mangrove Park, Huizhou, southern China, were observed in vivo and after protargol staining. Pseudogastrostyla n. g. is diagnosed by having more than 18 frontal-ventral-transverse cirri, an indistinct frontoventral row, undulating membranes in Oxytricha-pattern and dorsomarginal kinety, but lacking dorsal kinety fragmentation during morphogenesis. The monotypic species, P. flava n. sp., is characterized by its brownish body colour, brown-yellowish cortical granules mostly arranged in groups, frontoventral row terminating near mid-body, and one caudal cirrus. Urosomoida subtropica n. sp. can be recognized by having one micronucleus located between two macronuclear nodules, four transverse cirri, pretransverse ventral cirrus (V/2) anteriorly located, four dorsal kineties and three caudal cirri. Phylogenetic analyses based on SSU rRNA gene sequence data indicate that Pseudogastrostyla n. g. is nested within the oxytrichids and is most closely related to Rubrioxytricha ferruginea, and that Urosomoida subtropica n. sp. clusters with Oxytricha elegans rather than the type species, U. agilis. Nodal support values are, however, too low to draw any conclusions about the molecular systematics of the genus Urosomoida.

[Ti] Título:Lithium-induced developmental anomalies in the spirotrich ciliate Stylonychia lemnae (Ciliophora, Hypotrichida).

[Ab] Resumo:Lithium is known to have profound biological effects of varying intensity in different life forms. In the present investigation, the effect of lithium was studied on the spirotrich ciliate Stylonychia lemnae. Lithium treatment brings about quantitative changes in the patterning of ciliary structures in S. lemnae. The dorsal surface of the affected cells develops supernumerary ciliary kineties due to excessive proliferation of the kinetosomes. The ventral surface on the other hand develops fewer than normal cirri formed from reduced numbers of ciliary primordia. The adoral zone of membranelles (AZM) fails to remodel properly as, in certain segments, membranelles become disarranged and misaligned. Lithium-induced changes are transitory as the normal pattern is restored during recovery after the cells are shifted to normal medium, suggesting non-genic regulation of cortical pattern. Lithium also affects the process of cell proliferation as the number of cells undergoing division is negligible as compared to reorganizing cells. The results point to the extremely complex and heterogeneous organization of the cellular cortex (plasma membrane and cytoskeleton) which is capable of exerting autonomous control over the phenotype and cortical pattern.
