Abstract Microorganisms play important roles in the biogeochemical cycling of sulphur (S), an essential element Earth's biosphere. Shotgun metagenome sequencing has opened a new avenue to advance our understanding S microbial communities. However, accurate metagenomic profiling communities remains technically challenging, mainly due low coverage and inaccurate definition gene families public orthology databases. Here we developed manually curated database (SCycDB) profile functional genes...

The morphology and small subunit ribosomal RNA (SSU rRNA) gene sequences of three new species ciliates in the genus Strombidium are recorded: S. paracapitatum sp. nov., cuneiforme caudispina nov. is characterized by having a prominent transparent apical protrusion two types extrusomes. differs from its congeners combination long conical body shape, eyespot elongated tail. recognized posterior spine short ventral kinety. In SSU rRNA trees, all members cluster into separate groups. first group...
Oligotrich ciliates are important components of marine microplankton and have a high biodiversity. In the present paper, morphology small subunit rRNA (SSrRNA) gene sequence four Strombidium species recorded, including new species, S. pseudostylifer sp. nov. that was sampled from mangrove wetland. This is characterized by its prominent apical protrusion, long constant tail large number ventral dikinetids. addition, two poorly known chlorophilum Montagnes et al., 1988 Lynn, D. H., &...
Three oligotrich ciliates, Apostrombidium parakielum spec. nov., Novistrombidium apsheronicum (Alekperov & Asadullayeva, 1997) Agatha, 2003 and testaceum (Anigstein, 1914) Song Bradbury, 1998 were collected from the coastal waters of China their morphology small-subunit rRNA (SSU rRNA) gene sequences studied. The novel species can be recognized by combination its obconical body shape, 14-16 anterior 6-8 ventral membranelles, somatic kinety in three parts conspicuously long dorsal cilia....
A tintinnid ciliate isolated from waters of the Thames River (Connecticut, USA) is described through combined in vivo observation, protargol impregnation, and phylogenetic analysis. The novel genus Dartintinnus its type species, D. alderae are distinct established taxa by a lorica that collapses on both anterior posterior ends. placed family Eutintinnidae based hyaline, elongated opened at ends, ciliary pattern including ventral kinety, least one dorsal right, left lateral fields, sister...
A population of Kiitricha minuta Xu et al., 2008 , a small kiitrichid ciliate, was isolated from brackish water sample in Jiaozhou Bay, Qingdao, northern China. After comparison its morphology and infraciliature, it is believed that this morphotype should be assigned to the genus Caryotricha; hence, new combination suggested, Caryotricha ( ) nov. comb. The small-subunit (SSU) rRNA gene sequence determined order elucidate phylogenetic position poorly known, ambiguous genus. organism can...
Microscopic methods were used to investigate the morphological characterization of two novel oligotrich ciliates, Spirostrombidium paraurceolare sp. nov. and faurefremieti nov., isolated from a mangrove wetland in Zhanjiang an intertidal sandy beach Qingdao, respectively. is characterized by three thigmotactic 8–10 buccal membranelles, girdle kinety spiralling around cell with one half whorls, located at right anterior third dorsal side anteriorly. can be recognized prominently deep broad...
The morphology and phylogeny of four oligotrichid ciliates, Parallelostrombidium paraellipticum sp. n., P. dragescoi jankowskii (Xu et al. 2009) comb. kahli are described or redescribed based on live observation, protargol stained material, SSU rRNA gene sequences. new species n. is characterized by its obovoidal cell shape, adoral zone composed 17-21 collar, 9-11 buccal, two thigmotactic membranelles, extrusomes attached in one row along the girdle kinety. distinguished from congeners shape...
Two poorly known tintinnine ciliates collected from the coastal waters of PR China, viz., Codonellopsis mobilis Wang, 1936 and Tintinnopsis chinglanensis Nie & Ch'eng, 1947, were redescribed neotypified using live observation, protargol staining SSU rRNA gene sequencing. Ciliature information sequence data both species revealed for first time improved diagnoses given based on original descriptions present study. Further phylogenetic analyses inferred sequences morphological suggested that...
Abstract Background The taxonomy of tintinnine ciliates is vastly unresolved because it has traditionally been based on the lorica (a secreted shell) and only recently incorporated cytological molecular information. Tintinnopsis, most speciose genus, also problematic: known to be non-monophyletic, but cannot revised until more its species are studied with modern methods. Results Here, T. hemispiralis Yin, 1956, kiaochowensis uruguayensis Balech, 1948, from coastal waters China, were studied....
Abstract We have developed a novel STR 25‐plex florescence multiplex‐STR kit (DNATyper25) to genotype 23 autosomal and two sex‐linked loci for forensic applications paternity analysis. Of the loci, 20 are non‐CODIS. The markers include Y‐STR locus (DYS391) Amelogenin gene. present developmental validation studies show that DNATyper25 is reproducible, accurate, sensitive, robust. Sensitivity testing showed full profiles were achieved with as low 125 pg of human DNA. Specificity demonstrated...
Strombidiids are common free-living ciliates that have colonized coastal and open oceanic waters across the world. In recent years, numerous new taxa gene sequences of strombidiids been reported, revealing a large diversity both their morphologic genetic features. Here, we compare taxonomic characters all genera in family Strombidiidae, provide key to identification, investigate molecular phylogeny. addition, analyze regional distribution based on faunal data accumulated China attempt infer...
Morphology of Three Aloricate Choreotrich ciliates, Including Description a New Species Parastrombidinopsis costalis sp. n. (Ciliophora, Choreotrichia), and phylogeny the genus
The morphology of two oligotrich ciliates, Pelagostrombidium fallax (Zacharias, 1895) Krainer, 1991 and Limnostrombidium viride (Stein, 1867) 1995, collected from a freshwater pond in northern China, was studied based on live observation protargol staining. Currently, undescribed features the girdle kinety P. are (a) sparsely spaced single argyrophilic basal bodies shoulder region (b) U-shape formed below buccal peristome. An improved diagnosis for is supplied, previous present morphological...
Abstract Ciliophora are one of the most diverse phyla unicellular eukaryotes. Members this group widely distributed and have been found in several environments including those that anaerobic. However, paucity sufficient omics data for major classes phylum Ciliophora, especially anaerobic ciliate lineages, has a serious impediment to research thus far. In study, were expanded include representatives 16 (excluding Cariacotrichea Copemetopea) using single‐cell sequencing techniques. Using 57...
Abstract Psammophillic ciliates are an integral part of the foodweb despite being underrepresented in terms molecular phylogeny and modern taxonomy. To investigate karyorelictean group, sampling was conducted interstitial marine habitats China for living between sand grains, resulting examination families Cryptopharyngidae Jankowski, 1980 Kentrophoridae 1980. Three species, i.e., Cryptopharynx setigerus Kahl, 1928, Kentrophoros fasciolatus (Sauerbrey, 1928) Foissner, 1995 K. fistulosus...
