Redescriptions of three trachelocercid ciliates (Protista, Ciliophora, Karyorelictea), with notes on their phylogeny based on small subunit rRNA gene sequences Free

Abstract

Three trachelocercid ciliates, (Kovaleva, 1966) Foissner, 1997, (Müller, 1786) Ehrenberg, 1840 and (Wright, 1982) Foissner, 1996, isolated from two coastal habitats at Qingdao, China, were investigated using live observation and silver impregnation methods. Data on their infraciliature and morphology are supplied. The small subunit rRNA (SSU rRNA) genes of and were sequenced for the first time. Phylogenetic analyses based on SSU rRNA gene sequence data indicate that both organisms, and the previously sequenced , are located within the trachelocercid assemblage and that is sister to an unidentified taxon forming a clade that is basal to the core trachelocercids.
