Morphology, morphogenesis and molecular phylogeny of Lamtostyla granulifera sinensis subsp. nov. (Ciliophora, Hypotrichia) from a wetland in China
The morphology, morphogenesis and molecular phylogeny of a hypotrichous ciliate, Lamtostyla granulifera sinensis subsp. nov., isolated from northern China, were investigated. This population appeared highly similar in morphology to L. granulifera Foissner, 1997. However, on detailed investigation some non-overlapping features were identified, i.e., the body shape and the arrangement of the cortical granules. These differences suggested the separation at subspecies level. Furthermore, the morphogenesis of the new subspecies is described, which is characterized by: (1) the posterior part of the parental adoral zone of membranelles is renewed; (2) the amphisiellid median cirral row is formed from two anlagen; and (3) the frontoventral-transverse cirral anlagen II to VI generate one transverse cirrus each. Phylogenetic analyses based on SSU rDNA sequence data show that Lamtostyla species are scattered in different clades. The monophyly of the genus Lamtostyla is also rejected by the AU test in this study.
期刊介绍:
Articles deal with protists, unicellular organisms encountered free-living in various habitats or as parasites or used in basic research or applications. The European Journal of Protistology covers topics such as the structure and systematics of protists, their development, ecology, molecular biology and physiology. Beside publishing original articles the journal offers a forum for announcing scientific meetings. Reviews of recently published books are included as well. With its diversity of topics, the European Journal of Protistology is an essential source of information for every active protistologist and for biologists of various fields.
