Our populations resemble the original one in terms of their live characters and cirral pattern. The main events during binary fission are as follows: (1) the parental adoral zone of membranelles is retained completely by the proter; (2) both in the proter and in the opisthe five frontal-ventral cirral anlagen are recognizable; (3) the marginal rows and dorsal kineties develop intrakinetally. In addition, the SSU rRNA gene was sequenced for the genus Parakahliella for the first time. Molecular phylogenetic analyses suggest that two populations of the genus Parakahliella cluster together and have a close relationship with species of Oxytrichidae.  VL - 2018 IS - Volume 57, Issue 2 PY - 2018 SN - 0065-1583 C1 - 1689-0027 SP - 107 EP - 122 DO - 10.4467/16890027AP.18.010.8984 UR - https://ejournals.eu/en/journal/acta-protozoologica/article/integrative-studies-on-the-morphology-morphogenesis-and-molecular-phylogeny-of-a-soil-ciliate-parakahliella-macrostoma-foissner-1982-berger-et-al-1985-ciliophora-hypotrichia KW - Hypotrichs KW - Kahliellidae KW - ontogenesis KW - SSU rRNA KW - taxonomy
