Molecular studies on intraspecific differentiation of Paramecium dodecaurelia, with description of new stands of the species (Protozoa, Ciliophora).

چکیده
New stands of Paramecium dodecaurelia were found in Russia, Ukraine, Kazahstan, Poland, and Tenerife. Molecular studies (RAPD and sequencing of LSU rRNA and CO1 mtDNA gene fragments) of P. dodecaurelia strains depicted intraspecific polymorphism within the species, revealed as distinct differences between strains from the USA in comparison with strains from different regions of the Palearctic.

New stands of species of the Paramecium aurelia complex (Ciliophora, Protozoa) in Europe and South America (Ecuador).
The occurrence of species of the P. aurelia complex has been studied at a large scale in Europe and the majority of known species of the complex have been found there. However, a different number of habitats were studied in particular zones of Europe, the greatest number in the central zone. Herein new stands of several species of the Paramecium aurelia complex are presented from Europe includi...
متن کاملNew, world-wide data on the distribution of species of the Paramecium aurelia complex (Ciliophora, Protozoa).
This is the first report on the presence of P. biaurelia in Tasmania, an island that has probably never been investigated before for the occurrence of the P. aurelia species. P. tetraurelia was recorded in Brazil, another very poorly investigated country in terms of this species complex. New stands of P. biaurelia and P. tetraurelia were also recorded in Japan. We present data concerning the oc...
متن کاملNew stands of species of the Paramecium aurelia complex in Africa and Europe.
The relevance of geographical distribution and the roles of dispersal and spatial isolation during the speciation of microorganisms are nowadays of great interest. The Paramecium aurelia species complex is a perfect model system to explore these questions given its long history as a study subject and broad distribution. However, the world-wide distribution of the Paramecium aurelia complex (Cil...
متن کاملPolymorphism within Paramecium sexaurelia (Ciliophora, Oligohymenophorea) and description of a new stand of the species in China.
The presence of Paramecium sexaurelia from the Paramecium aurelia complex was recorded for the first time in China (Beijing). RAPD fingerprints (band patterns) of P. sexaurelia strains, the new strain from China and others from Asia, as well as from Europe and Puerto Rico, showed polymorphism within the species as several groups of genotypes characterized by different band patterns.
متن کاملParamecium sexaurelia--intra-specific polymorphism and relationships with other Paramecium aurelia spp., revealed by cytochrome b sequence data.
Genetic distances among strains of P. sexaurelia were compared by sequencing the mitochondrial cytochrome b gene. The relationships of P. sexaurelia with representative strains of other species of the P. aurelia complex and related species, i.e., P. schewiakoffi, P. jenningsi and P. multimicronucleatum were evaluated. All investigated P. sexaurelia and P. dodecaurelia strains grouped together w...
