First American stand of Paramecium novaurelia and intra-specific differentiation of the species.
نویسندگان
چکیده
A stand of Paramecium novaurelia was found in Boston Massachusetts, USA, the first on this continent. Molecular studies (RAPD and sequencing ofrRNA [3'SSUrRNA-ITS1, 5' LSU rRNA] and COI mtDNA fragments) of P. novaurelia strains show intra-specific polymorphism within the species as strain clusters characterized by variable relationships.

Species of the Paramecium aurelia complex in Russia (western region of European Russia) with molecular characteristics of Paramecium novaurelia.
The presence of P. primaurelia, P. biaurelia, P. triaurelia, and P. novaurelia of the P. aurelia complex was revealed in the studied region of Russia. RAPD-PCR fingerprints (band patterns) of newly identified P. novaurelia strains from Russia were compared to those characteristic for the other chosen European strains of the species. The strains revealed intraspecific polymorphism as several gro...
متن کاملFirst European record of Paramecium septaurelia and the discovery of new European habitats of P. pentaurelia and P. sexaurelia in Russia (Astrakhan and Volgograd regions).
The presence of several species of the P. aurelia complex was revealed in the studied regions. In the Volgograd region P. primaurelia, P. biaurelia, P. triaurelia, and P. novaurelia were recorded. In the Astrakhan Nature Reserve P. primaurelia, P. pentaurelia, P. sexaurelia, and P. septaurelia were identified. Among these species, P. septaurelia was recorded for the first time in Europe, known ...

Annual medics are used for hey production, soil protection, biological fixation of N2 and green manure. In the present study, the inter and intra specific genetic diversity and relatedness of 4 diploid and two tetraploid (M. rugosa and M. scutellata) annual medics were evaluated using microsatellite markers. PCR analysis was performed on genomic DNA from individual plant and PCR products were d...

متن کاملNew 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...
