Tritium-Induced Effects in Paramecium Aurelia
Experimental Biology and Medicine, 1951 Summary and ConclusionsEffects induced by metabolized radioactive hydrogen (tritium or T) and presumed to be genetic in nature have been measured in Paramecium aurelia. Organisms were allowed to divide 6 to 8 times during 2 days in culture fluid containing T in concentrations varying from 1 to 100 mc per ml. With increasing radioactivity of the medium,

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]
, 2007 Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon ...

PLoS Genetics, 2020 Gene duplication and diversification drive the emergence of novel functions during evolution. Because of whole genome duplications, ciliates from the Paramecium aurelia group constitute a remarkable system to study the evolutionary fate of duplicated ...

A fragmented metazoan organellar genome [PDF]
, 2008 Background: Animal mitochondrial (mt) genomes are characteristically circular molecules of ~16–20 kb. Medusozoa (Cnidaria excluding Anthozoa) are exceptional in that their mt genomes are linear and sometimes subdivided into two to presumably four ...

Folia Biologica, 2018 Knowledge about the occurrence and distribution of species from the Paramecium aurelia complex is important for understanding their evolution. However, sampling of paramecia in the southern hemisphere, and, in general, in the tropics was usually done ...

BMC Genomics, 2011 Background Despite the fact that the organization of the ciliate mitochondrial genome is exceptional, only few ciliate mitochondrial genomes have been sequenced until today. All ciliate mitochondrial genomes are linear.

Animals and Fungi are Each Other's Closest Relatives: Congruent Evidence from Multiple Proteins [PDF]
, 1993 Phylogenetic relationships among plants, animals, and fungi were examined by using sequences from 25 proteins. Four insertions/deletions were found that are shared by two of the three taxonomic groups in question, and all four are uniquely shared by ...

, 1951 The field under review is growing so rapidly that it is impossible to cover more than a sampling of recent papers in the allotted space. Important subjects such as the genetics and chemistry of viruses and certain topics in bacterial genetics have had ...

Spliced DNA sequences in the Paramecium germline: their properties and evolutionary potential
, 2014 Despite playing a crucial role in germline-soma differentiation, the evolutionary significance of developmentally regulated genome rearrangements (DRGRs) has received scant attention. An example of DRGR is DNA splicing, a process that removes segments of
