The mitochondrial genome sequence of the ciliate Paramecium caudatum reveals a shift in nucleotide composition and codon usage within the genus Paramecium

open access: yesBMC 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.

Modulation of a sustained calcium current by intracellular pH in horizontal cells of fish retina. [PDF]

open access: yes, 1993
A sustained high voltage-activated (HVA), nifedipine- and cadmium-sensitive calcium current and a sustained calcium action potential (AP) were recorded from horizontal cells isolated from catfish retina.

The mitochondrial genomes of the ciliates Euplotes minuta and Euplotes crassus

open access: yesBMC Genomics, 2009
Background There are thousands of very diverse ciliate species from which only a handful mitochondrial genomes have been studied so far. These genomes are rather similar because the ciliates analysed (Tetrahymena spp.

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]

open access: yes, 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 ...

Paramecium swimming and ciliary beating patterns: a study on four RNA interference mutations.

open access: yesIntegrative Biology, 2015
Paramecium cells swim and feed by beating their thousands of cilia in coordinated patterns. The organization of these patterns and its relationship with cell motility has been the subject of a large body of work, particularly as a model for ciliary ...

Novel Insights into the Development and Function of Cilia Using the Advantages of the Paramecium Cell and Its Many Cilia

open access: yesCells, 2015
Paramecium species, especially P. tetraurelia and caudatum, are model organisms for modern research into the form and function of cilia. In this review, we focus on the ciliary ion channels and other transmembrane proteins that control the beat frequency

Study on the role of microtubules related to the nuclear behaviors during conjugation of paramecium caudatum [PDF]

open access: yes, 2002
In most organisms, microtubules are involved in the migration of the pronuclei during fertilization. Fertilization process of Paramecium caudatum includes two stages of nuclear migration. One is a selection of meiotic products.
