The mitochondrial genome of Tetrahymena rostrata
Mitochondrial DNA. Part B. Resources, 2020 Tetrahymena rostrata is a ciliated protist which can parasitize the gray field slug, Deroceras reticulatum. Here, we report the sequence of the mitochondrial genome (mt genome) of a strain of T. rostrata that was isolated from the egg of D.

Cells, 2022 Motile cilia and eukaryotic flagella are specific cell protrusions that are conserved from protists to humans. They are supported by a skeleton composed of uniquely organized microtubules—nine peripheral doublets and two central singlets (9 × 2 + 2 ...

Parallel evolution of histophagy in ciliates of the genus
BMC Evolutionary Biology, 2001 Background Species of Tetrahymena were grouped into three complexes based on morphological and life history traits: the pyriformis complex of microstomatous forms; the patula complex of microstome-macrostome transformers; and the rostrata complex of ...

PLoS ONE, 2022 Meiotic DNA double-strand breaks produce reciprocally exchanged DNA strands, which mature into chiasmata that hold homologous chromosomes together as bivalents. These bivalents are subsequently separated in the first meiotic division. In a mutant lacking

A knockout mutation of a constitutive GPCR in Tetrahymena decreases both G-protein activity and chemoattraction. [PDF]
PLoS ONE, 2011 Although G-protein coupled receptors (GPCRs) are a common element in many chemosensory transduction pathways in eukaryotic cells, no GPCR or regulated G-protein activity has yet been shown in any ciliate.

Post-LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor [PDF]
Cytoskeleton (Hoboken)ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Introducing the concept of biocatalysis in the classroom: The conversion of cholesterol to provitamin D 3 [PDF]
, 2016 Biocatalysis is a fundamental concept in biotechnology. The topic integrates knowledge of several disciplines; therefore, it was included in the course “design and optimization of biological systems” which is offered in the biochemistry curricula.

Intraspecies Variation in Tetrahymena rostrata [PDF]
Microorganisms, 2021 Two distinct isolates of the facultative parasite, Tetrahymena rostrata were compared, identifying and utilising markers that are useful for studying clonal variation within the species were identified and utilised. The sequences of mitochondrial genomes and several nuclear genes were determined using Illumina short read sequencing. The two T. rostrata

bioRxiv, 2020 Retinoblastoma-binding proteins 4 and 7 (RBBP4 and RBBP7) are two highly homologous human histone chaperones. They function in epigenetic regulation as subunits of multiple chromatin-related complexes and have been implicated in numerous cancers.

Entry and Killing of
mBio, 2013 Phage-encoded Shiga toxin (Stx) acts as a bacterial defense against the eukaryotic predator Tetrahymena thermophila. It is unknown how Stx enters Tetrahymena protozoa or how it kills them.
