Evolution &Development, Volume 27, Issue 1, March 2025.Hybrid Danionin embryos undergo normal developmental transitions until 1‐day postfertilization (dpf), where inter‐genera hybrids exhibit gastrulation defects. Despite juvenile growth variability hybrids reach adulthood, with males showing reduced fertility and abnormal sperm morphology. Only D. rerio x D.

Gene overexpression in P. tetraurelia Gene overexpression can be achieved by introducing more copies of the target gene into the MAC in P. tetraurelia (Table 1). A small portion of exogenous DNA introduced into the MAC of P. tetraurelia can be integrated into the chromosomes, similar to Tetrahymena, while most is added with Paramecium telomerelike ...

ParTIES: a toolbox for Paramecium interspersed DNA elimination studies
Bioinform., 2016 MOTIVATION Developmental DNA elimination occurs in a wide variety of multicellular organisms, but ciliates are the only single-celled eukaryotes in which this phenomenon has been reported.

Metabolism of saturated fatty acids by Paramecium tetraurelia.
Journal of Lipid Research, 1987 Paramecium requires oleate for growth. The phospholipids of the ciliate contain high concentrations of palmitate and 18- and 20-carbon unsaturated fatty acids. We previously showed that radiolabeled oleate is desaturated and elongated to provide these 18-

Comparative Genomic Analysis of Holospora spp., Intranuclear Symbionts of Paramecia
Frontiers in Microbiology, 2018 While most endosymbiotic bacteria are transmitted only vertically, Holospora spp., an alphaproteobacterium from the Rickettsiales order, can desert its host and invade a new one.

Metachronal waves in a chain of rowers with hydrodynamic interactions [PDF]
, 2010 Filaments on the surface of a microorganism such as Paramecium or Ophalina beat highly synchronized and form so-called metachronal waves that travel along the surfaces.

Centrin diversity and basal body patterning across evolution: new insights from Paramecium
Biology Open, 2017 First discovered in unicellular eukaryotes, centrins play crucial roles in basal body duplication and anchoring mechanisms. While the evolutionary status of the founding members of the family, Centrin2/Vfl2 and Centrin3/cdc31 has long been investigated ...

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier
Biological Reviews, Volume 100, Issue 1, Page 227-244, February 2025.ABSTRACT Glaciers host a variety of cold‐adapted taxa, many of which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning of glacier ecosystems, particularly in light of current glacier retreat.

Warming During Different Life Stages has Distinct Impacts on Host Resistance Ecology and Evolution
Ecology Letters, Volume 28, Issue 2, February 2025.Investigating whether animals can adapt to infection with rising temperatures is important for forecasting their persistence under climate change. Using a nematode host–bacterial pathogen system, our study shows that prolonged warming selects for resistance. The evolutionary dynamics of resistance depended on the balance among pathogen virulence, costs

Paramecium tetraurelia basal body structure
Cilia, 2016 Paramecium is a free-living unicellular organism, easy to cultivate, featuring ca. 4000 motile cilia emanating from longitudinal rows of basal bodies anchored in the plasma membrane.
