Genome evolution in the allotetraploid frog Xenopus laevis

Nature, 2016
To explore the origins and consequences of tetraploidy in the African clawed frog, we sequenced the Xenopus laevis genome and compared it to the related diploid X. tropicalis genome. We characterize the allotetraploid origin of X.

Temporal Relationship of Ocular and Tail Segmental Movements Underlying Locomotor-Induced Gaze Stabilization During Undulatory Swimming in Larval Xenopus

Frontiers in Neural Circuits, 2018
In larval xenopus, locomotor-induced oculomotor behavior produces gaze-stabilizing eye movements to counteract the disruptive effects of tail undulation during swimming.

Development of xenopus resource centers: The national xenopus resource and the european xenopus resource center [PDF]

genesis, 2012
AbstractXenopus is an essential vertebrate model system for biomedical research that has contributed to important discoveries in many disciplines, including cell biology, molecular biology, physiology, developmental biology, and neurobiology. However, unlike other model systems no central repository/stock center for Xenopus had been established until ...

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene-Edited Xenopus Tadpoles. [PDF]

J Pineal Res
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Prevalence of Batrachochytrium dendrobatidis in Xenopus collected in Africa (1871-2000) and in California (2001-2010). [PDF]

PLoS ONE, 2013
International trade of the invasive South African clawed frog (Xenopus laevis), a subclinical carrier of the fungal pathogen Batrachochytrium dendrobatis (Bd) has been proposed as a major means of introduction of Bd into naïve, susceptible amphibian ...

Dusp1 modulates activin/smad2 mediated germ layer specification via FGF signal inhibition in Xenopus embryos

Animal Cells and Systems, 2020
Activin, a member of the transforming growth factor (TGF-β) superfamily, induces mesoderm, endoderm and neuro-ectoderm formation in Xenopus embryos. Despite several previous studies, the complicated gene regulatory network and genes involved in this ...

Reversible Thiol Oxidation Inhibits the Mitochondrial ATP Synthase in Xenopus Laevis Oocytes

Antioxidants, 2020
Oocytes are postulated to repress the proton pumps (e.g., complex IV) and ATP synthase to safeguard mitochondrial DNA homoplasmy by curtailing superoxide production. Whether the ATP synthase is inhibited is, however, unknown.

Mechanisms of tail resorption during anuran metamorphosis

Biomolecular Concepts, 2017
Amphibian metamorphosis has historically attracted a good deal of scientific attention owing to its dramatic nature and easy observability. However, the genetic mechanisms of amphibian metamorphosis have not been thoroughly examined using modern ...

Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

eLife, 2018
In vertebrates, functional motoneurons are defined as differentiated neurons that are connected to a central premotor network and activate peripheral muscle using acetylcholine.
