Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 2, Page 141-151, March 2026.
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

Husbandry, General Care, and Transportation of Xenopus laevis and Xenopus tropicalis [PDF]

, 2018
Maintenance of optimal conditions such as water parameters, diet, and feeding is essential to a healthy Xenopus laevis and Xenopus tropicalis colony and thus to the productivity of the lab. Our prior husbandry experience as well as the rapid growth of the National Xenopus Resource has given us a unique insight into identifying and implementing these ...

Introns as Protective Buffers Against Transposable Elements Invasion During Genome Gigantism in a Newt

Genes to Cells, Volume 31, Issue 2, March 2026.
In the giant Pleurodeles waltl genome, introns serve as “structural buffers,” absorbing transposable elements (TEs) to protect coding exons. While this enables “gene body inflation,” persistent TE accumulation eventually leads to transcriptional silencing and functional collapse, or “burst,” of the gene architecture.

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
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.

Xenopus fraseri: Mr. Fraser, where did your frog come from? [PDF]

, 2019
A comprehensive, accurate, and revisable alpha taxonomy is crucial for biodiversity studies, but is challenging when data from reference specimens are difficult to collect or observe.

Comparison of induction during development between Xenopus tropicalis and Xenopus laevis

The International Journal of Developmental Biology, 2006
Several in vitro systems exist for the induction of animal caps using growth factors such as activin. In this paper, we compared the competence of activin-treated animal cap cells dissected from the late blastulae of Xenopus tropicalis and Xenopus laevis.

Expression of ribosomopathy genes during Xenopus tropicalis embryogenesis [PDF]

BMC Developmental Biology, 2016
Because ribosomes are ubiquitously required for protein production, it was long assumed that any inherited defect in ribosome manufacture would be embryonically lethal. However, several human congenital diseases have been found to be associated with mutations in ribosome biogenesis factors.

A Short Report on Melanocyte/Melanoma Culture, Senescence, and Reproducibility

Pigment Cell &Melanoma Research, Volume 39, Issue 2, March 2026.
Culture phenotype is determined by the balance between variable physiology and implemented stability measures, ensuring robust and reproducible pigmentation, proliferation, metabolism, and differentiation data. ABSTRACT At the 2025 ESPCR (European Society for Pigment Cell Research) meeting in Erlangen, a workshop on “Pigment Cell Models: Sensitivity ...
