Comparative Embryonic Spatio-Temporal Expression Profile Map of the Xenopus P2X Receptor Family

open access: yesFrontiers in Cellular Neuroscience, 2019
P2X receptors are ATP-gated cations channels formed by the homo or hetero-trimeric association from the seven cloned subunits (P2X1-7). P2X receptors are widely distributed in different organs and cell types throughout the body including the nervous ...

Limited genomic consequences of hybridization between two African clawed frogs, Xenopus gilli and X. laevis (Anura: Pipidae)

open access: yesScientific Reports, 2017
The Cape platanna, Xenopus gilli, an endangered frog, hybridizes with the African clawed frog, X. laevis, in South Africa. Estimates of the extent of gene flow between these species range from pervasive to rare.

Diversity of parasites from Xenopus laevis (Amphibia: Pipidae) and their seasonal rate of infection in selected habitats in the Limpopo Province, South Africa

open access: yesHelminthologia, 2020
This study determined the diversity and seasonality of parasites species of the African clawed frog, Xenopus laevis (Daudin, 1802), from three localities, namely Modjadjikloof, Mokopane and University of Limpopo, Limpopo Province, South Africa.

Positive Selection of TLR2 and MyD88 Genes Provides Insights Into the Molecular Basis of Immunological Adaptation in Amphibians

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...

Sexy fingers: Pheromones in the glands of male dendrobatid frogs

open access: yesMolecular Ecology, Volume 33, Issue 16, August 2024.
Abstract Many animals exchange chemicals during courtship and mating. In some amphibians, sexual chemical communication is mediated by pheromones produced in male breeding glands that are transferred to the female's nostrils during mating. This has been mostly studied in salamanders, despite frogs having similar glands and courtship behaviours ...

Cloning, characterization, and evolutionary patterns of KCNQ4 genes in anurans

open access: yesEcology and Evolution, Volume 14, Issue 4, April 2024.
In this study, we cloned and obtained the coding regions of a high‐frequency hearing‐related gene (KCNQ4) from 11 representative anuran species and determined the evolutionary patterns of KCNQ4 in anurans. The highly conservation and functional importance of the KCNQ4 genes in anurans were determined and the KCNQ4 genes were under different ...

Evolution of dental tissue mineralization: an analysis of the jawed vertebrate SPARC and SPARC-L families

open access: yesBMC Evolutionary Biology, 2018
Background The molecular bases explaining the diversity of dental tissue mineralization across gnathostomes are still poorly understood. Odontodes, such as teeth and body denticles, are serial structures that develop through deployment of a gene ...

Unleashing diversity through flexibility: The evolutionary journey of sex chromosomes in amphibians and reptiles

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 3, Page 230-241, April 1, 2024.
Sex determination systems have greatly diversified between amphibians and reptiles. In this review, we discuss the diversity of sex chromosomes in amphibians and reptiles resulted from comparative analyses of chromosome homology of sex chromosomes in amphibians and reptiles reported so far, using the genome of the chicken, which is thought to resemble ...

Identifying inconsistencies in exotic pet regulations that perpetuate trade in risky species

open access: yesConservation Biology, Volume 38, Issue 2, April 2024.
Abstract Regulatory inconsistencies at different jurisdictional levels have contributed to the global expansion of the exotic pet trade, with resultant increases in the spread of invasive species and pathogens. Researchers have enumerated multiple limitations and environmental risks posed by international and national rules that govern the exotic pet ...
