Genetic mapping and molecular mechanism behind color variation in the Asian vine snake

open access: yesGenome Biology, 2023
Background Reptiles exhibit a wide variety of skin colors, which serve essential roles in survival and reproduction. However, the molecular basis of these conspicuous colors remains unresolved.

Morphological Characteristics and Comparative Transcriptome Analysis of Three Different Phenotypes of Pristella maxillaris

open access: yesFrontiers in Genetics, 2019
Pristella maxillaris is known as the X-ray fish based on its translucent body. However, the morphological characteristics and the molecular regulatory mechanisms of these translucent bodies are still unknown. In this study, the following three phenotypes,

Body coloration and mechanisms of colour production in Archelosauria: the case of deirocheline turtles [PDF]

open access: yesRoyal Society Open Science, 2019
Animal body coloration is a complex trait resulting from the interplay of multiple mechanisms. While many studies address the functions of animal coloration, the mechanisms of colour production still remain unknown in most taxa.

A new Andean treefrog (Amphibia: Hyloscirtus bogotensis group) from Ecuador: an example of community involvement for conservation [PDF]

open access: yesPeerJ, 2021
We provide several lines of evidence to delimit a new species of Hyloscirtus and define its phylogenetic position inside the Hyloscirtus bogotensis group.

Ultrastructure and regulation of color change in blue spots of leopard coral trout Plectropomus leopardus

open access: yesFrontiers in Endocrinology, 2022
The leopard coral trout generally exhibited numerous round, minute blue spots covering its head (about the size of nostril) and body (except ventral side). This is a characteristic that distinguishes them from similar species. Recently, however, we found

Tight Junction Protein 1a regulates pigment cell organisation during zebrafish colour patterning

open access: yeseLife, 2015
Zebrafish display a prominent pattern of alternating dark and light stripes generated by the precise positioning of pigment cells in the skin. This arrangement is the result of coordinated cell movements, cell shape changes, and the organisation of ...

A Recessive oca2 Mutation Underlies Albinism in Xiphophorus Fish. [PDF]

open access: yesPigment Cell Melanoma Res
Genetic mapping of albino Xiphophorus hellerii showed that albinism is associated with a recessive oca2 variant. This variant leads to early termination of the Oca2 protein. This study identifies a novel model system to investigate conserved mechanisms of pigmentation biology.

Ultrastructure of the dermal chromatophores in the Fringe-toed lizard, Acanthodactylus orientalis

open access: yesZoologia (Curitiba), 2017
Histology and electron microscopic studies of the dorsal skin of the Fringe-toed lizard, Acanthodactylus orientalis Angel, 1936, showed three types of dermal chromatophores: xanthophores, iridophores and melanophores. These pigment cells were observed in

Morphological and molecular characterization of dietary-induced pseudo-albinism during post-embryonic development of Solea senegalensis (Kaup, 1858). [PDF]

open access: yesPLoS ONE, 2013
The appearance of the pseudo-albino phenotype was investigated in developing Senegalese sole (Solea senegalensis, Kaup 1858) larvae at morphological and molecular levels.
