It's not easy being green: Comparing typical skin colouration among amphibians with colour abnormalities associated with chromatophore deficits [PDF]

open access: yesEcology and Evolution
Amphibians can obtain their colour from a combination of several different pigment and light reflecting cell types called chromatophores, with defects in one or several of the cells leading to colour abnormalities. There is a need for better recording of

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny [PDF]

open access: yesFrontiers in Cell and Developmental Biology
In animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...

Cellular and Molecular Basis of Environment-Induced Color Change in a Tree Frog [PDF]

open access: yesAnimals
Background color matching is essential for camouflage and thermoregulation in ectothermic vertebrates, yet several key cellular-level questions remain unresolved.

A Simple Method for RNA-Seq of Manually Isolated Chromatophores in Oryzias Fishes. [PDF]

open access: yesDev Growth Differ
ABSTRACT RNA sequencing (RNA‐seq) has become an essential tool for analyzing gene expression and exploring cell type–specific transcriptomes. However, sample preparation and quality control remain challenging, as current approaches typically rely on dissecting tissues containing mixed cell populations or using flow cytometry to isolate fluorescently ...

Quantifying the Speed of Chromatophore Activity at the Single-Organ Level in Response to a Visual Startle Stimulus in Living, Intact Squid

open access: yesFrontiers in Physiology, 2021
The speed of adaptive body patterning in coleoid cephalopods is unmatched in the natural world. While the literature frequently reports their remarkable ability to change coloration significantly faster than other species, there is limited research on ...

FOF1-ATPase Motor-Embedded Chromatophore as Drug Delivery System: Extraction, Cargo Loading Ability and Mucus Penetration Ability

open access: yesPharmaceutics, 2023
Mucosal drug delivery permits direct and prompt drug absorption, which is capable of reducing undesirable decomposition that occurs before absorption.

Zebrafish endzone regulates neural crest-derived chromatophore differentiation and morphology. [PDF]

open access: yesPLoS ONE, 2008
The development of neural crest-derived pigment cells has been studied extensively as a model for cellular differentiation, disease and environmental adaptation.

Loss of key endosymbiont genes may facilitate early host control of the chromatophore in Paulinella

open access: yesiScience, 2022
Summary: The primary plastid endosymbiosis (∼124 Mya) that occurred in the heterotrophic amoeba lineage, Paulinella, is at an earlier stage of evolution than in Archaeplastida, and provides an excellent model for studying organelle integration.

The Puzzle of Metabolite Exchange and Identification of Putative Octotrico Peptide Repeat Expression Regulators in the Nascent Photosynthetic Organelles of Paulinella chromatophora

open access: yesFrontiers in Microbiology, 2020
The endosymbiotic acquisition of mitochondria and plastids more than one billion years ago was central for the evolution of eukaryotic life. However, owing to their ancient origin, these organelles provide only limited insights into the initial stages of

The extent of rapid colour change in male agamid lizards is unrelated to overall sexual dichromatism

open access: yesEcology and Evolution, 2023
Dynamic colour change is widespread in ectothermic animals, but has primarily been studied in the context of background matching. For most species, we lack quantitative data on the extent of colour change across different contexts.
