Basonuclin-2 requirements for zebrafish adult pigment pattern development and female fertility.

PLoS Genetics, 2009
Relatively little is known about the generation of adult form. One complex adult trait that is particularly amenable to genetic and experimental analysis is the zebrafish pigment pattern, which undergoes extensive remodeling during post-embryonic ...

Incidence of the thermal transition in the range of 45-5°C in chromatophores present in the wings of Schistocerca americana [version 1; peer review: 1 approved, 2 approved with reservations]

F1000Research, 2019
The variation of the color intensity of the chromatophores present in the wings of Schistocerca americana was analyzed by exposing 31 specimens to thermal transitions within the range of 45 - 5 °C.

Protein translocons in photosynthetic organelles of Paulinella chromatophora

Acta Societatis Botanicorum Poloniae, 2014
The rhizarian amoeba Paulinella chromatophora harbors two photosynthetic cyanobacterial endosymbionts (chromatophores), acquired independently of primary plastids of glaucophytes, red algae and green plants.

THE CHARACTER OF CHROMATOPHORES. [PDF]

JAMA: The Journal of the American Medical Association, 1904
In regard to the origin of the cell masses characteristic of pigmented moles and in regard to the origin of the melanotic tumors of the skin, different views are still held. A number of pathologists believe in the epithelial origin of nevi and of melanotic tumors; others assume a mesodermal origin.

Cases of albinism and leucism in amphibians in Italy: new reports

Natural History Sciences, 2017
Findings of abnormally pigmented amphibian individuals provide interesting insights on intraspecific phenotypic variability as well as on variation among populations inhabiting different habitats.

Possible involvement of cone opsins in distinct photoresponses of intrinsically photosensitive dermal chromatophores in tilapia Oreochromis niloticus. [PDF]

PLoS ONE, 2013
Dermal specialized pigment cells (chromatophores) are thought to be one type of extraretinal photoreceptors responsible for a wide variety of sensory tasks, including adjusting body coloration.

Developmental and Cellular Basis of Vertical Bar Color Patterns in the East African Cichlid Fish Haplochromis latifasciatus

Frontiers in Cell and Developmental Biology, 2020
The East African adaptive radiations of cichlid fishes are renowned for their diversity in coloration. Yet, the developmental basis of pigment pattern formation remains largely unknown.

Teleost Fish-Specific Preferential Retention of Pigmentation Gene-Containing Families After Whole Genome Duplications in Vertebrates

G3: Genes, Genomes, Genetics, 2018
Vertebrate pigmentation is a highly diverse trait mainly determined by neural crest cell derivatives. It has been suggested that two rounds (1R/2R) of whole-genome duplications (WGDs) at the basis of vertebrates allowed changes in gene regulation ...

On the role of TFEC in reptilian coloration

Frontiers in Cell and Developmental Biology
Reptilian species, particularly snakes and lizards, are emerging models of animal coloration. Here, I focus on the role of the TFEC transcription factor in snake and lizard coloration based on a study on wild-type and piebald ball pythons.

Improvement of Bioactive Compound Classification through Integration of Orthogonal Cell-Based Biosensing Methods

Sensors, 2007
Lack of specificity for different classes of chemical and biological agents, and false positives and negatives, can limit the range of applications for cell-based biosensors.
