Pigments, Patterns, and Fish Behavior [PDF]
Zebrafish, 2008 Color patterns in fish are often multicomponent signals, composed of pigment-based and structural color patches that can be used to communicate within species, in both inter- and intrasexual interactions, and between species. In this review, we discuss some of the roles played by pigment-based elements of color pattern.

Frontiers in Ecology and Evolution, 2020 In order to understand molecular and genetic mechanism of color pattern formation, not only adult phenotypes but also processes and mechanisms of color production and pattern formation during embryonic and postembryonic stages should be described.

Multiple pigment cell types contribute to the black, blue, and orange ornaments of male guppies (Poecilia reticulata). [PDF]
PLoS ONE, 2014 The fitness of male guppies (Poecilia reticulata) highly depends on the size and number of their black, blue, and orange ornaments. Recently, progress has been made regarding the genetic mechanisms underlying male guppy pigment pattern formation, but we ...

How Much Pigment Should Flowers Have? Flowers With Moderate Pigmentation Have Highest Color Contrast
Frontiers in Ecology and Evolution, 2021 Floral pigments are a core component of flower colors, but how much pigment a flower should have to yield a strong visual signal to pollinators is unknown.

Eco-Evo-Devo of petal pigmentation patterning [PDF]
Essays in Biochemistry, 2022 Abstract Colourful spots, stripes and rings decorate the corolla of most flowering plants and fulfil important biotic and abiotic functions. Spatial differences in the pigmentation of epidermal cells can create these patterns. The last few years have yielded new data that have started to illuminate the mechanisms controlling the function,

Endothelin receptor Aa regulates proliferation and differentiation of Erb-dependent pigment progenitors in zebrafish. [PDF]
PLoS Genetics, 2019 Skin pigment patterns are important, being under strong selection for multiple roles including camouflage and UV protection. Pigment cells underlying these patterns form from adult pigment stem cells (APSCs).

Pigment pattern in jaguar/obelix zebrafish is caused by a Kir7.1 mutation: implications for the regulation of melanosome movement. [PDF]
PLoS Genetics, 2006 Many animals have a variety of pigment patterns, even within a species, and these patterns may be one of the driving forces of speciation. Recent molecular genetic studies on zebrafish have revealed that interaction among pigment cells plays a key role ...

Pigmented melanoma cell migration study on murine syngeneic B16F10 melanoma cells or tissue transplantation models [PDF]
, 2019 Melanoma is a lethal form of skin cancer with poor prognosis, especially due to the early metastatic feature. Recent studies have shown that the melanin pigment influences the nanomechanical properties and, therefore, the metastatic behavior of the ...

Advancing biology through a deeper understanding of zebrafish ecology and evolution
eLife, 2015 Over the last two decades, the zebrafish has joined the ranks of premier model organisms for biomedical research, with a full suite of tools and genomic resources. Yet we still know comparatively little about its natural history.
