Neon-green fluorescence in the desert gecko Pachydactylus rangei caused by iridophores [PDF]
Scientific Reports, 2021 Biofluorescence is widespread in the natural world, but only recently discovered in terrestrial vertebrates. Here, we report on the discovery of iridophore-based, neon-green flourescence in the gecko Pachydactylus rangei, localised to the skin around the

Semi-automated MicroED system unveils multiple polymorphs in fish-derived guanine crystals. [PDF]
Acta Crystallogr C Struct ChemA semi‐automated MicroED data collection and processing system was established and shown to be suitable for the structural investigation of submicrometer‐scale biogenic crystals.Certain fish display silvery or blue colour, not through pigments, but through specialized guanine crystals that exist within iridophore cells in their skin. Within these cells,

Control Strategies in Guanine Biocrystallization. [PDF]
Angew Chem Int Ed EnglBiological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Pigment pattern morphospace of Danio fishes: evolutionary diversification and mutational effects
Biology Open, 2021 Molecular and cellular mechanisms underlying variation in adult form remain largely unknown. Adult pigment patterns of fishes in the genus Danio, which includes zebrafish, Danio rerio, consist of horizontal stripes, vertical bars, spots and uniform ...

Evolution of Endothelin signaling and diversification of adult pigment pattern in Danio fishes. [PDF]
PLoS Genetics, 2018 Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D.

Beyond the Classics: The Synergy of AI and Genomics Reveals an Expanded Repertoire of Pigmentation Genes. [PDF]
J Exp Zool B Mol Dev EvolClassical approaches for coloration analysis are limited by human low‐resolution phenotyping and genetic analysis. Artificial intelligence allows us to find genes beyond the tip of the iceberg that explain color and pattern diversity in nature. ABSTRACT Pigmentation has long served as a powerful system for exploring gene–trait relationships, yet much ...

Anterior-posterior gene expression differences in three Lake Malawi cichlid fishes with variation in body stripe orientation [PDF]
PeerJ, 2017 Morphological differentiation among closely related species provides opportunities to study mechanisms shaping natural phenotypic variation. Here, we address variation in the orientation of melanin-colored body stripes in three cichlid species of the ...
