“…Several genes, stress enzymes, growth hormones, reproductive hormones etc may influence skin colour and hue fixing. MCH (skin lightening), MSH (skin darkening), somatostatin, melanocortin, melanin, catecholamine (adrenaline and noradrenaline, dopamine cortisol) etc are some of the important regulators of the body pigmentation (Choi et al ., 2020; Kasukawa et al ., 1987; Logan et al ., 2006; Vissio et al ., 2021; Wang et al ., 2020; Yang et al ., 2021). A physiological colour change signifies a rapid alteration in skin colour and shade, manifested as pigment aggregation or dispersion within stellate‐shaped chromatophores (Fujii, 2000).…”

Some freshwater teleost fish have pigment cells whose arrangement and shape are affected by the environment. Natural light has a wide range of light intensity. Fish are sensitive to the background and exposed light colour. Fish body colour is a significant criterion in fixing its market value, whether it is ornamental or edible. By favourable light exposure, a culturist may get a good market value of fish on most ethical grounds. In this study, we recorded the changes in melanophore response with the changes in light colour on Channa punctata. Adult fish were treated with monochromatic lights (darkness, white, blue and red light) for 5 and 28 days. After treatment, their body colour and melanophore size, number, length and the number of dendrites were studied. The results showed a significant influence of monochromatic light on melanophore arrangement in fish skin. The data showed that blue light is appropriate for the overall species colour of photic C. punctata. Continuous black or white light caused severe damage to the fish's appearance.

“…The IL-17 signaling pathway (oas04657) regulates the production and action of IL-17, which can inhibit melanin production [135]. Purine metabolism (oas00230) may be associated with golden pigment production [136][137][138], which correlates with the blue phenotype [139], and may also affect melanin synthesis [140][141][142]. Glycine, serine, and threonine metabolism (oas00260) also correlate with the blue phenotype [139,143].…”

Wool color is controlled by a variety of genes. Although the gene regulation of some wool colors has been studied in relative depth, there may still be unknown genetic variants and control genes for some colors or different breeds of wool that need to be identified and recognized by whole genome resequencing. Therefore, we used whole genome resequencing data to compare and analyze sheep populations of different breeds by population differentiation index and nucleotide diversity ratios (Fst and θπ ratio) as well as extended haplotype purity between populations (XP-EHH) to reveal selection signals related to wool coloration in sheep. Screening in the non-white wool color group (G1 vs. G2) yielded 365 candidate genes, among which PDE4B, GMDS, GATA1, RCOR1, MAPK4, SLC36A1, and PPP3CA were associated with the formation of non-white wool; an enrichment analysis of the candidate genes yielded 21 significant GO terms and 49 significant KEGG pathways (p < 0.05), among which 17 GO terms and 21 KEGG pathways were associated with the formation of non-white wool. Screening in the white wool color group (G2 vs. G1) yielded 214 candidate genes, including ABCD4, VSX2, ITCH, NNT, POLA1, IGF1R, HOXA10, and DAO, which were associated with the formation of white wool; an enrichment analysis of the candidate genes revealed 9 significant GO-enriched pathways and 19 significant KEGG pathways (p < 0.05), including 5 GO terms and 12 KEGG pathways associated with the formation of white wool. In addition to furthering our understanding of wool color genetics, this research is important for breeding purposes.

“…Somehow, the underlying mechanisms of the cutaneous growth and pigmentation of the red discus at different developmental stages has yet to be studied. Even though the metabolomics analysis [25] revealed speci c chromophores on the blue, yellow and white pigmentation of discus, no data of red discus was reported.…”

This is the first report to describe the differential growth of cutaneous pigments and the molecular processes involved in two red discus (Symphysodon spp.), Red Melon and Red Cover, with different tones of red pigmentation develop from juveniles to adults. Microscopic observation detected xanthophores in all samples, erythrophores in both adult groups and Red Melon juveniles, while melanophores were only found in Red Cover. The skin transcriptome analysis revealed extracellular matrix (ECM) activities and collagen metabolic genes were elevated in both juveniles, as compared to the adults. The development of erythrophores and xanthophores in the Red Melon juveniles were regulated by genes involved in the pteridine synthesis, one-carbon metabolism, and lipid metabolism. Temporal inhibition of melanophore development in Red Melon juveniles might be attributed to the active expression of Wnt-signalling inhibitor genes, sost and notum2. Melanosome transport in Red Cover was likely relied on microtubules and the spectrin-associated cytoskeleton. Tyrosinase late N-glycan processing and its transport from Golgi apparatus into the melanosome were differentially expressed in RC adults and juveniles.
