They found a genetic mutation in a corn snakes that gives a lavender pigment in their scales. The skin color of vertebrates depends on chromatophores. This specific type of color variation is a dull color of the lavender variation. This is caused by a mutation in a gene involved in forming lysosomes. This single mutation can affect all skin color, which shows that the reflective crystals and pigments are stored in the lysosome. The chromatophores are what determine the skin color due to the pigment and reflected crystals that reflects lights. In which their are three types of chromatophores which are melanophores, xanthophores, and iridophores. The melanophores are responsible for the black and brown colors, xanthophores are responsible for red and yellow color, and iridophores are the crystals that reflect multiple colors. The lavender mutation contains a pink coloration with grey spots and this mutation is due to a single gene in the LYST gene. This gene regulates the trafficking of lysosomes. Scientists studied the snakes main their hepatocytes which are contained in the main liver. Hepatocytes are the main cells of the livers which are in charge of metabolic, endocrine and secretion functions. The scientists found that the hepatocytes in lavender snakes are contained more aggressive lysosomes which will give the lavender skin color. I was really in to this article because there's been a lot of studies done on snakes on their scale colors. Snakes have a lot of different alleles that control their scale colors. To know that another color was created due to a mutation I think its pretty cool.
