Fig. 8From: aristaless1 has a dual role in appendage formation and wing color specification during butterfly developmentGraphical model for the role of Al1 in the specification H. cydno wing color. A White scale fate in which Al1 presence in developing scale cells lead to the inhibition of genes needed for yellow pigment uptake and production. B Yellow scale fate in which, reduced or absent Al1 results in the activation of genes involved with the production and movement of the yellow pigment 3-OHKBack to article page
