The cinnabar and white genes of GWSS. (a,b) The structure of the GWSS cn and w genes. Exons containing untranslated regions (white bars) and coding regions (black bars), introns (lines), PCR primers (black arrows), and sequence of sgRNA regions (underlined), and PAM sites (red) are shown. The target site of sgRNAs in indicated with a red arrow. Conserved protein domains identified by SMART tool included cinnabar’s FAD-binding (navy) and two transmembrane domains (maroon) and white’s conserved AAA motif (brown), ABC2 (teal), and transmembrane domain (maroon). Scale bars = 1000 bp. (c) Phylogenetic tree of cinnabar, pale and vermillion proteins that encode enzymes of the ommochrome pathway (kynurenine 3-monooxygenase, tyrosine 3-monooxygenase, and tryptophan 2,3-dioxygenase, respectively). (d) Phylogenetic tree of white, brown and scarlet ABC transporters. (e) The ommochrome and pteridine pathways of Drosophila melanogaster.
