Fig. 2From: Ommochrome pathway genes kynurenine 3-hydroxylase and cardinal participate in eye pigmentation in Plutella xylostellaGene structure (a) and phylogenetic analysis (b) of Pxkmo and Pxcardinal a Gene structure of Pxkmo (upper) and Pxcardinal (lower). Predicted splicing patterns are indicated with black boxes (exons) and broken lines (introns). Red boxes and blue dashed lines are used to mark the relative positions of transmembrane structures and conserved domains in translated proteins, respectively. sgRNAs binding sites are indicated with black arrows. b Phylogenetic trees of kmo (upper) and cardinal (lower) proteins across insect species (with Maximum Likelihood Method, 1000 bootstraps). Species name (left) and accession number (right) are listed at the terminal of tree branches. Tree scales are provided to indicate the branch lengthBack to article page
