Fig. 9From: A reference gene set for sex pheromone biosynthesis and degradation genes from the diamondback moth, Plutella xylostella, based on genome and transcriptome digital gene expression analysesPhylogenetic tree and intron positions of PxCCE genes. The nomenclatures of clades are based on previously published data. The intron positions in sequences are shown as (|) for a phase 0 intron, ([) for a phase 1 intron and (]) for a phase 2 intron. Arrows indicate the most conserved intron insertion site in PxCCEs. Same color brackets indicate the same intron insertion site among different genesBack to article page
