Phylogeny, conserved motifs and gene structures of P450 genes in Chinese white pear. a The phylogenetic tree of the full-length sequences of Chinese white pear P450 proteins was constructed using IQ-TREE. b Motif compositions of the P450 proteins in Chinese white pear. MEME tools were used to identify motifs. Ten motifs (motifs 1–10) are indicated by different colors. The scale below represents the length of a protein. c Gene structures of P450 genes in Chinese white pear. The green boxes indicate untranslated 5′- and 3′-regions, and the black lines indicate introns. The numbers indicate the phase of the corresponding intron
