Analyses of phylogenetic relationships and conserved domains of ZxARFs. 30 ARFs of Z. xanthoxylum were used for constructing an unrooted tree using the maximum likelihood method with 1000 bootstrap replications by MEGA-X. These ZxARFs divided into 3 Clades (A-C), which were exhibited in red, blue, and green, respectively. Lengths of each domain are displayed proportionally. The blue boxes represent B3 domains, green boxes represent ARF domains, and purple boxes represent PB1 domains. The blue and purple solid circle represents the absence of B3 domain and PB1 domain, respectively
