Phylogenetic and gene structural analysis of rose AP2/ERF transcription factors. The phylogenetic tree is constructed by MEGA6.0 using a Neighbor-joining method. Numbers on the nodes of the branches represent bootstrap values. The gene structure diagram represents UTRs, exons and introns with green boxes, yellow boxes and gray lines, respectively. The scale at the bottom estimated the size of UTRs, exons and introns
