Analysis of the conserved motifs and gene structures of RVE genes in Arabidopsis and Pyrus bretschneideri. (a) Conserved motifs of PbRVE and AtRVE proteins. Ten conserved motifs were predicted by MEME. Different colored boxes represent different motifs. The proteins are arranged according to the phylogenetic tree. PbRVE proteins are labeled with yellow circles, and AtRVE proteins are labeled with green squares. (b) Exon–intron structure of PbRVE and AtRVE genes. Blue boxes, orange boxes, and gray lines represent exons, UTRs and introns, respectively
