The conserved motifs and gene structure analysis of PUB gene family in pear. a A Neighbor–Joining (NJ) phylogenetic tree of 62 pear PUB genes. The phylogenetic tree was constructed by Mega-X with 1000 bootstrap. The red branches indicated group I; the blue branches indicated group II; the orange branches indicated group III; the green branches indicated group IV; the purple branches indicated group V; b The conserved motifs analysis of PbrPUB genes in pear. A total of 20 motifs were predicated by MEME tool, named Motif 1–20. The scale bar indicates 200 aa; c The gene structure analysis of PUB genes in pear, including UTR, intron and exon. The green rectangles represented UTR; the yellow rectangles represented Exon; the grey lines presented Intron. The scale bar indicates 2 kb
