Phylogenetic analysis, conserved motifs, and gene structure of VQ in wheat. A Phylogenetic tree of 113 VQ proteins in wheat constructed based on the results of sequence alignment. The tree was created with 1000 bootstraps using the neighbor-joining (NJ) method in MEGA7. B Motif compositions of 20 conserved motifs of the VQ protein in wheat were identified by the MEME tool. Each specific motif is indicated by a different colored box; detailed motif information is shown in Additional file 4: Table S3. C Gene structure of the VQ genes in wheat from the GSDS database. Exons are indicated by yellow rectangles, UTR is indicated by blue rectangles, and lines connecting two exons represent introns. Box and line length are displayed proportionally to gene length
