Phylogenetic Analysis, Motif Composition, and Gene Structure of VcWOX Proteins in Grape

The conserved domains and motifs of VcWOX proteins are depicted. (A) The phylogenetic tree of VcWOX proteins, clustered into three groups (I-III). (B) The motif composition of VcARF proteins. Protein motifs of VcARF were identified using the MEME program and are represented by different colored boxes. (C) The exon/intron structure of VcWOX genes, with exons depicted as green rectangles and introns as thin lines. Yellow rectangles represent upstream/downstream regions (5'UTR and 3'UTR). (D) Sequence logos for 20 patterns. The height of the letters in each stack indicates the relative frequency. Symbols correspond to the colored boxes in panel B.
