Phylogenetic relationship, gene structures and conserved motifs of CaAAAPs. A Phylogenetic tree of 53 CaAAAPs proteins. Neighbor-joining tree was constructed using MEGA7. Bootstrap support values from 1000 reiterations are indicated at each node. The 53 CaAAAPs in the tree were divided into eight subfamilies. B Exons and introns were indicated by green rectangles and gray lines respectively. C Conserved motifs of CaAAAPs proteins. Each colored box represents a specific motif in the protein identified using the MEME motif search tool. The order of the motifs corresponds to their position within individual protein sequences
