Figure 3From: Genome-wide identification, evolutionary and expression analysis of the aspartic protease gene superfamily in grapePhylogenetic analysis of grape and Arabidopsis APs. The conserved ASP domains of all VvAP and AtAP proteins were aligned with Clustal X 2.0.12, and the phylogenetic tree was constructed using the neighbor-joining method in MEGA 5.0. Porcine pepsin A was used as the outgroup. VvAPs that had incomplete conserved ASP domains were not included in the phylogenetic tree analysis.Back to article page
