Phylogenetic relationship among Solanaceae species. The Cape gooseberry, P. peruviana is phylogenetically branched out before the divergence of the other five Solanaceae family members: S. lycopersicum, S. tuberosum, Capsicum spp, S. melongena and Petunia spp. The numbers are bootstrapping values. The tree was constructed using the amino acid substitution model with PhyML package.
