Molecular phylogenetic tree of 33 angiosperms based on 70 protein-coding genes in the cp genome. The tree was constructed by maximum likelihood (ML) analysis of the conserved regions using the RaxML program and the GTR+I nucleotide model. The stability of each tree node was tested by bootstrap analysis with 1000 replicates. Bootstrap values are indicated on the branches, and the branch length reflects the estimated number of substitutions per 1000 sites. Nelumbo was set as the outgroup.
