Molecular phylogenetic tree based on 79 protein-coding genes of 21 Asteraceae chloroplast genomes. Achyrachaena mollis set as the outgroup. The tree was constructed by maximum likelihood analysis of the conserved regions using the RAxML program and the GTRI 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
