The phylogenetic tree based on 16S rDNA sequences constructed using the Maximum Likelihood method based on the Kimura 2-parameter model shows the taxonomic positions of 12 endophytic actinomycetes isolates of Panax sokpayensis. The percentage of trees in which the associated taxa clustered together is shown next to the branches. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site.
