Figure 1From: Phylogenetic spectrum and analysis of antibacterial activities of leaf extracts from plants of the genus RhododendronPhylogenetic tree based on bacterial 16S rRNA gene sequences. The phylogenetic tree was constructed using the neighbor-joining method showing the bacterial organisms (numbers in brackets) used in this study. Bootstrap values (1,000 replicates) lower than 50% are not shown. â–² Filled triangles indicate the phylogenetic position of human pathogens which have not been used in this study. The scale bar 0.02 indicates 2% of nucleotide sequence substitution. The strain numbers are indicated in brackets.Back to article page
