Phylogenetic tree of genome-sequenced actinomycete strains based on 16S rRNA gene sequences. Strains harboring biosynthetic gene clusters for rakicidin and the related compound are shaded in black. Strains are colored according to the group shown in Fig. 4: Fig. 4a, white; Fig. 4b, blue; Fig. 4c, yellow; Fig. 4d, green and red. Strains whose 16S rRNA gene sequences are neither registered nor almost complete are excluded from this analysis
