Fig. 27.1 Phylogenetic tree of the 16S rRNA gene sequence obtained from isolate USC-633 and closest relatives from
the genus Streptomyces and other members of the order Actinomycetales (adapted from Kurtböke [27.81]). Numbers at
branch node points representing values (only values > 50% are shown). The scale bar represents 1% sequence divergence. GenBank accession numbers of reference sequences are presented in parentheses. Arthrobacter aurescens was
used as an outgroup sequence to root the tree
