FIG 2.
Maximum-likelihood phylogenetic tree of the family Streptosporangiaceae based on 16S rRNA gene sequences, showing relationships between isolates representing putative novel phylotypes (in boldface font) and related members of the Streptosporangiaceae. DDBJ/EMBL/GenBank accession numbers are shown in parentheses. Bootstrap values of the NJ and ML analyses are shown above the internodes before and after the backslash, respectively, and posterior probabilities of the Bayesian analyses (≥0.95) are shown below the internodes; only values above 50% are given. The tree was rooted by novel isolate Actinomadura sp. strain FXJ1.1129 and Actinomadura madurae DSM 43067T. Bar, 0.005 substitutions per site. *, strain is moderately acidophilic.
