FIG. 2.

Phylogenetic trees showing the relationships among the 16S rDNA sequences of three PhlD⁺ isolates and reference 16S rDNA sequences of organisms belonging to the gamma subclass of the class Proteobacteria. (A) Relationships of isolate 3-1 and fluorescent Pseudomonas spp. The outgroup sequence used was the sequence of A. calcoaceticus ATCC 33604, (accession no. M34139). (B) Relationships of isolates 3-45 and 16-31 and members of the family Enterobacteriaceae. The outgroup sequence used was the sequence of P. putida JCM 6156 (accession no. D37924). The sequence positions used for alignment were positions 48 to 1468 (A) and 37 to 1370 (B) (Escherichia coli numbering).
