Figure 4

Aneighbor-joining phylogenetic tree based on 16S rRNA gene sequences of siderophore-producingrepresentative strains. The tree contains the closest type strain for each isolate which belong to I, II, III, IV, V, and VI class, respectively. Bootstrap analyses were made with 1000 cycles. Only bootstrap values of > 50% are shown at the branch points. The scale bar represents 0.1 substitutions per nucleotide. I, II, III, IV, V, and VI indicated β-Proteobacreria, γ-Proteobacteria (Xanthomonadacea), Spingobacteria, α-Proteobacteria, Bacilli, andActinobacteria class, respectively.
