Fig. 1.

Phylogenetic distribution of operational taxonomic units (OTUs) of fluorescent pseudomonads (FPs) isolated from the phyllosphere and rhizosphere of potato plants cultivated in various locations across Japan. The dendrogram indicates the phylogenetic relationships among the representative sequences of OTUs (defined by ≥99% identity). The table indicates the relative abundance (%) of clones belonging to each OTU in each column and the results of a pair-wise BLAST between a representative sequence and its closest type strain. The sampling sites (prefecture) were as follows: FUK, Fukuoka; HOK, Hokkaido; IBA, Ibaraki; KAG, Kagoshima; KAN, Kanagawa; NAG, Nagasaki. The percentages of isolates analyzed are shown for each column of libraries. “*” and “**” mean statistical significance at 0.05 and 0.01 levels, respectively.
