Figure 4: Phylogenetic relationships of Synechococcus sp. 1Dp66E-1 inferred under the neighbor-joining (NJ) criterion (MEGA 5.1 [14]) from gene for 16S rRNA, partial sequence; 16S-23S rRNA intergenic spacer, complete sequence; and 23S rRNA, partial sequence information. The numbers at the nodes indicate the level of bootstrap support based on neighbor-joining analysis of 1000 resampled datasets; only values higher than 50% are given. The scale bar indicates 0.01 substitutions per nucleotide position.
