Figure 4.

Phylogenetic relationship of Pseudoalteromonas strains that have been tested for their ability to induce coral larval settlement. Strains that have been shown to induce coral larval settlement are indicated by a plus symbol (+); Pseudoalteromonas sp. PS5 from this study is shown in bold. Tree is based on 1360 bp of the 16S rRNA gene using Minimum Evolution method (Jukes–Cantor model). Numbers beside nodes indicate the level of bootstrap support as a percentage out of 1000 replicates. Evolutionary analyses were conducted in MEGA5. Superscript numbers denote as follows: ¹Tebben et al. [16], ²Negri et al. [15], ³Tran & Hadfield [14].
