Figure 1. 16S phylogenetic tree.

Neighbour-joining phylogenetic tree of Photobacterium species based on 16S rRNA gene sequences (1,525 nt) showing the position of P. sanctipauli sp. nov. The optimal tree with the sum of branch length = 0.35538897 is shown. The evolutionary distances were computed using the Jukes-Cantor method. All positions containing alignment gaps and missing data were eliminated only in pairwise sequence comparisons (Pairwise deletion option). Phylogenetic analyses were conducted in MEGA5. Bootstrap values (>50%) based on 1,000 resamplings are shown. Salinivibrio was used as outgroup. Bar, 1% estimated sequence divergence.
