Phylogenetic relationships among the bacteria isolates from the ascidian C. dellechiajei and their relatives. (a) Neighbour-joining tree using Jukes-Cantor correction based on 16S rRNA gene partial sequences (430 bp) from strains Dell4-Dell8 and complete sequence (1435 bp) from strain Dell9 related to alpha-proteobacteria. Numbers at the branch nodes are quartet puzzling support values (normal face) and bootstrap values (1000 replicates) (italic face). The bacterium Escherichia coli was used as the outgroup. The horizontal scale bar represents 0.1 substitution per nucleotide position. (b) Neighbour-joining tree using Jukes-Cantor correction based on partial sequences (430 bp) of 16S rRNA gene from strains Dell1–Dell3 related to gamma-proteobacteria. Numbers at the branch nodes are quartet puzzling support values (normal face) and bootstrap values (1000 replicates) (italic face). The archaeon Halobacterium salinarum was used as the outgroup. The horizontal scale bar represents 0.1 substitution per nucleotide position.
