FIGURE 2. Molecular phylogeny of Timaviella based on the 16S rRNA gene concatenated with the 16S-23S ITS sequence comparisons. A phylogenetic tree was inferred by the Maximum Likelihood method with Maximum Likelihood bootstrap support (BP) and Bayesian Posterior Probabilities (PP). From left to right, support values correspond to Maximum Likelihood BP and Bayesian PP; BP values lower than 50% and PP lower than 0.8 not shown. Strain in bold represents newly sequenced cyanobacteria. Authentic strains marked with asterisk.

Fig. 1 in Arenibacillus arenosus gen. nov., sp. nov., a member of the family Rhodobacteraceae isolated from sea sand
Fig. 1. Maximum-likelihood phylogenetic tree based on nearly complete 16S rRNA gene sequences showing the relationships of strain CAU 1304T to members of related genera of the family Rhodobacteraceae. Filled circles indicate that the corresponding nodes were also recovered in the trees generated with the neighbour-joining and maximum-parsimony algorithms. The numbers at nodes indicate levels of bootstrap support based on a maximum-likelihood analysis of 1000 resampled datasets; only values>70 % are given. Bar, 0.01 substitutions per nucleotide position. Pelagicola litoralis CL-ES2T (EF192392) was used as an outgroup organism.
