Figure 5 in Morphogenesis of Ulva mutabilis (Chlorophyta) induced by Maribacter species (Bacteroidetes, Flavobacteriaceae)

Figure 5: Phylogenetic tree of strains of Flavobacteriaceae tested for morphogenetic activities. Maximum Likelihood (ML) phylogenetic inference of 16S rRNA gene sequences of the genus Maribacter and related genera in the family Flavobacteriaceae (phylum Bacteroidetes). Maribacter sp. strain MS6 (bold) and all type strains found to be MS6 substitutes in Ulva morphogenesis bioassays are marked in green. Test type strains which did not elicit the MS6 morphotype are marked in dark-red. For taxonomic robustness, the tree was constructed only with high-quality, ≥ 1300 bp 16S rRNA gene sequences, mostly from type strains. The gene sequence of strain MBIC04683 (349 bp) was added to the tree a posteriori using the ARB parsimony function. Numbers at tree nodes are bootstrap values calculated in ML analysis, and values ≥ 70% are shown. The unrooted tree is drawn to scale, and the scale bar represents the number of nucleotide substitutions per site (Costa et al. 2013, Keller-Costa et al. 2014). Arrows indicate strains which were identified as morphogenesis-inducing bacteria in previous studies (Matsuo et al. 2003, Spoerner et al. 2012).
