Phylogenetic tree the genus Gramella and closely related genera of the family Flavobacteriaceae. The tree was inferred from 1,409 aligned characters of the 16S rRNA gene sequence under the maximum likelihood (ML) and maximum parsimony [MP] criterion as previously described by Göker et al. [51]. The sequences of the LTP v. 121 database [52, 53] and from GenBank were aligned in ARB [54] using the SINA aligner [39] and manually corrected. The branches are scaled in terms of expected number of substitutions per site. Numbers adjacent to the branches are support values from 1,000 ML bootstrap replicates (left) and from 1,000 maximum-parsimony bootstrap replicates (right) if larger than 60 % [51]. Numbers in wedges represent the numbers of sequences. The tree was rooted using type strains of the genera Doktonia, Aquimarina, Salinimicrobium, Psychroflexus, Gillisia and Mesonia
