Phylogenetic tree highlighting the position of M. tractuosa relative to the other type strains within the family Flammeovirgaceae. The trees were inferred from 1,408 aligned characters [7,8] of the 16S rRNA gene sequence under the maximum likelihood criterion  and rooted in accordance with the family Sphingobacteriaceae. The branches are scaled in terms of the expected number of substitutions per site. Numbers above branches are support values from 1,000 bootstrap replicates  if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD  are shown in blue, published genomes in bold.
