Maximum likelihood phylogenetic inferences of O. colligata’s septin 7 (M896_080490) and similar protein sequences. All protein sequences displaying similarity greater than the selected cutoff (E value cutoff 1E to 40; accession date, 20 August 2014) were retrieved from the NCBI NR database. The best ML tree (LG+Γ4) is shown here. The major nodes retrieved in all bootstrap replicates are indicated by asterisks, whereas numbers indicate the corresponding levels of bootstrap support (values lower than 60 are not shown). Daphnia paralogous clades are color coded with a bluish gradient and labeled A to D. Their specific functions (e.g., that of septin 2, 4, 6, or 7) are not clear. Branch lengths are drawn to scale.
