Fig. 6From: Host range of strand-biased circularizing integrative elements: a new class of mobile DNA elements nesting in GammaproteobacteriaPhylogenetic tree of SEs. The tree was constructed based on the Srap alignment using IQ-tree2 NONREV model [45]. A consensus tree is shown. An SE clade detected in Pseudomonadales is indicated by blue lines. The color of the host genus denotes the host order. Leaves indicated by the red filled squares are SEs with identifiable termini illustrated in Figs. 1 and 7, or Additional file 6. The tree is annotated and visualized using iTOL [46]Back to article page
