Phylogentic analysis of the FtsZ-tubulin superfamily and representative operonic architectures of FtsZl1 family genes. Color code: eukaryotes - blue; bacteria - green; archaea - orange. The RELL bootstrap values (%) are indicated for selected major branches. A. Phylogeny of the FtsZ-tubulin superfamily. The tree was reconstructed from 118 phylogenetically informative positions. B. Phylogeny of FtsZl1 family. The tree was reconstructed from 103 phylogenetically informative positions. C. Genomic context of the FtsZl1 family genes. Homologous genes are shown by arrows of the same color; genes are shown not to scale. Color code for the gene context: green arrows, VWA-domain-containing proteins; red, FtsZ-like 1 family proteins; brown, OmpA-like proteins; pale blue, serine/threonine protein kinases; yellow, GTPase; empty arrows (A1-A2; B1-B9) represent families that are associated with the FtsZ-like 1 genes in many genomes (see Additional File 6); gray arrows, genes associated with the FtsZ-like 1 family genes in one or a few related genomes.
