Figure 1From: Paths of lateral gene transfer of lysyl-aminoacyl-tRNA synthetases with a unique evolutionary transition stage of prokaryotes coding for class I and II varieties by the same organismsArchaeal tree. Species tree for 19 Archaea encoding LysRS1 and LysRS2. Organisms coding for LysRS1 are colored blue, those coding for LysRS2 are in red, and the three Archaea that code both are in purple. Arrows indicate inferred LGT events.Back to article page
