The legend for figure 2 was accidentally replaced with the legend of figure 1. The correct legend reads: Figure 2: Rooted phylogeny of aliphatic aminoacyl-tRNA synthetases. IleRS and ValRS are sister paralogs, with LeuRS (not shown) included as outgroup. Domains within each paralog (colored) show differing topologies due to deep horizontal gene transfer events.
