PheRS phylogenetic tree with bootstrap scores. The 32-taxon PheRS Synthetase [16] phylogeny inferred using Neighbor-Joining [17]. The standard bootstrap scores, followed by normalized secondary bootstrap scores, are indicated above the internal branches. They are shown for the original and noisy data (the noisy data were obtained after the addition of 10% of noise to the original sequences; they are indicated under the internal branches). The bootstrap scores for the three other weighting bootstrap strategies are presented in Table 1 (encircled, are the branch numbers as they are reported in Table 1).
