Figure 1From: Reconstruction of an ancestral Yersinia pestisgenome and comparison with an ancient sequenceYersinia pestis and pseudotuberculosis phylogeny. Tree obtained using a 1971 universal gene families concatenate. Bootstrap values are figured on the branches. For readability, the figured branch length is the inverse of the ten-logarithm of the real branch-length. The ancestral species of interest to us is figured as a red diamond. The late medieval ancient genome hypothetical position is figured in gray and dashed.Back to article page
