Tree reconciliation analysis. a Species tree cladogram. The root was arbitrarily placed between Bacteria and Eukaryota + Archaea. Branches are numbered according to the.uTs ALE file. b Sum of the observed frequencies of transfer from branches (numbered in a) leading to Eukaryota, Archaea and Bacteria occurring in 100 gene phylogenies sampled from a gene tree space of 39,504 trees. See Methods for further details. Aerobes were found to act as HGT donors to Anaerobes more often than the other way round. Branch 103, leading to two euryarchaeal methanogens (M. intestinalis, M. luminyensis), is found to be the preferential donor in the HGT involving T. vaginalis. Colour codes as in Fig. 1
