Evidence for Plant-Fungi HGT Based on a Prokaryote Tagged-Chain Transfer Hypothesis.

In the absence of strong phylogenetic tree topological support, it has been argued that a putative eukaryote-to-eukaryote HGT can be inferred when it is rooted by an uncontroversial case of prokaryote-to-eukaryote HGT. We detected two additional examples of HGT supported by this form of evidence.

(A) Phylogeny of the putative bifunctional iucA/iucC siderophore biosynthesis protein.

(B) Phylogeny of the unknown/conserved hypothetical protein. All phylogenies are reduced versions of the tree figure and the phylogenetic analysis implemented. See Supplemental Figures 5 and 6 online for full details. The figures are labeled using the same conventions described for Figure 1.
