Results of Analyses of the Genome Contigs of Recipient Taxa Demonstrating the Evolutionary Ancestry of Genes Linked to the Plant-Fungi HGT.

This analysis demonstrates the location of the HGTs with respect to transposable elements and vertically inherited genes. In all nine cases, the analyses shows that the HGT is linked to a gene showing vertical phylogenetic inheritance or representing a gene family for which the taxon distribution suggests vertical inheritance. Because all nine HGTs are nested within a portion of native genome, DNA contamination can be ruled out as a possible source of artifact among the plant-fungus HGTs. Furthermore, in both cases that involve HGT from a fungus to the bryophyte moss P. patens, the HGT is positioned next to a putative transposable element. The alphanumeric label given in to the top right of each genome contig corresponds to Figures 1A to 4C. These data are reported in more detail in Supplemental Table 2 online.
