Suspected timing of appearance of GNATs, INVs and CMs in Hoplolaimina PPN. (a-c) Cladograms are shown as in Fig. 1B. Lineages, and species within, that were found to contain homologs of the HGT genes in question are colored red. The suspected timing of appearance of GNATs (a), INVs (b) and CMs (c) are illustrated with a red circle placed on the appropriate branch. Note that species within a red Hoplolaimina lineage (family or subfamily) that are not colored red does not mean that they do not contain that particular gene, it means that we could not identify that gene in their sequence data, which may be due to insufficient sequence data rather than gene loss. The same goes for the Radopholinae lineage, as Radopholus similis was the only species included, which has only limited EST sequences
