Percentage of HGT transcripts in parasitic Rafflesia cantleyi and its obligate host Tetrastigma rafflesiae . These species are similarly contrasted against two autotrophic species that are closely related to Rafflesia, Manihot esculenta and Ricinus communis. Placements consistent with HGT in the latter two non-host, non-parasitic malpighialean taxa as defined for Rafflesia provide an estimate of the rate of non-HGT related factors that contribute to phylogenetic discordance. Species belonging to the Malpighiales and Vitaceae clade are shown in red and blue, respectively. The total number of transcripts used as denominators to calculate percentages are shown in parentheses.
