Phytophthora infestans | Phylogeny

The phylogenetic position of Phytophthora infestans relative to two other stramenopiles is shown in the following tree, which was constructed using the derived protein sequences of the mitochondrial nad4L genes. The bootstrap support (in percentage) clearly indicates that Phytophthora is not a member of the eufungi. However, the position of deeply rooted species within the stramenopiles proved tenuous and would best be examined in conjunction with the analysis of much longer protein sequences.
