Sequence alignment for 7 gene regions for new Phytophthora species in clade 2a

Five new taxa from Phytophthora ITS Clade 2a are described from Cinnamomum cassia plantations and adjacent waterways in Van Yen, Vietnam, and disturbed rainforest in the Hela Province of Papua New Guinea and from disturbed forest on Christmas Island. Phylogenetic analyses were performed using data from nuclear regions (ITS, β-tubulin; Heat shock protein 90) and mitochondrial regions (cytochrome c oxidase subunit 1; cytochrome c oxidase subunit2; NADH dehydrogenase subunit 1; ribosomal protein L10). The molecular data supported recognition of three species: Phytophthora insulinativitatica, P. multibullata and P. x vanyenensis and two informal taxa, P. sp. germisporangia and P. sp. awatangi. P. x vanyenensis appears to be a hybrid between P. sp. mekongensis and an unknown species. P. multibullata and P. sp. germisporangia are phylogenetically close to P. citrophthora, but morphologically distinct. P. insulinativitatica is most closely related to P. botryosa but has different morphology. P...
