Abstract
The phylogenetic relationships of 51 isolates representing 27 species of Phytophthora were assessed by sequence alignment of 568 bp of the mitochondrially-encoded cytochrome oxidase II gene. A total of 1299 bp of the cytochrome oxidase I gene also was examined for a subset of 13 species. The cox II gene trees constructed by a heuristic search based on maximum parsimony for a bootstrap 50% majority-rule consensus tree revealed 18 species grouping into 7 clades and 9 species unaffiliated with a specific clade. The phylogenetic relationships among species observed on cox II gene trees did not exhibit consistent similarities in groupings for morphology, pathogenicity, host range or temperature optima. The topology of the cox I gene trees constructed by a heuristic search based on maximum parsimony for a bootstrap 50% majority-rule consensus tree for 13 species of Phytophthora revealed 10 species grouping into 3 clades and 3 species unaffiliated with a specific clade. The groupings in general agreed with what was observed in the cox II tree. Species relationships observed for the cox II gene tree were in general agreement with those based on ITS regions, with some notable exceptions. Analysis of combined data sets of ITS and cox II generated a tree that did not differ substantially from analysis of ITS data alone, however, the results of a partition homogeneity test suggest that combining data sets may not be valid.
