Abstract

Phylogenetic relationships in Hyaloperonospora (Oomycetes) were investigated by molecular analyses using internal transcribed spacer (ITS) sequences and collections from different host plants. Trees were inferred with Bayesian Markov chain Monte Carlo, neighbor-joining and maximum parsimony methods and rooted with Perofascia. The results are discussed with respect to host taxonomy and species concepts of downy mildews from the literature. Molecular data mainly support the use of narrow species delimitations and host range as a taxonomic marker. Hyaloperonospora brassicae turns out to be a non-monophyletic assemblage of different species. New combinations are proposed in accordance with the phylogenetic trees.
