Abstract
Downy mildew is probably the most widespread and potentially destructive disease of spinach (Spinacia oleracea) worldwide. The causal agent of downy mildew on various plants of Chenopodiaceae, including spinach, is currently regarded as a single species, Peronospora farinosa. In the present study, ITS rDNA sequence and morphological data demonstrated that P. farinosa from Spinacia oleracea is distinct from downy mildew of other chenopodiaceous hosts. A total of 58 specimens of spinach were collected or loaned from 17 countries of Asia, Europe, Oceania, North and South America, and all specimens formed a distinct monophyletic group. No intercontinental genetic variation of ITS rDNA was found within Peronospora accessions causing spinach downy mildew disease worldwide. Phylogenetic trees supported recognition of Peronospora from spinach as a separate species. In microscopic examination, Peronospora specimens from Spinacia also revealed morphological differences from P. farinosa specimens from Atriplex, Beta, and Chenopodium. Consequently, the name Peronospora effusa should be reinstated for the downy mildew fungus on spinach. A specimen among the original collections of Peronospora effuse was designated as lectotype here.
