In July 2009, yellowing and irregularly-shaped lesions on the leaves of komatsuna (Brassica rapa var. perviridis) were observed in a plastic greenhouse in Ibaraki Prefecture, Japan. The pathogen was identified as Hyaloperonospora brassicae based on the morphological features of conidiophores and conidia, the sequence of rDNA-ITS region and host range of the pathogen.
