In summer 2018, brown stripe symptoms were observed on leaf blades of perennial ryegrass (Lolium perenne L.) used as a turfgrass in an athletic field in Saitama Prefecture, Japan. Bacterial ooze exuded from lesions, from which a pathogenic bacterium was isolated. Inoculation of blades of perennial ryegrass with the isolates reproduced the same symptoms. Pathogenicity and bacteriological properties of the isolates were almost identical to those of Acidovorax avenae, and the identification was supported by phylogenetic analysis. This is the first report of the brown stripe on perennial ryegrass caused by A. avenae (= A. avenae subsp. avenae) in Japan. [ABSTRACT FROM AUTHOR]
