Abstract

Bacterial leaf streak of wild rice (Zizania aquatica ) is characterized by narrow, translucent, water-soaked lesions that eventually become brown or black and dry. Isolations from diseased plants collected in northern Minnesota from 1976 to 1980 yielded 167 cultures of Pseudomonas syringae and 21 cultures of Xanthomonas campestris . Strains from both species were pathogenic to wild rice. Three X. campestris strains were similar to pv. cerealis and one to pv. translucens . Strains of P. syringae were biochemically similar to pv. striafaciens , but were pathogenic only to wild rice. The name P. syringae pv. zizaniae pv.nov. is proposed.
