【Abstract】 A number of phytopathogens can produce organic acids which play an important role in plant pathogenesis as toxins. In the research reported here a bacterium, designated W-1, was discovered, which showed biological activity against oxalic acid, phenylacetic acid, tigilic acid and the toxin of Xanthomonas oryzae pv. zae , a phytopathogen responsible for rice bacterial blight. W-1 was shown to have the capacity of preventing or alleviating necrosis in tobacco caused by organic acids, removing the inhibition to rice seedling growth caused by organic acids and reducing the length of the lesions induced by X. orayzae. Such activity falls into the category of detoxification activity. An initial study has been made of the active substances in W-1 and its general biological properties. Owing to its broad-spectrum detoxificative activity, W-1 has a highly promising prospect of application in biological control of plant diseases.更多还原
