| Abstract/Contents: | "Oxalic acid has been implicated as a pathogenicity factor in Sclerotinia sclerotiorum and other necrotrophic pathogens. This simple organic acid has a variety of toxic effects on plant cells, suppresses the oxidative burst associated with early host defenses, and is required for normal pathogen development. The role of oxalate and its biosynthesis will be reviewed. Because of studies on related pathogens, it is likely that Sclerotinia homoeocarpa also produces oxalic acid during pathogenesis. In vitro studies demonstrated that S. homoeocarpa produces oxalic acid under the same conditions as S. sclerotiorum. Infection of bentgrass leaves with S. homoeocarpa or S. sclerotiorum resulted in a localized increase in oxalic acid at the infection site. Oxalic acid in tissues decreased in lines of bentgrass expressing resistance to S. homoeocarpa and in all lines inoculated with S. sclerotiorum. Oxalic acid decreases were correlated with an increase in oxalic acid oxidase activity. The bentgrass enzyme activity was partially purified and compared to known oxalate oxidases. Treatment of bentgrass leaves with potassium oxalate or methyl jasmonate induced oxalate oxidase activity and resistance to S. homoeocarpa." |
