Oxalic acid, a pathogenicity factor for Sclerotinia sclerotiorum, suppresses the oxidative burst of the host plant.
Effective pathogenesis by the fungus Sclerotinia sclerotiorum requires the secretion of oxalic acid. Studies were conducted to determine whether oxalate aids pathogen compatibility by modulating the oxidative burst of the host plant. Inoculation of tobacco leaves with an oxalate-deficient nonpathogenic mutant of S. sclerotiorum induced measurable oxidant biosynthesis, but inoculation with an ox...
متن کاملOxalic Acid Has an Additional, Detoxifying Function in Sclerotinia sclerotiorum Pathogenesis
The mechanism of the diseases caused by the necrotroph plant pathogen Sclerotinia sclerotiorum is not well understood. To investigate the role of oxalic acid during infection high resolution, light-, scanning-, transmission electron microscopy and various histochemical staining methods were used. Our inoculation method allowed us to follow degradation of host plant tissue around single hyphae a...
متن کاملVariation in Sclerotinia sclerotiorum Bean Isolatesfrom Multisite Resistance Screening Locations
Otto-Hanson, L., Steadman, J. R., Higgins, R., and Eskridge, K. M. 2011. Variation in Sclerotinia sclerotiorum bean isolates from multisite resistance screening locations. Plant Dis. 95:1370-1377. There is no complete resistance to Sclerotinia sclerotiorum, cause of white mold in dry bean (Phaseolus vulgaris). Variable resistance expression is one problem in screening for improved white mold re...
متن کاملReaction of common bean lines and aggressiveness of Sclerotinia sclerotiorum isolates.
The aims of this study were to evaluate the reaction of common bean lines to white mold, the aggressiveness of different Sclerotinia sclerotiorum isolates from various common bean production areas in Brazil, and comparison of the diallel and GGE (genotype main effect plus genotype-by-environment interaction) biplot analysis procedures via study of the line-by-isolate interaction. Eleven common ...
