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 کاملA Secretory Protein of Necrotrophic Fungus Sclerotinia sclerotiorum That Suppresses Host Resistance
SSITL (SS1G_14133) of Sclerotinia sclerotiorum encodes a protein with 302 amino acid residues including a signal peptide, its secretion property was confirmed with immunolocalization and immunofluorescence techniques. SSITL was classified in the integrin alpha N-terminal domain superfamily, and its 3D structure is similar to those of human integrin α4-subunit and a fungal integrin-like protein....
متن کاملAntagonism of Aspergillus Terreus to Sclerotinia Sclerotiorum
An Aspergillus terreus strain showed in vitro antagonistic activity against the plant pathogen Sclerotinia sclerotiorum (Lib.) de Bary. The interaction between A. terreus and sclerotia revealed that the mycoparasite sporulated abundantly on the sclerotial surface. Cell breakdown due to host cell wall disruption was observed in inner rind cells, by a scanning electron microscopy.
متن کاملCharacterization of Sclerotinia sclerotiorum Isolated from Paprika
A fungal isolate collected from infected paprika (Capsicum annuum var. grossum) was characterized as Sclerotinia sclerotiorum based on its ability of sclerotium formation, physiological and molecular properties. When the isolate was grown on potato dextrose agar, oatmeal agar, and malt extract agar, it grew most well on PDA. Optimal temperature and pH for its growth were 25℃ and pH 7, respectiv...
متن کاملAscospore release and survival in Sclerotinia sclerotiorum.
The release and survival of ascospores of a UK Sclerotinia sclerotiorum isolate were studied. Apothecia placed in a spore clock apparatus with different lighting regimes at 15 degrees C released ascospores continuously with an increasing rate for the duration of experiments (72-84 h). Spore release was not confined to light or dark periods in alternating regimes and occurred in continuous dark ...
