Sclerotinia sclerotiorum D-E7 was studied to determine the impact of nutritional supplements and monosaccharides on growth, oxalate accumulation, and culture pH in broth media (initial pH c. 5). Cultures with 0.1% nutritional supplement (tryptone, yeast extract, or soytone) yielded minimal growth, 2-3 mM oxalate, and a final culture pH of 4.2-4.8. In contrast, cultures with 0.1% nutritional sup...

Phytopathogenic fungi form intimate associations with host plant species and cause disease. To be successful, fungal pathogens communicate with a susceptible host through the secretion of proteinaceous effectors, hydrolytic enzymes and metabolites. Sclerotinia sclerotiorum and Botrytis cinerea are economically important necrotrophic fungal pathogens that cause disease on numerous crop species. ...

sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of them medicinal plant. in this study the extract obtained from basal stalk rot of helianthus annuus l., attacked by s. sclerotiorum, was subjected to the analysis of ftir to identify the presence of beta-glucan. ft-ir spectrum showed four ranges of bands in 890 cm-1, two overlap band in 1047 and 1078 ...

Single-molecule fluorescence spectroscopy in condensed phases has many important chemical and biological applications. The single-molecule fluorescence measurements contain information about conformational dynamics on a vast range of time scales. Based on the data analysis protocols methodology proposed by X. Sunney Xie, the theoretical study here mainly focuses on the single-molecule studies o...
