A role for beta-sitosterol to stigmasterol conversion in plant-pathogen interactions.
Upon inoculation with pathogenic microbes, plants induce an array of metabolic changes that potentially contribute to induced resistance or even enhance susceptibility. When analysing leaf lipid composition during the Arabidopsis thaliana-Pseudomonas syringae interaction, we found that accumulation of the phytosterol stigmasterol is a significant plant metabolic process that occurs upon bacteri...
متن کاملRole of Silicon on Plant–Pathogen Interactions
Although silicon (Si) is not recognized as an essential element for general higher plants, it has beneficial effects on the growth and production of a wide range of plant species. Si is known to effectively mitigate various environmental stresses and enhance plant resistance against both fungal and bacterial pathogens. In this review, the effects of Si on plant-pathogen interactions are analyze...
متن کاملIsolation of Stigmasterol and β-Sitosterol from the dichloromethane extract of Rubus suavissimus
Purification of the dichloromethane (CH2Cl2) fraction of the aqueous extract of Rubus suavissimus resulted in the isolation of two sterols namely stigmasterol and β-sitosterol. The structures of the isolated compounds were characterized on the basis of extensive spectral data (1D and 2D NMR; and MS) and in comparison with their literature data.
متن کاملSolubility Limits of Cholesterol, Lanosterol, Ergosterol, Stigmasterol, and β-Sitosterol in Electroformed Lipid Vesicles.
Here we use nuclear magnetic resonance to measure the solubility limit of several biologically relevant sterols in electroformed giant unilamellar vesicle membranes containing phosphatidylcholine (PC) lipids in ratios of 1:1:X DOPC:DPPC:sterol. We find solubility limits of cholesterol, lanosterol, ergosterol, stigmasterol, and β-sitosterol to be 65-70%, ~35%, 30-35%, 20-25%, and ~40%, respectiv...
متن کاملIsolation of Β-sitosterol & Stigmasterol as Active Immunomodulatory Constituents from Fruits of Solanum Xanthocarpum (solanaceae)
General phytochemical screening of the aqueous extract of fruits of Solanum xanthocarpum (Solanaceae) revealed the presence of steroids, terpenes, phenolic compounds, saponins, fatty acids, alkaloids. Fractionation of aqueous extract and activity guided isolation resulted in isolation of two white crystalline powder which were subjected to physical, chemical and spectral identification using IR...
