Structural elucidation of a cell wall fungal polysaccharide isolated from Ustilaginoidea virens, a pathogenic fungus of Oriza sativa and Zea mays.
The alkali-extractable water-soluble polysaccharides (F1SS) isolated from the outer cell wall of two strains of Ustilaginoidea virens have been studied by chemical and methylation analyses, and 1D and 2D (1)H and (13)C NMR spectroscopy. The structures of these polysaccharides are very similar, and can be described by the following idealized repeating unit: where n and m are approximately 1 and 2, respectively.
