Abstract
The degradation of plant cell wall by polysaccharidases is a general process by which phytopathogenic microorganisms attack and colonize host plants. Polygalacturonase (PG) is the first cell wall degrading enzyme synthesized by phytopathogenic fungi. It has been suggested that the enzyme is involved in both basic and specific compatibility between fungi and higher plants (Cervone et al 1986). It is well known that PG releases oligosaccharides from the plant cell wall which are capable of eliciting active defense mechanisms in plants (Bruce and West 1982; Walker-Simmons et al 1983) and that proteins which specifically inhibit PG activity (PGIP) are present in the plant cell wall (Albersheim and Anderson 1971). We have therefore explored the possibility that the interaction between PG and PGIP may have relevance in determining whether a plant-fungus system appears compatible or incompatible.
