Abstract
A small family of necrosis-inducing peptides has been identified as virulence factors of Rhynchosporium secalis, a fungal pathogen of barley (Hordeum vulgare L.) Two members of this family, NIP1 and NIP3, were found to stimulate the phosphohydrolyzing activity of the Mg2+-dependent, K+-stimulated H+-ATPase of plasma membrane vesicles isolated from barley leaves by partitioning in an aqueous two-phase system. Stimulation of enzyme activity was saturated by 10 to 15 [mu]M fungal protein. Another member of the peptide family, NIP2, did not affect the enzyme, indicating that it has a different mode of action.Entities:
