USES OF THE PSEUDOMONAS SYRINGAE EFFECTOR PROTEIN HOPU1 RELATED TO ITSABILITY TO ADP-RBOSYLATE EUKARYOTC RNA BINDING PROTENS

The bacterial plant pathogen Pseudomonas Syringae injects effector proteins into host cells via a type III protein secre tion system to cause disease. The invention relates to the discovery that the type III effector HopU1 is a mono-ADP ribosyltransferase (ADP-RT) and suppresses plant innate immunity. The HopU1 substrates in Arabidopsis thaliana extracts were RNA-binding proteins that possess RNA recognition motifs (RRMs). A. thaliana knock-out lines defective in the glycine-rich RNA-binding protein AtGRP7, a HopU1 substrate, were more susceptible than wild type plants to P syringae. The ADP-ribosylation of AtGRP7 by HopU1 required two arginines within the RRM. The inven tion provides novel methods for the modulation of the innate immune response of a plant to a biotic stress, including methods for enhancing or suppressing the innate immune response of the plant
