Obiettivo Attempted infection can result in systemic acquired resistance (SAR)- the development throughout the plant of immunity to subsequent attack by a broad range of normally virulent pathogens. TheArabidopsis mutant defective in induced resistance 1-1 (dirl-1) exhibits wild-type local resistance toavirulent Pseudomonas syringe, but defence gene expression is abolished in distant leaves and dirl-1fails to develop SAR to virulent Pseudomonas or Peronospora parasitical. Petiole exudates experiments indicate that dirl-1 is defective in the production or transmission from the inoculated leaf of inessential mobile signal. DIR1 encodes a putative apoplectic lipid transfer protein (LTP) and we propose that DIR1 interacts with a lipid-derived molecule to promote long distance signalling. The proposed study will determine how the DIR1 protein functions and thus reveals how to enhance the capacity of plants to develop SAR.
