Abstract

Systemic Acquired Resistance (SAR) to pathogens is directly correlated with a build up of salicylic acid (SA) in non-infected leaves. SA synthesis depends on benzoic acid and H202 production and is limited to tissue surrounding cells undergoing HR. We will engineer SAR in the absence of avirulent pathogen attack by controlled SA synthesis from chorismate, a constitutively available precursor. A bacterial SA-synthesis pathway will be mimicked by controlled expression of a plant isochorismate synthase gene (that we have recently identified) in conjunction with a 2nd bacterial enzyme which converts isochorismate into SA. SA synthesis and SAR will be monitored in transgenic plants and if successful will allow future modification of SAR in crops.
