Abstract
Salicylic acid (SA) potentiates plant defence responses, probably through an effect on the generation or perception of the oxidative burst during the hypersensitive response (HR). We aim to study the interaction of AOS and SA signalling on the redox- sensitive AoPR1 promoter whose activation accompanies cell death in the HR. We will locate more precisely sequences required for redox-activation in the AoPR1 promoter and evaluate effect of cellular redox-status on interaction of transcription factors with putative NFkB, AP1 and cMyc/Max binding sites. Finally, we will determine whether potentiation of AoPR1 induction by SA operates via a direct effect on transcription factors which is evident following subsequent redox-stress or pathogen attack.
