Abstract

The aim of this project is to test the hypothesis that volatile chemical signals emitted by plants subjected to pathogen attack can influence the disease response of adjacent uninfected plants when subsequently exposed to pathogen challenge, and that such interactions are a significant component of the enhanced disease resistance of crop genotype mixtures. Necrotrophic foliar pathogens of barley are being used as the test system to investigate: 1. The chemical profile of volatiles emitted from resistant and susceptible genotypes inoculated with virulent and avirulent isolates of the pathogen. 2. The effects of volatile emissions entrained from inoculated plants on the disease reaction of susceptible genotype x isolate combinations. 3. The effect of volatile emissions and defined chemical fractions on specific pathogen developmental stages including spore germination, germ tube extension and penetration of the host. 4. The effect of volatile emissions and defined fractions on plant defence gene expression utilising known molecular indicators of induced resistance including salicylate and jasmonate responsive genes. 5. The potential involvement of novel plant defence pathways by deploying genomic, metabolomic and proteomic approaches
