Abstract

Roots of E. marginata exposed to hypoxia show increased resistance to infection by P. cinnamomi. A more rapid production of phenolics has previously been shown to be related to increased resistance in clonal E. marginata. Phenolics are secondary plant metabolites formed from the phenylpropanoid pathway and are involved in both chemical (phytoalexins) and physical (strengthening of the cell wall) plant defence (3). In this study, the effect of the duration of hypoxia on infection development and phenolic accumulation in E. marginata inoculated with P. cinnamomi was examined.
