Abstract

Callus cultures initiated from Australian native and horticultural species with varying degrees of field resistance or tolerance to the fungal pathogen Phytophthora cinnamomi were screened for expression of resistance to the pathogen. The extent of hyphal growth on callus correlated with the susceptibility of the plant from which the callus was derived. The optimum temperature for fungal growth on the calli was 30 C. This was the temperature at which the difference was greatest between hyphal growth on callus derived from resistant and susceptible plants. The amount of callose formed in the cultured cells in response to the pathogen correlated with the degree of field resistance.
