Arabidopsis thaliana (Arabidopsis) Col-0 was inoculated with Phytophthora cinnamomi to assess the interaction and defence responses involved. Pathogen ingress and asexual reproduction occurred on root tissue but not leaf tissue. The colonisation of root tissue did not cause disease symptoms or plant death, indicating that Arabidopsis Col-0 was tolerant of the infection. The induction of several plant defence responses including the expression of defence-related genes were found, with differences displayed between inoculated root and leaf tissue. Arabidopsis defence-related gene mutant/over-expressing lines were also inoculated with P. cinnamomi but none of the lines tested exhibited a marked increase in susceptibility to the pathogen.
