Nematodes failed to reach
maturity and did not initiate egg laying in resistant
roots. These results confirmed that the induction of
resistance is relatively late in this system. Typically in
pathogen resistance HR is closely associated with an
oxidative burst (OB) in infected tissue. The level of
reactive oxygen species release in both compatible
and incompatible reactions during early and late
stages of infection was also quantified. Following
a basal OB during early infection in both susceptible
