Signalling between reactive oxygen species (ROS) and salicylic acid (SA)‐dependent programmed cell death (PCD) and defence responses is complex and much remains to be discovered. Recent reports have implicated myo ‐inositol (MI) in defence responses, but the relationships between MI, ROS and SA remain to be elucidated. In contrast, in the ΔnoxR strain ROS-scavenging proteins are induced upon injury, and those involved in ROS production are repressed. In plants and animals, the response to injury involves conserved mechanisms, including an increase in intracellular calcium and the activation of the calcium signaling machinery ( 19 ).
