Sending Out an ROS

Local stresses, such as the damage caused by an insect on one leaf, can produce signals that are transmitted systemically to distant parts of the plant that are not directly injured or stressed. These signals help the plant acclimate to environmental stress or defend against pathogens. Miller et al. show that the gene RbohD, which encodes a plant NADPH oxidase that generates reactive oxygen species, is critical for rapid systemic signaling in response to wounding, heat, cold, intense light, or increased salinity.
