A hypothetical model of the influence of H₂O₂ on plant defense mechanisms associated with abiotic stresses. H₂O₂ treatment is capable of inducing abiotic stress tolerance through the development of a small oxidative burst. This burst subsequently activates a ROS-dependent signaling network, thereby enhancing the accumulation of latent defense proteins, such as ROS-scavenging enzymes and transcription factors (TFs), resulting in a primed state and an enhanced stress response (modified from Borges et al., 2014).
