From: Jasmonate-mediated defence responses, unlike salicylate-mediated responses, are involved in the recovery of grapevine from bois noir disease

Fig. 10

Simplified model showing the salicylate-jasmonate interplay in the bois noir disease of grapevine. Plants react to phytoplasma infection by salicylate-mediated signalling, failing to activate or antagonising the jasmonate-mediated defence response, which leads to the development of bois noir symptoms and disease (left panel). On the other hand, activation of the entire jasmonate signalling pathway, together with counteraction of salicylate signalling and action, inhibits the development of symptoms and phytoplasma disease, leading to recovery from bois noir (right panel).
