Grapes for the Desert: Salt Stress Signaling in Vitis

Salinity does not only stress plants but also the biologists who sincerely try to discriminate its tangled elements. Adaptation to salinity is not provided by one single 'master-switch', but must have evolved from tuning the cross-talk of different regulatory circuits. A model for salt adaptation is developed, where efficient quenching of JA-signaling determines whether grapevine cells recognise the early stress signals as salinity related or defense-related.
