Ethylene is a local modulator of jasmonate-dependent phenolamide accumulation during Manduca sexta herbivory in Nicotiana attenuata

Résumé

Rapid reconfigurations of interconnected phytohormone signalling networks allow plants to tune their physiology to constantly varying ecological conditions. During insect herbivory, most of the induced changes in defence-related leaf metabolites are controlled by jasmonate (JA) signalling, which, in the wild tobacco Nicotiana attenuata, recruits MYB8, a transcription factor controlling the accumulation of phenolic-polyamine conjugates (phenolamides). In this and other plant species, herbivory also locally triggers ethylene (ET) production but the outcome of the JA-ET
