The volatile metabolome of grapevine roots: First insights into the metabolic response upon phylloxera attack

► 38 volatiles identified in healthy and phylloxera-infested grapevine root samples by GC-MS. ► Fourteen differentially expressed metabolites in phylloxera-infested grapevine root tips. ► Root infestation by phylloxera is associated with defence response in grapevine. ► MEV/alt. IPP-, phenylpropanoid- and LOX pathways are affected upon phylloxera attack.
