Elicitor Specific Mechanisms of Defence Priming in Oak Seedlings Against Powdery Mildew.

Defence priming sensitises plant defences to enable a faster and/or stronger response to subsequent stress. Various chemicals can trigger priming; however, the response remains unexplored in oak. Here, we characterise salicylic acid (SA)-, jasmonic acid (JA)-, and β-aminobutyric acid (BABA)-induced priming of oak seedlings against the causal agent of powdery mildew (Erysiphe alphitoides, PM).
