摘要: 系统获得性抗性(SAR)是一种因病原微生物初次侵染植物局部叶片而被激活的整株水平上的持久广谱抗性。在初次侵染部位快速产生的抗性信号, 可通过韧皮部传输到植物其它部位, 从而激活SAR。哌啶酸/N-羟基哌啶酸(Pip/NHP)作为新发现的移动信号分子, 在SAR信号通路中具有重要作用。该文综述了Pip/NHP的合成、转运以及对SAR调控作用的最新研究进展。

Abstract: Systemic acquired resistance (SAR) is a long-lasting broad-spectrum resistance at the whole plant level activated by the primary infection of pathogenic microorganisms at local leaves. The signals generated rapidly at the initial infection site can be transmitted to other parts of the plant through the phloem to activate SAR. Pipecolic acid (Pip) and N-hydroxy-pipecolic acid (NHP), as newly discovered mobile signal molecules, play important roles in SAR signaling pathway. Here, we mainly review the latest research progress in the synthesis, transportation of Pip/NHP and their regulation of SAR.

Key words: systemic acquired resistance, mobile signal, Pipecolic acid, N-hydroxy-pipecolic acid
