In plants, salicylic acid (SA) is a central immune signal that is involved in both local and systemic acquired resistance (SAR). In addition to SA, several other chemical signals are also involved in SAR and these include N-hydroxy-pipecolic acid (NHP), a newly discovered plant metabolite that plays a crucial role in SAR. Recent discoveries have led to a better understanding of the biosynthesis of SA and NHP and their signaling during plant defense responses. Here, I review the recent progress in role of SA and NHP in SAR. In addition, I discuss how these signals cooperate with other SAR-inducing chemicals to regulate SAR.
在植物中，水杨酸（SA）是一种核心免疫信号，参与局部和系统获得性抗性（SAR）。除了SA之外，其他几种化学信号也参与SAR，其中包括N-羟基哌啶酸（NHP），一种新发现的植物代谢产物，在SAR中起关键作用。最近的发现使人们对SA和NHP的生物合成及其在植物防御反应中的信号传导有了更好的理解。在此，我综述了SA和NHP在SAR中的作用的最新进展。此外，我还讨论了这些信号如何与其他诱导SAR的化学物质协同作用以调节SAR。
