水杨酸(SA)是一种重要的植物激素,在许多生理反应中起着至关重要的作用,包括植物防御。在过去的二十年里,SA介导的生物合成、转运、感知和信号转导等方面取得了许多突破。这些发现表明SA在局部和系统防御反应中起着关键作用。系统获得性抗性(SAR)是一种这样的SA依赖性反应。SAR是一种长距离信号传导机制,可在整个植物中对继发感染提供广谱和持久的抗性。这种独特的特性使SAR成为作物生产中非常理想的性状。本文综述了SA在SAR中作用的最新进展,并讨论了其与其他SAR诱导剂的关系。
Salicylic acid (SA) is an important phytohormone that plays a vital role in a number of physiological responses, including plant defense. The last two decades have witnessed a number of breakthroughs related to biosynthesis, transport, perception and signaling mediated by SA. These findings demonstrate that SA plays a crictical role in both local and systemic defense responses. Systemic acquired resistance (SAR) is one such SA-dependent response. SAR is a long distance signaling mechanism that provides broad spectrum and long-lasting resistance to secondary infections throughout the plant. This unique feature makes SAR a highly desirable trait in crop production. This review summarizes the recent advances in the role of SA in SAR and discusses its relationship to other SAR inducers.
