Among the regulatory mechanisms of systemic acquired resistance (SAR) in tomato, antagonistic interaction between salicylic acid (SA) and abscisic acid (ABA) signaling pathways was investigated. Treatment with 1,2-benzisothiazol-3(2H)-one1,1-dioxide (BIT) induced SAR in tomato thorough SA biosynthesis. Pretreatment of ABA suppressed BIT-induced SAR including SA accumulation, suggesting that ABA suppressed SAR by inhibiting SA biosynthesis.
在番茄系统获得性抗性（SAR）的调控机制中，研究了水杨酸（SA）和脱落酸（ABA）信号通路之间的拮抗相互作用。用1,2-苯并异噻唑-3（2H）-酮1,1-二氧化物（BIT）处理可通过SA生物合成诱导番茄产生SAR。ABA预处理抑制了BIT诱导的SAR，包括SA积累，这表明ABA通过抑制SA生物合成来抑制SAR。
