在用坏死营养型病原体初始接种后，植物抵抗病原体攻击的潜力增强。不仅最初接种的组织，而且远距离器官如叶和根也变得具有抗性。这种免疫称为系统获得性抗性（SAR），Chester（4）首先在烟草中观察到烟草花叶病毒（TMV），Ross（50）和Kuc（28，29）的开创性工作进一步证明了这一点。致力于发现SAR期间的信号易位的努力揭示了水杨酸（SA）在激活导致SAR的防御机制中的核心作用（26，35，40）。开发了SA的功能类似物，例如2，6-二氯异烟酸（INA）或苯并[1，2，3]噻二唑-7-硫代甲酸S-甲酯（BTH或acibenzolar-S-methyl），其激活SA下游的抗性机制（16，26，35，40，57）。自从切斯特的观察以来，很少有人注意到诱导抗性在植物防御中的作用，特别是氨基酸的作用（29）。Kuc等人在1957年（31）和1959年（30）首次注意到，将D-苯丙氨酸、D-丙氨酸和DL-色氨酸注射到苹果叶片中可以提高对赤霉病的抗性，而不会影响体外致病病原体。早在1958年，货车安德尔（Van Andel）（60）就检测了50种氨基酸可诱导抗
The potential of a plant to resist attack by a pathogen is enhanced after an initial inoculation with a necrotrophic pathogen. Not only the initially inoculated tissue, but also the remote organs such as leaves and roots, become resistant. Such immunization, named systemic acquired resistance (SAR), was first observed by Chester (4) with Tobacco mosaic virus (TMV) in tobacco and was further demonstrated by the pioneering work of Ross (50) and Kuc (28, 29). Efforts devoted to discovering the signal translocating during SAR revealed (26, 35, 40) the central role of salicylic acid (SA) in activating the defense mechanisms leading to SAR. Functional analogs of SA, such as 2, 6-dichloroisonicotinic acid (INA) or benzo [1, 2, 3] thiadiazole-7-carbothionic acid S-methyl ester (BTH or acibenzolar-S-methyl), were developed which activate the resistance mechanisms downstream of SA (16, 26, 35, 40, 57). Since the observations of Chester, little attention was given to the role of induced resistance in general, and of amino acids in particular, in plant defense (29). Kuc et al. were the first to notice in 1957 (31) and 1959 (30) that D-phenylalanine, D-alanine, and DL-tryptophan injected into apple leaves increased resistance against scab without affecting the causal pathogen in vitro. As early as 1958, Van Andel (60) examined 50 amino acids for inducing resistance against
