目前出现的一些植物病害的替代防治策略是基于抗性诱导剂的使用。本综述重点介绍了通过启动机制诱导抗性的天然化合物的特性研究进展。这些物质包括维生素、壳聚糖、低聚半乳糖醛酸苷、挥发性有机化合物、杜鹃花和吡喃甲酸等。总体而言，除了提供符合环境法规的新型疾病控制策略外，天然引发剂还是帮助解开诱导抗性(IR)现象背后复杂机制的宝贵工具。这篇综述中给出的数据反映了这些天然植物诱导剂的研究取得的新贡献，特别是己酸(HX)，本文建议将其作为该研究领域的模型工具。HX是一种有效的天然引发剂，在广泛的寄主植物和病原体中都被证明是有效的。它可以通过诱导蛋白沉积、水杨酸(SA)和茉莉酸(JA)途径，早期激活广谱防御系统。之后，它可以根据病原体的生活方式启动病原体特异性反应。有趣的是，HX启动氧化还原相关基因以产生抗氧化保护作用，这可能是限制坏死菌感染的关键。我们的HX-IR研究结果也有力地表明，它是一种有吸引力的工具，用于表征植物警报状态的分子特征，此外它还是一种天然化合物。
Some alternative control strategies of currently emerging plant diseases are based on the use of resistance inducers. This review highlights the recent advances made in the characterization of natural compounds that induce resistance by a priming mechanism. These include vitamins, chitosans, oligogalacturonides, volatile organic compounds, azelaic and pipecolic acid, among others. Overall, other than providing novel disease control strategies that meet environmental regulations, natural priming agents are valuable tools to help unravel the complex mechanisms underlying the induced resistance (IR) phenomenon. The data presented in this review reflect the novel contributions made from studying these natural plant inducers, with special emphasis placed on hexanoic acid (Hx), proposed herein as a model tool for this research field. Hx is a potent natural priming agent of proven efficiency in a wide range of host plants and pathogens. It can early activate broad-spectrum defenses by inducing callose deposition and the salicylic acid (SA) and jasmonic acid (JA) pathways. Later it can prime pathogen-specific responses according to the pathogen’s lifestyle. Interestingly, Hx primes redox-related genes to produce an anti-oxidant protective effect, which might be critical for limiting the infection of necrotrophs. Our Hx-IR findings also strongly suggest that it is an attractive tool for the molecular characterization of the plant alarmed state, with the added advantage of it being a natural compound.
