Abstract

Benzoxazinoids (BXs) are secondary plant metabolites that provide innate defence against a plethora of pests and pathogens. They are identified both in monocots, namely grasses, and in several families of dicots. Among crops, BXs are best characterised in wheat, maize, and rye. These natural pesticides have inhibitory effects on weeds, insects, plant pathogenic fungi, bacteria, and nematodes. Besides, BXs demonstrated the ability to suppress production of mycotoxins, mitigate negative effects of microelement deficiency and toxicity and attract plant beneficial bacteria in the rhizosphere. Here, we summarise benefits and possible applications of these allelochemicals in pest control, which may be of special interest for production systems based on reduction or elimination of pesticides, such as integrated pest management or organic farming. In the light of it, we discuss possible limitations and risks of BX application that are worth considering. Finally, we refer to available germplasm with high BX level that can be exploited as a source of resistance in cereal breeding programmes.
苯并恶嗪类化合物——谷物中的保护性次生代谢物:作用与应用
苯并恶嗪类化合物(BXs)是次生植物代谢物,提供对大量害虫和病原体的先天防御。它们在单子叶植物,即禾本科和几个双子叶植物科中都有发现。在作物中,BXs在小麦、玉米和黑麦中表现最好。这些天然农药对杂草、昆虫、植物病原真菌、细菌和线虫有抑制作用。此外,BXs还能抑制真菌毒素的产生,减轻微量元素缺乏和毒性的负面影响,并在根际吸引植物有益菌。在这里,我们总结了这些化感化学物质在病虫害防治中的好处和可能的应用,这可能对基于减少或消除农药的生产系统特别感兴趣,例如病虫害综合管理或有机农业。鉴于此,我们讨论了BX应用程序可能存在的限制和风险,值得考虑。最后,我们提到了可以在谷物育种计划中作为抗性来源的高BX水平的可用种质。
