利用作物自身的防卫机制或免疫系统实现植物保护功能,是植保工作者长时期来梦寐以求、孜孜探索的目标。早在20世纪初就曾报道过,有的植物在被病原体(包括真菌、细菌、病毒及其代谢物等)侵染之后。似乎具备了抵抗病菌进一步侵害的能力。以后数十年中,又相继发表了若干有关的研究报告,表明植物中确实存在某种抗病免疫系统。30年代有人进而提出,植物中也可能存在像动物那样的获得性免疫能力,并且有不少论据支持此种提法。这便是以后经反复证实了的“植物受病原体侵染诱导而获得的系统抗病性能(induced systemic acquired resistance,ISR,也称做系统
The use of the crop’s own defense mechanism or the immune system to achieve plant protection is a goal that plant protection workers have long dreamed of and diligently explored. As early as the early 20th century, it was reported that some plants are infected by pathogens (including fungi, bacteria, viruses and their metabolites, etc.). Seems to have the ability to resist germs further violations. In the coming decades, several relevant studies have been published, indicating that there is indeed a disease-resistant immune system in plants. It was further suggested in the 1930s that animal-like adaptive immunity may also exist in plants, and there are many arguments in support of such a formulation. This is what has been repeatedly confirmed later by the ”systemic acquired resistance induced by pathogen infection (ISR, also known as system
