摘要
植物抗性分为组成抗性和诱导抗性两种类型。组成抗性是植物的一种固有特性 ,取决于植物不同的基因型 ,始终存在于植物中并发挥作用 ;诱导抗性是一种类似于免疫反应的抗性现象 ,是植物的一种表型反应 ,只有在外源损伤的情况下才得以表现。本文主要综述了自 1997年以来植物诱导抗性的最新研究进展 ,包括对诱导抗性特性的重新认识及一些新的证据 ,对诱导抗性中能量分配与植物防御效益之间的风险平衡 ,信号 (特别是植食者的取食信号 )在诱导抗性中的作用 ,一些新发现的防御机制以及植食者的适应性等。对植物诱导抗性在生产上的应用前景作了简要的讨论 ,展望了这一领域的研究方向和尚需深入研究的问题。
Plant resistance can be classified into two types: constitutive and induced resistance. Plant constitutive resistance is characteristic of plant genotype and will have negative influences on herbivores ill all its life span. Induced resistance, which is a phenotypic response, happened when plants were attacked and damaged by herbivores and pathogens and is a kind of resistance similar to immune response as seen in animals. Since 1970s in the twentieth century, studies on induced resistance in plants had witnessed a great advances in moony aspects. The present paper reviewed the recent advances in this field, especially on those done after 1997, in order that it would not iterate the former reviews on this subject. These advances included in this paper are: some new understandings and new evidences for the induced plant resistance, the trade-orris between cost-allocation and benefits plant acquired from induced defense; roles of signals, especially herbivore feeding, in inducing plant resistance, some new induced defense mechanisms against herbivores in plants, and the adaptation of insect herbivores to induced plants. In the end of the paper, the perspective of practical application of induced resistance, the future development, and the questions still need to be studied in detail were discussed.
