许多报告表明，间作通常包括两个品种相邻种植，减少了微生物疾病的发生率。除了在田间水平操作的机制，如接种物稀释，最近有证据表明，以植物为中心的机制与确定的植物分子和途径也参与其中。首先，植物可以通过众所周知的诱导抗性机制触发邻近植物的抗性诱导。第二，一株植物在地上或地下产生的分子可以直接抑制病原体，或通过诱导邻近植物的植物免疫系统间接引发抗性。第三，对资源如光或营养的竞争可能间接改变植物免疫系统的表达。非亲/陌生识别和竞争的概念框架可能是有用的，以进一步研究的分子机制，作物保护种间植物混合物。
Many reports indicate that intercropping, which usually consists of growing two species next to each other, reduces the incidence of microbial diseases. Besides mechanisms operating at the field level, like inoculum dilution, there is recent evidence that plant-centered mechanisms with identified plant molecules and pathways are also involved. First, plants may trigger the induction of resistance in neighboring plants by the well-known mechanism of induced resistance. Second, molecules produced by one plant, either above- or belowground, can directly inhibit pathogens or indirectly trigger resistance through the induction of the plant immune system in neighboring plants. Third, competition for resources such as light or nutrients may indirectly modify the expression of the plant immune system. The conceptual frameworks of nonkin/stranger recognition and competition may be useful to further investigate the molecular mechanisms underlying crop protection in interspecific plant mixtures.
