多营养相互作用是塑造生物群落结构的强大力量。植物在其环境中遇到各种各样的生物体：其中一些相互作用是有益的（例如共生真菌和昆虫传粉者），而一些是有害的（例如食草昆虫和病原微生物）。地下和地上生物之间的多营养相互作用正受到越来越多的关注，因为它们可能影响植物对生物和非生物胁迫的防御（货车Dam等人，2003年）。植物防御可以是组成型的或诱导型的（Agrawal et al.，1999; Walling，2000），并且也可以是直接的（例如有毒化合物，如油菜科中的芥子油苷）或间接的。间接防御通常涉及产生对食草昆虫的天敌有吸引力的挥发性化学信息素（迪凯，1999）。这些化学信息素被称为synomone，以强调参与的合作伙伴的共同利益（Vet &迪凯，1992）。这些挥发物中的一些作为对特定食草动物攻击的特定反应而释放（参见Agrawal等人，1999年和其中的参考文献），这一特征被称为诱导的间接抗辩。一些研究表明，诱导挥发物的释放不仅限于受攻击的器官，而是通过系统激发子的循环涉及所有植物
Multitrophic interactions are powerful forces shaping the structure of living communities. Plants encounter a great diversity of organisms in their environment: some of these interactions are beneficial (eg symbiotic fungi and insect pollinators) while some are detrimental (eg herbivorous insects and pathogenic micro-organisms). Multitrophic interactions between below-ground and above-ground organisms are receiving increasing attention because they may influence plant defences against biotic and abiotic stresses (van Dam et al., 2003). Plant defences can be constitutive or induced (Agrawal et al., 1999; Walling, 2000), and may also be direct (eg toxic compounds like glucosinolates in Brassicaceae) or indirect. Indirect defences typically involve the production of volatile semiochemicals that are attractive towards natural enemies of herbivorous insects (Dicke, 1999). These semiochemicals have been referred to as synomones to stress the mutual benefit of the partners involved (Vet & Dicke, 1992). Some of these volatiles are released as a specific response to the attack of a specific herbivore (see Agrawal et al., 1999 and references therein), a feature termed induced indirect defence. Several studies show that the release of induced volatiles is not confined exclusively to the organ attacked but involves all the plant through the circulation of systemic elicitors
