植物是复杂群落的成员，是地上和地下生物体之间的纽带。植物和土传微生物之间的联系经常发生，而且经常被发现有利于植物的健康。与根相关的微生物可能触发寄主植物的生理变化，从而影响植物与地上昆虫之间在几个营养水平上的相互作用。在地上，植物不断受到昆虫食草动物的攻击，并对地下微生物产生多种反应，这些反应也对地下微生物产生系统影响。直到最近，生态学和机械学的研究都主要集中在使用包括单一微生物和草食动物物种的简化系统来探索这些地下和地上的相互作用，这与自然发生的相互作用相去甚远。需要增加所研究系统的复杂性，以增加我们对微生物-植物-昆虫相互作用的了解，并从农业中使用非致病微生物获得更多好处。在这篇综述中，我们探讨了单个非致病微生物物种或地下微生物群落的定殖如何影响植物的生长和防御，以及这如何影响植物与不同营养水平的地上昆虫的相互作用。此外，我们还回顾了不同取食集团的昆虫对叶片食草性昆虫的反应如何影响植物与非致病土壤微生物的相互作用。讨论了植物激素在协调植物生长、植物对叶食草动物的防御、同时与非致病土壤微生物建立联系中的作用。
Plants are members of complex communities and function as a link between above- and below-ground organisms. Associations between plants and soil-borne microbes commonly occur and have often been found beneficial for plant fitness. Root-associated microbes may trigger physiological changes in the host plant that influence interactions between plants and aboveground insects at several trophic levels. Aboveground, plants are under continuous attack by insect herbivores and mount multiple responses that also have systemic effects on belowground microbes. Until recently, both ecological and mechanistic studies have mostly focused on exploring these below- and above-ground interactions using simplified systems involving both single microbe and herbivore species, which is far from the naturally occurring interactions. Increasing the complexity of the systems studied is required to increase our understanding of microbe–plant–insect interactions and to gain more benefit from the use of non-pathogenic microbes in agriculture. In this review, we explore how colonization by either single non-pathogenic microbe species or a community of such microbes belowground affects plant growth and defense and how this affects the interactions of plants with aboveground insects at different trophic levels. Moreover, we review how plant responses to foliar herbivory by insects belonging to different feeding guilds affect interactions of plants with non-pathogenic soil-borne microbes. The role of phytohormones in coordinating plant growth, plant defenses against foliar herbivores while simultaneously establishing associations with non-pathogenic soil microbes is discussed.
