Plants interact throughout their lives with environmental microorganisms. These interactions determine plant development, nutrition, and fitness in a dynamic and stressful environment, forming the basis for the holobiont concept in which plants and plant-associated microbes are not considered as independent entities but as a single evolutionary unit. A primary open question concerns whether holobiont structure is shaped by its microbial members or solely by the plant. Current knowledge of plant-microbe interactions argues that the establishment of symbiosis directly and indirectly conditions the plant-associated microbiome. We propose to define the impact of the symbiont on the plant microbiome as the 'symbiosis cascade effect', in which the symbionts and their plant host jointly shape the plant microbiome.
植物在其整个生命周期中与环境微生物相互作用。这些相互作用决定了植物在动态和充满压力的环境中的发育、营养和适应性，为“整体生物”概念奠定了基础，在这个概念中，植物和与植物相关的微生物不是被视为独立的实体，而是作为一个单一的进化单位。一个主要的悬而未决的问题是，整体生物的结构是由其微生物成员塑造的，还是仅仅由植物塑造的。目前对植物-微生物相互作用的认识认为，共生关系的建立直接和间接地影响了与植物相关的微生物组。我们建议将共生体对植物微生物组的影响定义为“共生级联效应”，其中共生体及其植物宿主共同塑造植物微生物组。
