The holobiont is composed by the plant and its microbiome. In a similar way to ecological systems of higher organisms, the holobiont shows interdependent and complex dynamics [1,2]. While plants originate from seeds, the microbiome has a multitude of sources. The assemblage of these communities depends on the interaction between the emerging seedling and its surrounding environment, with soil being the main source. These microbial communities are controlled by the plant through different strategies, such as the specific profile of root exudates and its immune system. Despite this control, the microbiome is still able to adapt and thrive. The molecular knowledge behind these interactions and microbial '-omic' technologies are developing to the point of enabling holobiont engineering. For a long time microorganisms were in the background of plant biology but new multidisciplinary approaches have led to an appreciation of the importance of the holobiont, where plants and microbes are interdependent.
生物体由植物及其微生物组构成。与高等生物的生态系统类似，生物体表现出相互依存和复杂的动态关系[1,2]。虽然植物起源于种子，但微生物组有多种来源。这些群落的组合取决于幼苗的出现及其周围环境的相互作用，而土壤是主要来源。这些微生物群落通过不同的策略受到植物的控制，例如根分泌物的特定谱及其免疫系统。尽管受到这种控制，微生物组仍然能够适应和茁壮成长。这些相互作用背后的分子知识和微生物组学技术正在发展，使生物体工程成为可能。长期以来，微生物在植物生物学中处于次要地位，但新的多学科方法使人们认识到生物体的重要性，其中植物和微生物是相互依存的。
