Abstract

Plants have coevolved together with the microbes that surround them and this assemblage of host and microbes functions as a discrete ecological unit called a holobiont. This review outlines plant-driven assembly of disease-suppressive microbiomes. Plants are colonized by microbes from seed, soil, and air but selectively shape the microbiome with root exudates, creating microenvironment hot spots where microbes thrive. Using plant immunity for gatekeeping and surveillance, host-plant genetic properties govern microbiome assembly and can confer adaptive advantages to the holobiont. These advantages manifest in disease-suppressive soils, where buildup of specific microbes inhibits the causal agent of disease, that typically develop after an initial disease outbreak. Based on disease-suppressive soils such as take-all decline, we developed a conceptual model of how plants in response to pathogen attack cry for help and recruit plant-protective microbes that confer increased resistance. Thereby, plants create a soilborne legacy that protects subsequent generations and forms disease-suppressive soils.

植物驱动的疾病抑制性土壤微生物组的组装。
植物与它们周围的微生物共同进化,这种宿主和微生物的集合体是一个离散的生态单位,称为整体生物体。本综述概述了植物驱动的疾病抑制微生物组的组装。植物从种子、土壤和空气中被微生物定殖,但根部渗出物会选择性地塑造微生物群,形成微生物繁衍生息的微环境热点。利用植物的免疫力进行把关和监控,宿主植物的遗传特性控制着微生物组的组合,并能赋予全生物体以适应性优势。这些优势体现在病害抑制性土壤中,在这种土壤中,特定微生物的积累抑制了病害的致病因子,这种土壤通常是在最初的病害爆发后形成的。基于病害抑制性土壤(如全株衰退),我们建立了一个概念模型,说明植物在应对病原体侵袭时如何呼救并招募能增强抗性的植物保护微生物。因此,植物在土壤中留下了保护后代的遗产,并形成了病害抑制土壤。
