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.
期刊介绍:
The Annual Review of Phytopathology, established in 1963, covers major advancements in plant pathology, including plant disease diagnosis, pathogens, host-pathogen Interactions, epidemiology and ecology, breeding for resistance and plant disease management, and includes a special section on the development of concepts. The journal is now open access through Annual Reviews' Subscribe to Open program, with articles published under a CC BY license.
