Abstract
The selection of the microbiota by plants involves a large number of traits including the physicochemical properties of the soil, the composition of the soil microbiota which is the reservoir, the root architecture, the composition of the root cell wall, and the composition of root exudates which can act as nutrients and signalling molecules. Any modification of these traits can lead to a modulation of the microbiota hosted by the plant and could therefore have an impact on plant health. Newly introduced or modified genes into plants which are involved in new metabolic pathways or in the response to pests may modify root exudates’ quality and quantity and hence have an impact on plant microbiome diversity and function. This chapter reviews recent studies and emerging trends on how the modification of root exudates could impact the plant microbiome.
