Root signalling in the formation of the rhizosphere microbiome
A considerable part of plants’ most valuable elements such as carbon and nitrogen are secreted by roots into the soil in the form of chemically rich exudates. This is considered the chemical language of plants in their underground communication with billions of microorganisms. But how do plants control and manipulate root metabolism and exudation in time and space in their favour? The EU-funded SIREM project envisages deciphering the recently discovered process of Systemic Induced Root Exudation of Metabolites. SIREM is a fundamental characteristic of rhizosphere interactions responsible for the maintenance of plant fitness. The project will anatomise the SIREM signalling pathways, discover the exudation mechanism and its genetic control, and establish the role of SIREM signalling and exudation metabolites in the formation of the rhizosphere microbiome.
