The Arabidopsis-microbiota interaction as a complex system: Multiple drivers that shape the outcomes of this plant–microbe interaction. A Drivers from the macro-organism plant perspective (from top to bottom): circadian and seasonal effects; ecotype; soil; plant developmental stage; biomolecules released by plants (i.e., root exudates); responses to the environment (i.e., biotic/abiotic stress responses) B Drivers from the microbial perspective: microbe-microbe interactions; microbial responses to biotic and abiotic stresses; biomolecules released by microorganisms and type of microorganisms (i.e., plant growth-promoting/protecting bacteria). C Future research needs
