Subject:
secondary metabolites,   etc   ; microbiome; microorganisms;     Show all 3 Subjects
Abstract:
... Plants share their natural environment with numerous microorganisms, commensal as well as harmful. Plant fitness and performance are thus dependent on an efficient communication with such microbiota. The primary means of communication are metabolites exuded from roots, primarily diverse secondary metabolites. The exuded metabolites trigger changes in composition and function of plant associated mi ...
