Dynamic Root Exudate Chemistry and Microbial Substrate Preferences Drive Patterns in Rhizosphere Microbial Community Assembly
Show impact of plant exudates on soil microbiome.
- Changes in the root exudate chemistry during plant development and preferential consumption of specific exudate compounds by soil microorganisms is a key mechanism by which plants shape their rhizosphere microbiome.
- Provides a mechanistic underpinning of rhizosphere microbial community assembly and an attractive direction for the beneficial manipulation of the rhizosphere microbiome.
- Large-scale microbial isolation used to create a collection of relevant rhizosphere isolates.
- Microbial community analysis and comparative genomics used to define dynamics of microbial isolates in rhizosphere and identify microbial traits selected in the rhizosphere.
- Exometabolomics used to determine plant exudate composition and substrate uptake preferences of rhizosphere microorganisms.
