Integration of omics data to unravel root microbiome recruitment

Highlights

• Plant-root microbiome recruitment is driven by genetics and the root exudate.

• Mapping approaches can shed light on the underlying genetics.

• Advanced multi-omics data integration approaches can improve insight into microbiome recruitment mechanisms.

• Improved use of the plant microbiome will result in a more sustainable agriculture.

The plant microbiome plays an essential role in supporting plant growth and health, but plant molecular mechanisms underlying its recruitment are still unclear. Multi-omics data integration methods can be used to unravel new signalling relationships. Here, we review the effects of plant genetics and root exudates on root microbiome recruitment, and discuss methodological advances in data integration approaches that can help us to better understand and optimise the crop–microbiome interaction for a more sustainable agriculture.
