The unseen rhizosphere root–soil–microbe interactions for crop production

The underground root-soil-microbe interactions are extremely complex, but vitally important for aboveground plant growth, health and fitness. The pressure to reduce our reliance on agrochemicals, and sustainable efforts to develop agriculture makes rhizosphere interactions' research a hotspot. Recent advances provide new insights about the signals, pathways, functions and mechanisms of these interactions. In this review, we provide an overview about recent progress in rhizosphere interaction networks in crops. We also discuss a holistic view of the root-soil-rhizomicrobiome interactions achieved through the advances of omics and bioinformatics technologies, and the potential strategies to manage the complex rhizosphere interactions for enhancing crop production.
