Scholarcy highlights

  • Plants have evolved a diverse range of mechanisms to deal with changing environmental conditions
  • Assessing the function of specific genes can be achieved by gain and loss of function mutations using a wide range of techniques and by functional analysis of proteins and genetic elements
  • Only a small fraction of the metabolites exuded by plants from their roots into the rhizosphere have been investigated for their role in beneficial microbe recruitment and we are only just starting to understand these metabolic recruitment mechanisms
  • Owing to the high complexity of interactions influencing soil microbial communities, assessing the role played by specific species or genera in the plant stress response remains challenging
  • One could foresee knocking out quorum sensing functions or receptors of specific strains of bacteria using, for instance, sitedirected endonucleases to target specific microbial strains or their functions, allowing for eliminating one or more specific micro-organisms
  • Advances in the discovery of mechanisms underlying beneficial microbe recruitment will result in the development of new biotechnological approaches to engineer the plant–microbiome interaction, which will eventually result in a more sustainable agriculture
