Plants are constantlyinteracting with microorganisms. Many of them have the potential to causedisease, while many other may establish beneficial interactions where plants enhancetheir ability to incorporate important nutrients and improve disease resistance.During these interactions, plants must regulate the expression of thousands ofgenes, which ultimately triggers distinct hormonal signaling pathways andaffects the concentration of numerous metabolites. Transcriptomics andmetabolomics have played a pivotal role in identifying the genes andmetabolites involved in such responses, which has given crucial hints to refineour current strategies for plant protection and crop yield improvement.However, there is still a gap on our knowledge on many features thatdistinguish the interplay between plants and microorganisms. This chapter initiallydiscusses the contributions of these high-throughput technologies to theunderstanding of this field of research, and ends with future prospects in the searchfor interaction-specific biomarker genes and metabolites.
