Summary

A sustainable approach to agriculture is required to meet the ever increasing demands in food supply caused by the growth of the human population. One area of interest in sustainable agriculture is the use of microorganisms’ abilities to increase plant yields. The use of metagenomics approaches have been crucial to understand the composition and the function of the plant microbiome. This chapter focuses on known microbiome gene-function links involved in: production/improved availability of plant nutrients; and plant disease suppression leading to improved plant growth. Genome sequencing of strain collections might provide a better screening tool for sets of plant growth promoting traits that could be readily detected in genomes. Future research should thus focus on further characterizing microbiome metagenomes, metatranscriptomes, metaproteomes, and community-scale metabolomes. This information will allow the construction of a holistic scheme of the microbiome functions in relation to its metagenome.
