Soil microbes can have large impacts on plant growth and physiology. However, how these impacts manifest at the transcriptional and metabolite level is not well understood, especially responses to complex mixtures of soil microbes. Here we characterize the response of Brassica rapa to a complex, naturally occurring soil inoculum that promotes shoot growth. We identify gene coexpression modules that both respond to microbial treatment and that are associated with leaf growth. Gene ontology and custom category analysis of these modules reveal root modules that are enriched for mineral nutrition (especially nitrogen, phosphorus, and iron) and leaf modules enriched for photosynthetic and cellular processes. The metabolite data shows an association of leaf length with nucleotide and amino acid levels, consistent with gene ontology terms observed in the leaf and perhaps reflecting the overall impact of growth promoting microbes on key nitrogen associated metabolic processes. Overall, this work provides an in depth characterization of the molecular responses of plants to plant growth promoting microbes <br> <br>
