Differentiating soil aggregate inoculum and host factors driving root microbiome assembly and function

Soil structure is vulnerable to intensive tillage practices, affecting water retention, erosion, and soil aggregate size distribution. Different soil aggregate sizes create a mosaic of microenvironments within soil, which house different communities of microbes. However, how these unique pockets of microbes colonize a root system has not been addressed. On the plant side, both root architecture and phytohormones mediate the selective recruitment of microbes to the root in response to soil microenvironment changes, including the microbes present.
