Sampling Root-Associated Microbiome Communities of Maize ().

The soil microbiome of maize shapes its fitness, sustainability, and productivity. Accurately sampling maize's belowground microbial communities is important for identifying and characterizing these functions. Here, we describe a protocol to sample the maize rhizosphere (including the rhizoplane and endorhizosphere) and root zone (still influential but further from the root) in a form suitable for downstream analyses like culturing and DNA extractions. Although this protocol is written with as the focus, these methods can generally be applied to any plant with similar fibrous root systems.
