We have abundant knowledge on drought responses of plants or soil microorganisms individually. However, there is a severe lack of knowledge regarding interactions in the plant-soil-microbiome continuum, and specifically root-soil interface traits including the role of root hairs. Here, we investigated how water limitation propagates in a plant-soil-microbiome system upon stopping irrigation. We used two Zea mays genotypes (rth3 and its isogenic wildtype B73), differing in root hair formation, to elucidate the effect of rhizosphere extension under water limitation.
