Rice_Rhizosphere_Soil_Microcosm Metagenome
This study investigates the effect of iron plaque on nitrogen fixation in the rice rhizosphere using a microcosm system consisting of excised rice roots. Two treatments were established: roots with iron plaque on the surface (experimental group) and roots without iron plaque (control group). A rhizosphere soil suspension was used as the inoculum, and glucose was added to simulate root exudates. The microcosms were incubated to evaluate how the presence of iron plaque influences rhizosphere nitrogen fixation activity. This work aims to elucidate the role of iron plaque in modulating microbial nitrogen fixation in the rice rhizosphere.
