Root bioturbation plays an important role in increasing the rates of dissimilatory iron reduction in the rhizosphere of wetland plants. Previous research has focused mainly on the differences in dissimilatory iron reduction among various macro-habitats. Recently, more attention has been drawn to iron biogeochemical behaviors in the microcosmic rhizosphere. This paper lists the rates of dissimilatory iron reduction in the rhizosphere of several wetland plants, introduces the mechanism of root bioturbation and its effects on iron reduction, clarifies the influence of root bioturbation on the competition between dissimilatory iron reduction and other organic matter degradation pathways, highlights the response of dissimilatory iron reduction to root bioturbation dynamics and heterogeneity, and provides a schematic illustration of rhizospheric dissimilatory iron reduction in wetland plants. The purpose of this review is to attract more attention to the effect of root bioturbation on dissimilatory iron reduction, and hopefully offers useful references for biogeochemists.
