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　for　biogeochemists.　©　2017,　Ecological　Society　of　China.　All　rights　reserved.
