The rhizosphere of wetland plants is densely populated by many specialized organisms, which considerably influence its biogeochemical functioning. The roots protect themselvesagainst pests and control their rhizosphere organisms by bioactive chemicals, which oftenalso have medicinal properties. Anaerobic metabolites, alkaloids, phenolics, terpenoidsand steroids are bioactive chemicals abundant in roots and rhizospheres in wetlands.Bioactivities include allelopathy, growth regulation, extraorganismal enzymatic activities,metal manipulation by phytosiderophores and phytochelatines, various pest-control effectsand poisoning. Complex biological- biochemical interactions between roots, rhizosphereorganisms and the rhizosphere solution determine the overall biogeochemical processes inthe wetland rhizosphere and in the vegetated wetlands. To comprehend how wetlands reallyfunction, it is necessary to understand these interactions. Such understanding requiresfurther research.
