Abstract

Soil remediation that revitalizes degraded or contaminated land while simultaneously contributing to biomass biofuel production and carbon sequestration is an attractive strategy to meet the food and energy requirements of the burgeoning world population. As a result, plant-based remediation approaches have been gaining in popularity. The drawbacks of phytoremediation, particularly those associated with low productivity and limitations to the use of contaminant-containing biomass, could be addressed through novel biotechnological approaches that harness recent advances in our understanding of chemical interactions between plants and microorganisms in the rhizosphere and within plant tissues. This opinion article highlights three promising approaches that provide environmental and economic benefits of bioremediation: transgenics, low-input 'designer' plants and nanotechnology.
