Phytoremediation of Explosives using Transgenic Plants

In the past century, several explosive compounds have become the major soil contaminants causing health and economic challenges to the society. In the U.S. alone millions of hectares of land are contaminated by various forms of explosives. The two most dangerous explosives, 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5trinitro-1,3,5-triazine (Royal Demolition Explosive; RDX), are major enviro...

Transgenic plants for enhanced phytoremediation of toxic explosives.

Phytoremediation of organic pollutants, such as explosives, is often a slow and incomplete process, potentially leading to the accumulation of toxic metabolites that can be further introduced into the food chain. During the past decade, plants have been genetically modified to overcome the inherent limitations of plant detoxification capabilities, following a strategy similar to the development...

Phytoremediation of Metals Using Transgenic Plants

An ideal plant for environmental cleanup can be envisioned as one with high biomass production, combined with superior capacity for pollutant tolerance, accumulation, and/or degradation, depending on the type of pollutant and the phytoremediation technology of choice. With the use of genetic engineering, it is feasible to manipulate a plant’s capacity to tolerate, accumulate, and/or metabolize ...

Phytoremediation of selenium using transgenic plants.

Selenium (Se) is a micronutrient for many organisms but also toxic at higher concentrations. Both selenium deficiency and toxicity are serious problems worldwide. Owing to the similarity of selenium to sulfur, plants readily take up and assimilate selenate via sulfur transporters and enzymes and can even volatilize selenium. Selenium accumulating or volatilizing plants may be used for phytoreme...

Transgenic plants expressing antibodies: a model for phytoremediation.

The feasibility of using antibody expressing transgenic plants either to neutralize bioactive molecules in the rhizosphere, or to accumulate and concentrate the molecules in leaves has been demonstrated in a model system consisting of hydroponic Nicotiana plant cultures expressing a murine monoclonal IgG1. Two transgenic plant types were used; in the first, functional antibody was rhizosecreted...
