The genes involved in the metabolism of chemical compounds can be isolated from various organisms, including bacteria, fungi. Many transgenic plants with new characteristics due to expression of genes from microorganisms, yeasts, mouse, or even human have been reported in scientific. Candidate plants for genetic engineering for phytoremediation should be a high biomass plant with either short or long duration trees, which should have inherent capability for phytoremediation. Transgenic plants for phytoremediation of herbicides sciencedirect. Phytoremediation uses wild or genetically modified plants gmps to extract a wide range of heavy metals and organic pollutants from the soil. Specific genes in transgenic plants increase the metabolism, accumulation and uptake of definite pollutants 94,100. The candidate plants should be amicable for genetic transformation. Phytoremediation of herbicides using transgenic plants.

Enhanced phytoremediation of volatile environmental. Transgenic plants produced for metabolizing herbicides and longpersisting pollutants can be used for phytoremediation of foreign chemicals in contaminated soil and water. Phytoremediation, the use of plants and their associated microbes to remedy contaminated soils, sediments, and groundwater, is emerging as a costeffective and environmentally friendly technology. Materials and methods phytoremediation is a method which green plants use for cleaning up contaminated hazardous wastes sites. It entails the use of plants for uptake, sequestration, detoxification or volatilization of inorganic and organic pollutants from soils, water, sediments and possibly air. Transgenic plants exhibiting biodegradation capabilities of microorganisms bring the promise of an efficient and environmentalfriendly. A recent publication by doty and colleagues describes the development of transgenic poplars populus overexpressing a mammalian cytochrome p450, a.

An approach for impact assessment of transgenic plants on. Application of floating aquatic plants in phytoremediation of. Phytoremediation is the use of plants to clean up environmental pollution. Phytoremediation is a green, sustainable and promising solution to problems of environmental contamination. Development of transgenic plants for enhanced phytoremediation of metals has also been successful 11, including plants have been developed to detoxify and remove mercury 12, lead and cadmium , and selenium from polluted soils 14. Initial experiments with transgenic plants have shown that they are indeed efficient in drawing metals from heavily contaminated soils. Due in large part to its aesthetic appeal, this technology has gained increasing attention over the past 10 years. Figure 2 proportion of publications on transgenic plants for phytoremediation classified according to. However, detoxification of organic pollutants by plants is often slow, leading to the accumulation of toxic compounds that could be later released into the environment.
