Improving Micronutrients Acquisition Efficiency Through Transgenic Technology
Advancements made in recent years in the area of recombinant DNA technology have provided an altogether new dimension to agricultural research. For instance, engineering plants with improved nutrient uptake may help in sustainable agriculture in the twenty-first century. Molecular genetic tools have given the researcher the possibility to identify key regulatory steps in the acquisition of nutrients by plants. There are now convincing evidences that the genes coding for several target traits, mainly the transporters and other mechanisms for nutrients acquisition opens up several options to improve nutrient uptake and utilization in soils with low fertility. The transfer of the corresponding genes to agriculturally important crops might therefore allow to increase their nutrient uptake capacity.

Phytoremediation - Use of green plants to remove pollutants
The major challenge facing society in the twenty-first centaury is to feed and provide for increasing numbers of people while protecting human health and the environment. Over the last centaury, increasingly wide spread heavy metal pollution and organic contaminants have caused many areas to become non-arable and hazardous for both wildlife and human populations. Industrial waste products account for most heavy metals pollution, although sewage and household waste also introduce substantial levels of toxic metals into the environment. Contaminated soils and waters pose a major environmental human problem. Physical, chemical and biological processes are already being used to remediate contaminated soil, but these techniques can grossly disrupt the polluted site and are expensive. This problem may be solved by the emerging phytoremediation technology that employs the use of higher plants for the cleanup of contaminated environments.
