Abstract
Abstract The degradation of organic pollutants in plants involves uptake and diffusion through the roots, trunk or leaves, transformation, accumulation and/or volatilization of soil- and aqueous-phase contaminants. 2,4,6-trinitrotoluene (TNT), the most widely used explosive, is toxic to a number of photosynthetic organisms, poses hazards to human health and pollutes the environment because it is recalcitrant to degradation. In this study, we investigated the nitroreductase gene from Citrobacter freundii in transgenic Arabidopsis thaliana plants. Transgenic plants showed a promising ability to tolerate, take up and detoxify TNT. Our results suggest that transgenic plants show higher potential for removing and transformation of TNT. The expression of nitroreductase in Arabidopsis could be useful for phytoremediation and could be explored for the effective cleanup of TNT-contaminated sites.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
