The effect of recalcitrant soil and water pollutant 2,4,6-trinitrotoluen (TNT) on gene expression in Arabidopsis thaliana rosettes and roots was studied separately using microarrays. Seven-day exposure to TNT resulted in 170 up- and 122 down-regulated genes in the rosettes and 61 up- and 51 down-regulated genes in the roots (expression difference>1.5-fold; p[t test]<0.05). TNT concentration, 5 μg/ml, was selected according to the dose response analysis and study of TNT uptake from liquid media. Nitrate reductase 1, several glycosyltransferases and ABC transporters, sucrose–proton symporter 2, thioredoxindependent peroxidase 2, and gamma-glutamyltransferase are discussed for their potential to enhance detoxification and toleration capability of plants to TNT.
