New weapons explosive exhibits persistent toxicity in plants
Explosives are widespread, toxic and persistent environmental pollutants. 2,4-Dinitroanisole (DNAN) is being phased in to replace 2,4,6-trinitrotoluene (TNT) in munitions. Here we demonstrate that only low levels of DNAN are detoxified in Arabidopsis, leaving it to remain as a substrate for monodehydroascorbate reductase 6 mediated chronic phytotoxicity. Enhancing the potential for environmental toxicity, DNAN is readily transported to the aerial tissues exposing this toxin to herbivores and the wider food chain.
