The incorporation of the gene for cyanamide hydratase can make transgenic tobacco plants resistant to the herbicide cyanamide H 2 NCN. The herbicide is degraded by the expressed gene to the physiologically harmless urea H 2 NCONH 2 . In the presence of the ubiquitous plant enzyme urease, which degrades urea, the hydrolysis product NH 4 +can, in fact, serve as nitrogen source. The efficiency of this new approach is impressively demonstrated.
