TL;DR: Investigation of the potential of molecular genetic strategies to lower nitrate levels in burley tobaccos by overexpressing genes encoding key enzymes of the nitrogen‐assimilation pathway found only the expression of a constitutively active nitrate reductase (NR) dramatically decreased free nitrates levels in the leaves.
