EFFECT OF THE HERBICIDE OXYFLUORFEN ON NITRATE REDUCTASE AND NITRATE CONTENT IN Zea mays L. SEEDLINGS [PDF]
Journal of Plant Production, 2012 Oxyfluorfen spraying resulted in distinct lowering of nitrate reductase with both doses of the herbicide (5 ppm and 15 ppm) and in both roots and leaves of maize seedlings throughout the run of the experiments.

Characteristics of a Nitrate Reductase in a Barley Mutant Deficient in NADH Nitrate Reductase [PDF]
Plant Physiology, 1982 A barley (Hordeum vulgare L.) mutant, nar1a (formerly Az12), deficient in NADH nitrate reductase activity is, nevertheless, capable of growth with nitrate as the sole nitrogen source. In an attempt to identify the mechanism(s) of nitrate reduction in the mutant, nitrate reductase from nar1a was characterized to determine whether the residual activity ...

Cloning and nitrate induction of nitrate reductase mRNA [PDF]
Proceedings of the National Academy of Sciences, 1986 Nitrate is the major source of nitrogen taken from the soil by higher plants but requires reduction to ammonia prior to incorporation into amino acids. The first enzyme in the reducing pathway is a nitrate-inducible enzyme, nitrate reductase (EC 1.6.6.1).

Nitrate Reductase mRNA Regulation in Nicotiana plumbaginifolia Nitrate Reductase-Deficient Mutants [PDF]
The Plant Cell, 1989 Light and substrate regulation of nitrate reductase (NR) expression were compared in wild type and mutant lines of Nicotiana plumbaginifolia. Mutants affected in the NR structural gene (nia) or in the biosynthesis of the NR molybdenum cofactor (cnx) were examined.
