Abstract Barley (Hordeum vulgare L.) has two nitrate reductase (NR) isozymes, namely NADH-specific NR and NAD(P)H-bispecific NR. To determine the effect of NADH-specific NR deficiency on in vivo nitrate reduction and distribution of reduced N to shoots and roots, the 15N-incorporation model was applied to NADH-specific NR-deficient mutant (AzI2) seedlings of barley. The N-deprived seedlings were treated with a nutrient solution containing 2.3 mM N03 - and 0.2 mM N02 -, and were labeled with… CONTINUE READING
