In the marine green alga Ulva rigida C. Agardh, nitrate reductase (NR) is synergetically induced by blue light and nitrate. The present study examines the effect of blue light and a large NO 3 pulse (0.3 raM) on relevant variables of NO3-assimilation such as NO3-uptake, intracellular NO3-storage, NR

Nitrate-induced and phytochrome-modulated appearance of nitrate reductase (NR; EC 1.6.6.1) and nitrite reductase (NIR; EC 1.7.7.1) in the cotyledons of the mustard (Sinapis alba L.) seedling is strongly affected by externally supplied ammonium (NH2). In short-term experiments between 60 and 78 h aft
Nitrate reductase (NR, NADH:nitrate oxidoreductase, EC 1.6.6.1) from barley (Hordeum vulgate L. cv. Hassan) leaves was inactivated during a light-dark transition, losing approx. 50% of activity after 30 min of darkness. The dark inactivation was reversed by illumination of the seedlings, the kinetic
Molybdenum cofactor (MoCo) mutants of Neurospora crassa lack both NADPH-nitrate reductase and xanthine dehydrogenase activity. In vivo and in vitro studies to further characterize these mutants are now reported. The MoCo mutants nit-9A and nit-9B are capable of growing, albeit poorly, with nitrate a
