Reggiani, R., Brambilla, I. and Bertani, A. 1985. Effect of exogenous nitrate on anaerobic metabolism in excised rice roots. I. Nitrate reduction and pyridine nucleotide pools.— J.exp. Bot 36:1193-1199. In apical segments of sterile rice roots, reduction of nitrate in the absence of oxygen is promoted by the presence of exogenous nitrate in the growth medium in the first 3 h of oxygen deficiency. Anaerobic treatment also increased the concentration of NADH. When nitrate was made available for reduction, smaller accumulations of NADH were observed. Oxidation of reduced nudeotides associated with the conversion of nitrate to nitrite is suggested as being responsible for this behaviour.
