A wild-type line and 14 nitrate reductase - deficient mutant lines were tested for the presence of nitrate reductase partial activities, and for nitrite reductase and xanthine dehydrogenase activity. Three lines carrying the gene cnx simultaneously lacked NADH, reduced flavin adenine dinucleotide (FADH2) and reduced benzyl viologen nitrate reductase and xanthine dehydrogenase activities, but retained the nitrate reductase associated NADH-cytochrome c reductase activity.
