Abstract excerpt
Among higher plants, soybean is unique in that biochemically it has been characterized as having two constitutive nitrate reductase (cNR) isoforms and one substrate-inducible nitrate reductase (iNR) isoform in leaves. All three NR isoforms are expressed in cv. Williams 82 while the nr1 mutant expresses only the iNR isoform. The genetic and molecular mechanisms for regulation of these isoforms have not been...
