Major alterations of the regulation of root NO(3)(-) uptake are associated with the mutation of Nrt2.1 and Nrt2.2 genes in Arabidopsis.

Abstract excerpt

The role of AtNrt2.1 and AtNrt2.2 genes, encoding putative NO(3)(-) transporters in Arabidopsis, in the regulation of high-affinity NO(3)(-) uptake has been investigated in the atnrt2 mutant, where these two genes are deleted. Our initial analysis of the atnrt2 mutant (S. Filleur, M.F. Dorbe, M. Cerezo, M. Orsel, F. Granier, A. Gojon, F. Daniel-Vedele [2001] FEBS Lett 489: 220-224) demonstrated that root NO(3)(-)...
