Figure 1.

Schematic representation of AtNRT2.1 and AtNRT2.2 genes with T-DNA insertions. Gray boxes indicate locations of promoters; black and white boxes represent exons and untranslated regions, respectively. In Atnrt2.1-nrt2.2 mutants (Salk_035429), the T-DNA insertion has deleted all of AtNRT2.2 and part of the AtNRT2.1 gene; in Atnrt2.1 mutants (Salk_141712), the T-DNA insertion is at 236 bp before the putative start codon; in Atnrt2.2 mutants (Salk_043543), the T-DNA insertion is 15 bp upstream of the putative start codon. The diagram is not drawn to scale.
