Abiotic stress induces nitrate (NO3 (-)) allocation to roots, which increases stress tolerance in plants. NRT1.1 is broadly involved in abiotic stress tolerance in plants, but the relationship between NRT1.1 and NO3 (-) allocation under stress conditions is unclear. In this study, we found that Arabidopsis wild-type Col-0 was more cadmium (Cd(2+))-tolerant than the nrt1.1 mutant at 20 muM CdCl2. Cd(2+) exposure repressed NRT1.5 but upregulated NRT1.8 in roots of Col-0 plants, resulting in increased NO3 (-) allocation to roots and higher [NO3 (-)] root-to-shoot (R:S) ratios. Interestingly, NITR...
