Abiotic stress induces nitrate (NO 3 - ) 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 NO 3 - 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 μM CdCl 2 . Cd 2+ exposure repressed NRT1.5 but upregulated NRT1.8 in roots of Col-0 plants, resulting in increased NO 3 - allocation to roots and higher [NO 3 - ...
