NO represses plant K+ uptake through its inhibition on AKT1 K+ channel. (A) Root K+ content in WT and sno1 mutant. (B) SNP effect on root K+ content in WT. (C) Root K+ content in nox1 mutant. (D) Phenotypes of akt1 mutant grown under 0 and 50 μM SNP for 15 d. (E) Relative root length of akt1 mutant in response to 0, 25, and 50 μM SNP treatment. Seeds were grown on SNP containing media for 15 d, and primary root length was measured. Relative root length is shown as a value relative to the root length on 0 μM SNP. Data shown are means ± SD, n = 35 seedlings. In A–C, 3-d-old seedlings were transferred to the new media for 15 d, and roots were collected for inductively coupled plasma–MS analysis. Data shown are means ± SD, n = 3.
