nakr1-1 Na, K, and Rb Accumulation Phenotypes and Root Growth Defects Were Complemented by a NaKR1 Whole-Gene Construct.

(A) to (C) Concentrations of shoot Na⁺, K⁺, and Rb⁺ in Col-0, nakr1-1, and complemented lines 1 and 3 (T2 generation) are presented as mean ± sd (n = 12). Student’s t test was performed, and the different letters indicate significant difference with P < 0.05. Plant growth, sample collection, and ICP-MS analysis were according to Lahner et al. (2003).

(D) Eight day-old seedlings grown vertically on ATS media. From left to right are two complementation lines, nakr1-1, and Col-0. Note that nakr1-1 had reduced primary root growth.
