Mutant kea4 kea5 kea6 is sensitive to low-K+ treatment. A and D, Growth of the mutants and overexpression lines at low K+. A, The mutants. D, The overexpression lines. Seedlings were grown on modified MS medium containing different levels of K+ (0.001–10 mm KCl). For the solidification of MS medium, 1% ultra-pure agarose was used (Pandey et al., 2007). Photographs were taken at 7 d under low-K+ treatment. Bars = 1 cm. B and E, Root length for the seedlings from A and D, respectively (mean ± se; n = 10 seedlings). C and F, Fresh weight for the seedlings from A and D, respectively (mean ± se; n = 30 seedlings). In B, C, E, and F, statistics by Student’s t test are shown: *, P < 0.05; **, P < 0.01; and ***, P < 0.001.
