shr and scr are hypersensitive to high Glc but not salt and mannitol. A, Wild-type (WT), shr-2, and scr-4 seedlings on MS medium (top row) or MS medium containing 1 μm ABA (bottom row), 10 d after germination. B, The same three seedling types grown on MS medium containing 50, 100, and 150 mm NaCl, 2 weeks after germination. C, The same three seedling types grown on MS medium containing 50, 100, and 200 mm mannitol (Mann), 2 weeks after germination. D, The same three seedling types grown on MS medium (top row) or MS medium containing 4% Glc (bottom row), 10 d after germination. E and F, shr-2 and scr-1 as well as wild-type Col and Ws seedlings growing on MS medium with (F) or without (E) 4% Glc, 10 d after germination. The numbers represent root length in millimeters (means ± sd) from measurements of 15 seedlings. In A to D, only Col is shown as the wild type, as Col and Ws behaved similarly under the conditions tested.
