The Phenotypes of the lew1 Mutant.

(A) Wild-type and lew1 mutant plants grown in soil. Left, lew1 (arrows point to wilted parts of leaves); right, the wild type.

(B) Comparison of root:shoot ratio. Data are means ± se (n = 41).

(C) Lp_r of wild-type and lew1 roots. The numbers in parentheses indicate the numbers of plants analyzed. Data are means ± se.

(D) and (E) Effects of aquaporin inhibitors on Lp_r of wild-type and lew1 plants: azide at 1 mM, 30 min (D) and mercury at 50 μM, 60 min (E). Data are means ± se. The numbers in parentheses indicate the numbers of plants analyzed.

(F) Structure of xylem in leaves (top row) and stems (bottom row) of wild-type and lew1 plants. Arrows point to xylem. Bars = 5 μm.

(G) Grafting experiments. Left, lew1 shoot with wild-type root; right, wild-type shoot with lew1 root.
