Arabidopsis keg Mutants Are Defective in Cell Expansion.

(A) Five-day-old seedlings grown on half-strength MS. Col-0, Columbia-0. Bars = 5 mm.

(B) Cotyledon epidermal cells of 5-d-old seedlings expressing the PM marker BRI1-sYFP. Bars = 25 μm.

(C) Root tips of 5-d-old seedlings. Bars = 100 μm.

(D) to (G) Scanning electron micrographs of hypocotyls of 5-d-old seedlings grown in the presence of 1% Suc. Bars = 100 μm in (D) and (F) and 10 μm in (E) and (G).

(H) Seven-day-old etiolated seedlings. Bar = 5 mm.

(I) Hypocotyl length of 7-d-old etiolated seedlings. Data represent means ± sd (n = 30).

(J) Hypocotyl cell number of 7-d-old etiolated seedlings. Data represent means ± sd (n = 30).
