Characterization of the ahp1,2,3,4,5 Quintuple Mutant.

(A) Seven-day-old seedlings of the wild type (Col-0; left), ahp1,2-1,3,4,5 (middle), and ahp1,2-2,3,4,5 (right). Bar = 5 mm.

(B) Four-week-old seedlings of the wild type (Col-0; left), ahp1,2-1,3,4,5 (middle), and ahp1,2-2,3,4,5 (right; denoted by an arrow). Bar = 20 mm.

(C) An enlarged view of an ahp1,2-2,3,4,5 seedling grown in soil for 4 weeks. Bar = 2 mm.

(D) to (F) The cellular phenotype of the ahp1,2-1,3,4,5 leaf. Leaves of the wild type and ahp1,2-1,3,4,5 (ahp2-1) were analyzed as described in Figure 3. Asterisks indicate statistically significant differences compared with wild-type plants (Student's t test, P < 0.01).

(D) The leaf blade area.

(E) Average size of abaxial epidermal cells.

(F) The number of abaxial epidermal cells.
