Dwarf and Reduced Cell Size Phenotypes of bin4.

(A) to (C) Twelve-day-old, light-grown seedlings.

(D) to (F) Differential interference contrast micrographs of 12-d-old cotyledon epidermis after clearing with chloral hydrate.

(G) to (I) Differential interference contrast micrographs of agar imprints of 3-d-old, dark-grown hypocotyls.

(J) and (K) Optical sections of 8-d-old, light-grown roots stained with propidium iodide (1 μg/mL).

(L) to (N) Twelve-day-old roots.

(O) to (Q) Scanning electron micrographs of mature trichomes.

(A), (D), (G), (J), (L), and (O) show wild-type Columbia ecotype; (B), (E), (H), (K), (M), and (P) show bin4-1; and (C), (F), (I), (N), and (Q) show bin4-2. Bars = 1 mm in (A) to (C), 50 μm in (D) to (I), 100 μm in (J) to (N), and 50 μm in (O) to (Q).
