Phenotypes of Wild-Type and bui1 Mature Plants.

(A) Wild-type (Zhejing 22; left) and bui1 (right) plants. Bar = 2 cm.

(B) Panicle exsertion of wild-type (left three) and bui1 (right three) plants. Bar = 2 cm.

(C) and (D) Longitudinal sections of the uppermost internodes of the wild type (C) and bui1 (D) at heading stage. The regions used for analysis are indicated with squares in (B). Bars = 100 μm.

(E) Panicles of the wild type (left) and bui1 (right) at the mature stage. Bar = 2 cm.

(F) to (H) Longitudinal sections of the uppermost internode regions (indicated with squares in [E]) of the wild type (F) and bui1 (G). Severely slanted cells of the same bui1 internode region are shown in (H). Bars = 50 μm.

(I) Panicle rachis of the wild type (left) and bui1 (right). Note the wavy rachis in bui1. Bar = 2 cm.

(J) Grains of the wild type (top) and bui1 (bottom). Bar = 0.5 cm.
