blh12-3 blh14-1 Phenotypes during Tassel Development.

(A) Wild-type (left) and blh12-3 blh14-1 (right) shoot apices at 6 weeks old. Arrows and an arrowhead indicate axillary buds and an empty prophyll occasionally formed, respectively. Tassels can be seen at apices.

(B) Wild-type tassel at 6 weeks old.

(C) blh12-3 blh14-1 tassel at 6 weeks old.

(D) Top view of (B).

(E) Top view of (C).

(F) blh12-3 blh14-1 tassel at 7 weeks old.

(G) Wild-type tassel at 7 weeks old.

(H) KN1 immunostaining in the blh12-3 blh14-1 tassel at 6 weeks old.

(I) to (K) blh12-3 blh14-1 tassel at 8 (I), 9 (J), and 10 (K) weeks old. A box indicates the magnified area shown in the inset. Arrowheads indicate bract-like bulges.

Bars = 200 µm in (B) to (E), 500 µm in (F) to (H), 1 mm in (I) to (K), and 100 µm in the inset in (I).
