Phenotypes of the tab1-1 Mutant.

(A) and (B) Shoot phenotypes of 2-month-old plants.

(C) and (D) Phenotypes of panicles.

(E) and (F) Complementation of tab1-1. Shown are a plant producing tillers (arrowheads) 2 months after regeneration (E) and a panicle with normal branches and spikelets (F). All six regenerated shoots with the TAB1 genomic sequence showed phenotypes similar to the wild type.

(G) and (H) Phenotypes of spikelets.

(I) and (J) Expression pattern of OSH1.

(K) and (L) Phenotypes of branches.

rg, rudimentary glume; sl, sterile lemma; sm, spikelet meristem. Bars in (A) to (F), (K), and (L) = 2 cm; bars in (G) and (H) = 1 mm; bars in (I) and (J) = 50 μm.
