Plant Morphology of the lax2-1 Mutant.

(A) Mature panicles. The lax2-1 mutant has a sparse appearance due to the production of fewer branches and spikelets. WT, wild type.

(B) Enlarged view of boxes in (A).

(C) Whole plants at the vegetative growth stage. lax2-1 mutant has fewer tillers than the wild type.

(D) Culms of the wild type and lax2-1 after removal of the surrounding leaves. White arrowheads indicate the prophyll, which encloses the AM.

(E) Quantification of the number of spikelets in a panicle.

(F) Quantification of the number of PBs per panicle.

(G) Quantification of the number of lateral branches, which is the sum of the number of PBs, SBs, and spikelets in a panicle.

(H) Quantification of the number of tillers per plant.

Error bars in (E) to (H) represent sd. The sample size for (E) to (H) is n = 9.
