Kernel Phenotypes of the Wild Type and ocd1-1 Mutant.

(A) A self-pollinated ear segregating opaque mutants.

(B) and (C) Mature kernels of the wild type (B) and ocd1-1 (C) observed in a light box.

(D) and (E) Cross sections of mature wild-type (D) and ocd1-1 (E) kernels.

(F) and (G) Scanning electron micrographs of the peripheral area of the mature wild-type (F) and ocd1-1 (G) endosperm.

(H) Quantification of the starch content in the wild-type and ocd1-1 mature seeds.

(I) 100-kernel weight of wild type and ocd1-1.

Bars = 1 cm in (A), 0.5 cm in (B) to (E), and 20 µm in (F) and (G). Error bars show sd from three biological replicates. ***P < 0.001 as determined by Student’s t tests.
