Kernel and Seedling Phenotypes.

(A) o5-Ref kernel phenotype. Mature kernels from a self-pollinated ear of an o5-Ref/+ heterozygote were photographed under reflected light (black background) or backlit by a transilluminator (white background).

(B) Seedling phenotypes. Kernels of the indicated genotype were planted in the greenhouse, and seedlings were photographed 7 d after emergence.

(C) o5-PS3038 kernel phenotype. A portion of a self-pollinated ear from an o5-PS3038/+ heterozygote is shown. Homozygous mutant kernels are variable in size, often shriveled, floury in texture, and carotenoid deficient.
