Zein Accumulation in Phenotypically Modified Lines of Opaque-2 Maize.

Phenotypically modified (i.e., containing regions of horny endosperm) selections of maize (Zea mays L.) A545o2 and B37o2 previously shown to have distinctive developmental patterns of ribonuclease activity did not show zein accumulation patterns different from unmodified (i.e., completely floury) versions of inbreds W64Ao2. In contrast, the zein pattern of modified B14o2 was different from unmodified B14o2. Thus, although phenotype, ribonuclease, and zein levels are all changed by opaque-2, it appears that these characteristics can be further modified independently.
