N2 - An opaque mutation was identified that reduces γ-zein synthesis in maize endosperm. The mutation, opaque-15, causes a 2- to 3-fold reduction in γ- zein mRNA and protein synthesis and reduces the proportion of the 27-kDa γ- zein A gene transcript. Although the protein bodies in opaque-15 are similar in size and morphology compared to wild type, there are fewer of them in developing endosperm cells. The opaque-15 mutation maps near the telomere of chromosome 7L, coincident with an opaque-2 modifier locus. Based on its phenotype, opaque-15 appears to be a mutation of an opaque-2 modifier gene.
