Ribonuclease Activity in Normal and <i>Opaque-2</i> Mutant Endosperm of Maize

Abstract

Three strains of maize heterozygous for the opaque-2 mutant gene were self-pollinated to produce ears bearing both normal and opaque kernels. The ribonuclease activity of the opaque-2 endosperm was two to more than four times as high as the activity in the normal endosperm.
