Abstract excerpt

In the maize endosperm, the Opaque2 (O2) basic leucine zipper transcriptional activator regulates the expression of a subset of the zein seed storage protein gene family. Immunodetection of wild-type or mutant O2 polypeptides fractionated by SDS-PAGE resolved a closely spaced doublet migrating in...
