The accumulation of alpha-zein in transgenic tobacco endosperm is stabilized by co-expression of beta-zein

The cysteine-poor alpha-zein is the major prolamin storage protein fraction in maize endosperm and is localized in the interior of protein bodies with delta-zein, whereas the hydrophobic cysteine-rich beta- and gamma-zein are found on the exterior of the PB. In transgenic tobacco endosperm expressin...
