Storage-protein hydrolysis and protein-body breakdown in germinatedZea mays L. seeds

M Torrent et al. Planta. 1989 Dec.

Abstract

Storage proteins of maize (Zea mays L.) were studied in germinated seeds, as were the proteins of protein bodies isolated from endosperms at different germination times. Major endosperm storage proteins were degraded in a sequential way, glutelin 2 being hydrolysed faster than zein 1. Immunocytochemical labelling of the different protein bodies using the antisera anti-glutelin 2 and anti-zein 1 indicates that the protein bodies were degraded by progressive hydrolysis from their surface. The digestion of glutelin 2 correlated with the disappearance of the protein-body membranes.
