Abstract

Cette invention concerne un procédé d'accroissement de la teneur en amidon du maïs par modulation de l'activité ou du niveau d'expression d'un ou plusieurs gènes du maïs dont les hexokinases. La variation allélique des gènes de maïs endogènes résultent de l'accroissement de la teneur en amidon. Un procédé et des compositions pour accroître et/ou moduler la teneur en amidon sont en outre décrits.
