Title (EN) METHODS AND COMPOSITIONS FOR MAIZE STARCH REGULATION
(FR) PROCÉDÉS ET COMPOSITIONS DE RÉGULATION DE L'AMIDON DE MAÏS
Abstract:
(EN) Increasing maize kernel starch content by modulating the activity or expression level of one or more maize genes including maize hexokinases are provided. Allelic variation in endogenous maize genes result in increased starch content. Method and compositions to increase modulate starch content are provided.
(FR) 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.
