| abstract |
The present invention provides a transformed plant that accumulates threonine, an amino acid, in leaves. A transformed plant is a genetic construct comprising an senescence-specific promoter isolated and operably linked to an aging-related gene of Arabidopsis thaliana to a coding sequence encoding a polypeptide having threonine-insensitive aspartate kinase activity. including. The senescence specific promoter (SAG) is selected from the group consisting of SAG12, SAG13, SAG101, SAG21 and SAG18 or a functional variant or fragment thereof. |
