| abstract |
The present invention relates to an isolated polypeptide having a signal targeting alpha-amylase activity and / or starch binding activity and / or plastids and an isolated polynucleotide encoding the polypeptide. The present invention also relates to DNA constructs, vectors and host cells that incorporate polynucleotide sequences, methods for modulating starch content in plants, particularly plastids, and modifying plastid-specific starches. Applicants have identified a class of alpha-amylases with signals targeting plastids and starch binding activity. |
