Nucleic acid molecules are described encoding a starch granule-bound protein from maize as well as methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch. Moreover, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.

Nucleic acid molecules from maize and their use for the production of modified starch

Nucleic acid molecules are described, which encode debranching enzymes from , as well as transgenic plant cells and plants in which an amylopectin with modified properties is synthesized due to the expression of a debranching enzyme from or due to the inhibition of such an endogeneous debranching enzyme activity.

Nucleic acid molecules coding for debranching enzymes from maize

The invention describes DNA molecules which code for plant proteins having the biological activity of a debranching enzyme. Furthermore described are transgenic plant cells and plants having reduced or increased debranching enzyme activity, as well as modified starch isolatable from the cells and plants.

DNA molecules coding for debranching enzymes derived from plants

Nucleic acid molecules are described, which encode debranching enzymes from potato, as well as transgenic plant cells and plants in which an amylopectin with modified properties is synthesized due to the expression of a debranching enzyme from potato or due to the inhibition of such an endogeneous debranching enzyme activity.

Nucleic acid molecules coding for debranching enzymes from potato

The present invention relates to DNA sequences which, on the codogenic strand, code plant debranching enzymes whose transcripts formed in transgenic plants code new proteins with the enzymatic activity of debranching enzymes which in transgenic plants reduce the degree of branching of amylopectin starch. The invention also relates to DNA sequences which on the codogenic strand code plant debranching enzymes whose transcripts formed in transgenic plants prevent the synthesis of proteins with the enzymatic activity of debranching enzymes, which in transgenic plants increases the degree of branching of amylopectin starch, and also to recombinant plasmids on which these DNA sequences are localized and which can be introduced into plant cells and plants.

Debranching enzymes and DNA sequences coding them, suitable for changing the degree of branching of amylopectin starch in plants

Nucleic acid molecules are described, which encode debranching enzymes from maize, as well as transgenic plant cells and plants in which an amylopectin with modified properties is synthesized due to the expression of a debranching enzyme from maize or due to the inhibition of such an endogeneous debranching enzyme activity.
