Abstract
The invention alters the physical characteristics of storage polyglucans including starch. Methods are provided to modify the polyglucan biosynthesis pathway by simultaneously altering the activity of a pullulanase debranching enzyme and the activity of another polypeptide in the polyglucan biosynthesis pathway. Compositions of the invention include transgenic plants and seeds having a modified polyglucan structure and/or content and elevated phytoglycogen levels. Additional compositions include a grain with increased energy availability for improved feed quality and industrial uses. Further compositions include a polyglucan with improved functional properties useful in a wide range of food and industrial applications.
