Abstract: This invention relates to a method of producing a starch with unique functionality in plants through mutableness, and/or using biotechnology, and/or breeding practices. Further the invention relates to the starch from maize plants and/or other plants which produce starch storing organs which contain low amylose starch which has an amylose content between 1.5% and 15% and preferably between 1.5% and 10% and most preferably 1.5 and 8%. The invention includes starch extracted from such grain due to at least one mutation induced by ethyl methanesulfonate. Additionally, the invention uses a biotechnology approach involving controlling the activity of the granule bound starch synthase enzyme in starch storing organ. The invention includes the use of the starch for its cooking, paste, and gel properties.

Abstract: The invention relates to a method for changing the glucan chain lengths using fusion protein domains of various starch synthase enzymes in any starch or starch granule producing organism. The invention relates to identification of a GLucan ASSociation domain (herein after referred to as “GLASS” domain) of granule bound starch synthase (GBSS) used in combination with any other GLYcosyl TRransferase domain otherwise referred to as pfam00534-catalytic domain (herein after referred to as “GLYTR” domain) of one or more of any of the other starch synthase enzymes. The invention relates to identifying and using the new and surprising discovery that starch synthases are composed of at least two distinct functional domains herein after labeled as “GLASS” and “GLYTR”. More specifically, this invention relates to the genetic constructs that encode the fusions of the above domains and to the plants transformed with said constructs.
