GENETICALLY ENGINEERED MODIFICATION OF POTATO FOR PRODUCING AMYLOPECTIN STARCH

Title:

GENETICALLY ENGINEERED MODIFICATION OF POTATO FOR PRODUCING AMYLOPECTIN STARCH

Document Type and Number:

Japanese Patent JP2004097219

Kind Code:

A

Abstract:

To provide a method for suppressing formation of amylose in a tuber of potato.

Genetically engineered modification of potato that inhibits formation of an amylose starch is described. Three fragments inserted into a potato genome in an antisense direction are also described. Further, an antisense structure, a gene and a vector having the above antisense fragments are described. Furthermore, a gene promoter encoding the formation of a granule-bound starch synthase and its own gene are described. Also, a cell, a vegetable material, a tuber, a minute tuber and a seed having the above antisense fragment are described. Finally, just as natural or derived amylopectin starch originated from the potato modified by the genetically engineered method and the method for inhibiting the amylose formation in potato are described.
