RICE OSAGPL1 GENE, OSAGPL3 GENE, OR OSAGPL4 GENE AND PLANT TRANSFORMED WITH THE SAME

摘要

Each of genes, (OsAGP)L1, OsAGPL3 and OsAGPL4, regarding an ADP-glucose pyrophosphorylase derived from Oryza sativa L. which are three large subunit proteins for controlling the synthesis of starch is provided which is specifically located at a plastid in Oryza sativa L. cell. A gene encoding a large subunit of OsAGP is selected from the group consisting of an OsAGPL3 gene having a sequence of SEQ ID : NO. 2 and an OsAGPL4 gene having a sequence of SEQ ID : NO. 3, wherein the coding protein of each of the gene is specifically located at a plastid in a rice cell. A transgenic Oryza sativa L. plant is transformed by a recombinant plant expression vector including the gene. A method for preparing a transgenic Oryza sativa L. plant comprises the steps of: (a) transforming an Oryza sativa L. plant cell using the vector; and (b) redifferentiating the Oryza sativa L. plant cell into an Oryza sativa L. plant. A method for targeting a protein selected from the group consisting of OsAGPL3 and OsAGPL4 into a specific position in an Oryza sativa L. cell comprises a step of transforming an Oryza sativa L. plant cell using the vector, wherein the specific location is a plastid. A starch is isolated from the transgenic Oryza sativa L. plant prepared by the method.
