A METHOD ENHANCING THE RESISTANCE AGAINST PLANT DISEASES BY THE OVER-EXPRESSION OF OSWRKY6 GENE, OSWRKY6 GENE HAVING THIS ACTIVITY, A EXPRESSION VECTOR CONTAINING THE SAME GENE AND A TRANSGENIC PLANT CELL

A method for enhancing the resistance against plant diseases and a transformant over-expressing an OsWRKY6 gene are provided to be utilized as a molecular breeding material for developing a disease-resistant crop by having excellent bacterial blight resistance in rice as well as resistance against wide range of pathogenic bacteria range resistance, be used for various crops because other crops preserve well disease defense mechanism relating to the OsWRKY6 gene and decrease the use of pesticide due to the disease resistant species breeding, thereby improving the productivity and supplying safe agricultural products. A method for enhancing the resistance against plant diseases comprises the steps of: (a) preparing an expression vector pB2GW7-OsWRKY6 having a cleavage map depicted in Fig. 4b including an OsWRKY6 gene consisting of SEQ ID : NO. 1; and (b) introducing the expression vector into a plant cell to prepare a transformant over-expressing the OsWRKY6 gene. A transformant is transformed by the expression vector pB2GW7-OsWRKY6, wherein the transformant is selected from the group consisting of a rice cell, a cabbage cell, a hot pepper cell, a potato cell and a rape cell. Further, the plant diseases are selected from a group consisting of Bacterial blight, rice blast disease, Rice stripe tenuivirus, Rhizoctonia solani, Rice Black-Streaked Dwarf Virus and Mycosphaerella leaf spot.
