Method for enhancing drought stress resistance of plant using LEA gene

摘要

PURPOSE: A method for improving drought stress resistance of a plant is provided to enable a transgenic plant to grow into a drought resistant race and to stably supply agricultural products. CONSTITUTION: A method for improving drought resistance of a plant comprises a step of overexpressing a protein with an amino acid sequence of sequence number 2 and improving drought resistance. A method for overexpressing the protein comprises: a step of transforming a plant with a recombinant expression vector containing a promoter and a gene encoding the protein or a step of transducing the gene into a plant cell. The gene has a base sequence of sequence number 1. The promoter is inducible RD29A promoter. The plant includes potato, barley, corn, wheat, rye, grass, sugar cane, or onion. The recombinant expression vector is pBINRD29A vector.
