GENE ENCODING PEPPER TRANSCRIPTION FACTOR CAWRKY1 HAVING RESISTANCE TO FROST DAMAGE AND DROUGHT DISASTER, AND USE THEREOF

摘要

PURPOSE: A transgenic plant which is transformed by a freezing injury and drought tolerant gene is provided to improve freezing injury and drought tolerance, and to remarkably improve productivity of Solanaceae. CONSTITUTION: A method for improving freezing injury and drought tolerance in a plant comprises a step of overexpressing a polypeptide with an amino acid sequence of sequence number 2. The polypeptide is overexpressed by transforming a recombinant expression vector containing a promoter and a gene encoding the polypeptide in a plant or by introducing the gene into a plant cell. The gene encoding the polypeptide has a base sequence of sequence number 1. The plant includes potato, tomato, Capsicum annuum, bean, eggplant, or tobacco. A method for producing a plant with freezing injury and drought tolerance comprises a step of transforming the recombinant expression vector to the plant. A transformant with improved freezing injury and drought tolerance is obtained by transforming with the recombinant expression vector.
