Novel transcriptional factor enhancing the resistance of plants to osmotic stress

Abstract

The present invention relates to a transcription factor of a plant, AtSIZ, induced by osmotic stress; a gene encoding said transcription factor; and a method for enhancing resistance to stress of a plant by using said gene. Said AtSIZ protein isolated from Arabidopsis thaliana is a polypeptide, which contains C3H type zinc finger motif and acts as a transcription regulation factor activating transcription of genes related to stress response of a plant. Therefore, a plant with the enhanced resistance to osmotic stress can be produced by overexpressing said genes in the plant through transforming recombinant plasmid containing AtSIZ gene into a plant and consequently, the productivity of the plant can be increased.
