Method for improving the resistance to cold stress using ABA receptor RCAR5 in plants

摘要

The present invention relates to an Arabidopsis thaliana abcisic acid receptor RCAR5 gene, a protein composed of an amino acid encoded by the gene, and a method for enhancing low temperature stress resistance of plants using the gene or protein, and RCAR5 functions as a positive regulator of ABA signaling. It was confirmed that the effect of increasing the resistance to low temperature stress in the transgenic plant overexpressing the protein was confirmed, and it can be used for improvement of crops that can be used by humans through the regulation of the expression of the RCAR5 gene, and in particular, it can be usefully used to improve the productivity of plants. It is expected to be possible.
