Osmotic stress-inducible protein functioning as a negative regulator in osmotic stress signaling pathway of plants

摘要

The present invention relates to an AtSIK protein functioning as a negative regulator to the osmotic stress-inducible gene and more particularly to a gene encoding said protein. Said AtSIK protein isolated from Arabidopsis thaliana acts as a negative regulator to the osmotic stress-inducible gene. Therefore, a plant having enhanced resistance to osmotic stress can be produced by inhibiting expression of AtSIK and consequently, the productivity of the plant can be increased.
