## Abstract

The present invention relates to a composition for improving a tolerance to a salt stress or a drought stress of a plant, and a method for preparing transformed plant exhibiting improved tolerance to salt stress or drought stress. The nucleotide sequences of the present invention are involved in salt or drought stress-tolerance, therefore may be effectively used for cultivating the plants with novel functional features which are less affected by climates and environments of the cultivated areas.

## Claims

### Claim 1

A method for preparing transformed Arabidopsis thaliana exhibiting improved tolerance to a salt stress, the method comprising:
(a) introducing a transformation vector into the AtSRG1 gene, wherein the transformation vector inhibits an expression of a nucleotide sequence encoding the amino acid sequence consisting of SEQ ID NO:3 into a Arabidopsis thaliana cell;
(b) obtaining the transformed Arabidopsis thaliana exhibiting improved salt stress tolerance from the Arabidopsis thaliana cell of (a); and
(c) growing the transformed Arabidopsis thaliana under a salt stress condition.

### Claim 2

A method for improving a tolerance to a salt stress of Arabidopsis thaliana, the method comprising:
(a) introducing a transformation vector into the AtSRG1 gene, wherein the transformation vector inhibits an expression of a nucleotide sequence encoding the amino acid sequence consisting of SEQ ID NO:3 into a cell of the Arabidopsis thaliana;
(b) obtaining a transgenic Arabidopsis thaliana exhibiting improved tolerance to a salt stress from the cell of the Arabidopsis thaliana; and
(c) growing the transgenic Arabidopsis thaliana under a salt stress condition.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the nucleotide sequence encoding the amino acid sequence of SEQ ID NO:3 is the nucleotide sequence of SEQ ID NO:1.

### Claim 4 (depends on 2)

The method according to claim 2, wherein the transformation vector is T-DNA.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the nucleotide sequence encoding the amino acid sequence of SEQ ID NO:3 is the nucleotide sequence of SEQ ID NO:1.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the transformation vector is T-DNA.
