Abstract: The present invention provides a method for improving the tolerance of a plant to an abiotic stress and a method for promoting growing of a plant, comprising a nucleotide sequence encoding the AtSRP (Arabidopsis thaliana stress related protein) of a plant. The present nucleotide sequence is involved in abiotic stress tolerance such as drought, low-temperature and salt stresses of plants. Therefore, the overexpressing transgenic plants have excellent tolerances to these abiotic stresses, whereby they may be useful as novel functional crops which are affected by climates and environments of the cultivated areas. In addition, where the plants are transformed with the present nucleotide sequence, the growth abilities of the transgenic plants are remarkably enhanced, whereby they may effectively used for cultivating the plants with novel function of rapid growing, and biomass.
