The present invention relates to a method for increasing resistance of monocot plants against abiotic stress which comprises a step of transforming monocot plants with a recombinant plasmid containing a fused gene (TPSP) of trehalose-6-phosphate synthetase (TPS) gene and trehalose-6-phosphate phosphatase (TPP) gene to express the TPSP gene while maintaining normal growth and development characteristics. The present invention can increase the resistance of monocot plants against various stresses so that it can greatly contribute to the improvement of production and quality of valuable agricultural crops. The present invention also relates to a transgenic monocot plant, plant cell, or protoplast transformed with a nucleic acid encoding an enzyme for trehalose biosynthesis, under control of an inducible promoter, that increases tolerance to low temperature, salt, and water stress.

The present invention relates to proteins, OsHDAC1, OsHDAC2 and OsHDAC3, which function as histone deacetylase, a gene coding for said proteins, and a method for producing a plant having a high growth rate by expressing said gene in the plant. According to the present invention, the OsHDACs proteins change the structure of chromatin to increase or decrease the expression of a foreign gene in the genomes, so that the expression amount of the OsHDACs proteins can be controlled to produce a plant having varied phenotypic characteristics. Particularly, the OsHDAC1 protein is expressed locally in the plant and increases the growth rate of plant by its overexpression and its expression is increased by ABA. Therefore, this protein can be very efficiently used for producing plants having a high growth rate even under stress conditions including drought, cold, etc., as well as under normal conditions.
