摘要： 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.
