Identification of a gene from monocotyledonous plants such as rice, which codes for a transcription factor specific to a stress tolerant gene and provision of a novel environmental stress tolerant plant using the gene. From the rice genome, a gene, which binds to a cis element existing upstream of the gene encoding a stress responsive protein and for a transcription factor to activate the transcription of the gene, is identified. Further, the gene of the transcription factor is used to transform a plant, thereby improving tolerance against environmental stresses such as low temperature, dehydration, and salt stresses.

Genes encoding plant transcription factors

The present invention relates to an environmental stress-tolerant plant. The invention discloses a transgenic plant containing a gene in which a DNA encodes a protein consisting of the amino acid sequence as shown in SEQ ID NO: 4 with the deletion of amino acids from positions 136-165 thereof, the DNA being operably linked downstream of a stress responsive promoter.
