This invention relates to a DNA fragment comprising a base sequence (a) the base sequence referred to as nucleotide numbers 1-3794 in a sequence number 1 in a sequence list; (b) the base sequence (a) a part of which is deleted or substituted by another base sequence, or to which another base sequence is added. Further, the invention relates to a recombinant DNA and transformed plant including the above fragment. Moreover, the invention relates to fragment developing a promoter activity with a responsive property to low temperatures which comprises a base sequence (c) the base sequence referred to as nucleotide numbers 1-2797 in a sequence number 1 in a sequence list; (d) A part of the base sequence (c) developing a promoter activity with a responsive property to low temperatures; or (e) The base sequence (c) or (d) a part of which is deleted or substituted by another base sequence, or to which another base sequence is added. Further, the invention relates to a recombinant DNA and transformed plant including the above fragment.
