Novel cold-inducible promoters which are induced in potato tuber at low temperatures but scarcely induced in organs other than tuber or at ordinary temperatures and can sustain the expression for a prolonged period of time, i.e., five months or longer. These promoters include a sequence consisting of the first to 3546-th bases in the base sequence represented by SEQ ID NO:1 in the Sequence Listing, a part of the same having a cold-inducible promoter activity, DNA sequences having a cold-inducible promoter activity wherein one or more nucleotides have been deleted, substituted, inserted or added to these sequences, a sequence consisting of the first to 4120-th bases in the base sequence represented by SEQ ID NO:2 in the Sequence Listing, a part of the same having a cold-inducible promoter activity and DNA sequences having a coldinducible promoter activity wherein one or more nucleotides have been deleted, substituted, inserted or added to these sequences. |
