ABSTRACT:
An object of the present invention is to provide a novel DNA sequence having a flower organ-specific promoter activity which makes it possible to express a foreign gene specifically in pistil or lodicule, this enabling genetic manipulation. The present invention provides a DNA fragment comprising the sequence of positions 1 to 5369 in the nucleotide sequence represented by SEQ ID NO:3 in Sequence Listing, the sequence of positions 3335 to 5108 therein, a part of these sequences or a sequence derived from these sequences by deletion, substitution, insertion or addition of one or more nucleotides and having a promoter activity; and a flower organ-specific promoter sequence which can be identified from among sequences obtained by screening a genomic library of rice or other plants by using as a probe the nucleotide sequence as described above or a part thereof.
