| 摘要 |
Novel DNA sequences having a flower organ-specific promoter activity which allow the expression of a foreign gene in pistil or lodicule and thus enable genetic engineering manipulations thereof. DNA fragments having the base sequence consisting of the 1- to 5369-bases and the base sequence consisting of the 3335- to 5108-bases, in the base sequence represented by SEQ ID NO:2 in the sequence listing, or sequences derived therefrom by deletion, substitution, insertion or addition of one or more nucleotides in these sequences and having the promoter activity; and flower organ-specific promoter sequences which can be specified by sequences obtained from genome libraries derived from rice or other plants by using the above base sequences or parts thereof as a probe. |
