Abstract
The present invention provides methods for inducing tissue-specific expression, which includes preparing an expression vector having a promoter. The promoter includes any one of the following DNAs (a) to (c): (a) a DNA, which includes the nucleotide sequence shown in SEQ ID NO: 1; (b) a DNA, which includes the nucleotide sequence ranging from nucleotides 1344 to 2843 of SEQ ID NO: 1; and (c) a DNA, which is a DNA fragment that can hybridize under stringent conditions to a DNA fragment including a nucleotide sequence fully complementary to the nucleotide sequence shown in SEQ ID NO: 1, wherein (a), (b) or (c) can control the transcription of a coding sequence located downstream thereof; and wherein the stringent conditions are 5×SSC at 42° C.; The expression vector, also, includes a coding sequence located downstream of the promoter. Additionally, the method includes introducing the expression vector into a plant cell to obtain a transgenic plant; wherein the promoter activity is lower in mature seeds or root bases than in plant tissues other than mature seeds or root bases. The present invention also provides transformants containing a promoter; the promoter includes any of the DNAs (a) to (c) described above.
