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.times.SSC at 42.degree. 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.
