A novel promoter having an expression activity specific to one of pistil tissues. This promoter has the DNA sequence of the 1- to 2595-positions of the sequence of SEQ ID NO:1, the DNA sequence of the 1- to 2322-positions of the sequence of SEQ ID NO:2, the DNA sequence of the 1- to 2012-positions of the sequence of SEQ ID NO:3, or a part thereof. A method for constructing a transgenic plant comprising transferring into a plant a foreign gene which has been ligated to the above promoter in an operable manner and a transgenic plant having been modified thereby.

L'invention concerne un nouveau promoteur exerçant une activité spécifique sur l'un des tissus du pistil. Ce promoteur possède la séquence d'ADN des positions 1 à 2595 de la séquence SEQ ID N· : 1, la séquence d'ADN des positions 1 à 2322 de la séquence SEQ ID N· : 2, la séquence d'ADN des positions 1 à 2012 de la séquence SEQ ID N· : 3, ou une partie afférente. L'invention concerne également une méthode d'élaboration d'une plante transgénique consistant à transférer dans une plante un gène étranger ayant subi une ligature avec le promoteur selon l'invention, de manière fonctionnelle, ainsi qu'une plante transgénique modifiée de cette manière.
