Patent ID: 7148401

Claim:
A method for regulating gene expression in a plant, said method comprising the steps of: (a) transforming at least one cell of a plant with an expression cassette comprising a promoter operably linked to a polynucleotide of interest, wherein the promoter is a nucleic acid molecule comprising the nucleotide sequence set forth in SEQ ID NO:1; and (b) regenerating said transformed cell into a transformed plant; wherein said promoter drives the expression of said polynucleotide of interest preferentially in elongating tissues of said plant, said elongating tissues selected from the group consisting of the elongating tissues of stems, tassels, and silks, or wherein said promoter drives the expression of said polynucleotide of interest in a part of said plant selected from the group consisting of a vascular bundle, cells surrounding a vascular bundle, a pulvinus, a leaf sheath, a root cap, a stalk internode, and a nodal plate.
