Cotton alpha-globulin promoter for seed-specific expression of transgenes

An isolated nucleic acid corresponding to an AG regulatory region which directs seed specific expression comprising the nucleotide sequence set forth in SEQ ID NO:2.

A method for obtaining a plant which produces at least one seed having a protein content different from a plant of the same species not treated by this method, said method comprising:

• transforming a host plant cell with a DNA construct, wherein said construct comprises, as operably linked components, an alpha globulin gene regulatory region, and a DNA sequence encoding a protein, wherein said components are functional in a plant cell.

A method for obtaining a plant which produces at least one seed having a protein content different from a plant of the same species not treated by this method, said method comprising:

• transforming a host plant cell with a RNA or DNA, wherein said construct comprises, as operably linked components, an alpha globulin gene regulatory region, and an RNA or DNA sequence encoding a protein, wherein said components are functional in a plant cell.

A method for altering expression of a protein in a cell of a plant which produces at least one seed compared to a cell of a plant of the same species not treated by this method, said method comprising:

• transferring an RNA construct to a host plant cell, wherein said construct comprises, as operably linked components, an alpha globulin gene regulatory region, and an RNA sequence that drives the transcription of an RNA that is complementary to an endogenous RNA encoding a protein, whereby expression of said endogenous protein is altered.
