Cassava vein mosaic virus promoters nucleic acid sequences and expression vectors

A transgenic plant comprising a promoter nucleotide sequence that is capable of initiating transcription of an operably linked heterologous nucleic acid sequence in a plant cell wherein said promoter nucleotide sequence has at least 80% identity to 18 sequential nucleotides of the cassava vein mosaic virus (CsVMV) promoter shown in SEQ ID NO 3 (pA) and is operatively linked to said heterologous nucleic acid sequence.

11-15. (canceled)

A transgenic plant comprising a CsVMV promoter nucleotide sequence and a heterologous nucleotide sequence, wherein said CsVMV promoter nucleotide sequence and said heterologous nucleotide sequence are operatively linked, and wherein said CsVMV promoter nucleotide sequence initiates transcription of said heterologous nucleic acid sequence in a cell of said transgenic plant.

A transgenic plant comprising a CsVMV promoter nucleotide sequence, wherein said CsVMV promoter nucleotide sequence consists essentially of SEQ ID NO:3 or a fragment thereof having promoter activity.

A transgenic plant comprising a CsVMV promoter nucleotide sequence, wherein said CsVMV promoter nucleotide sequence does not include a naturally occurring CsVMV genomic sequence adjacent to said CsVMV promoter nucleotide sequence.

A transgenic plant comprising a recombinant CsVMV promoter nucleotide sequence.
