Abstract:
1. An expression cassette for regulating vascular tissue-preferential or vascular tissue-specific expression in plants comprising i) at least one transcription regulating nucleotide sequence, and ii) at least one nucleic acid sequence which is operably linked to and heterologous in relation to said transcription regulating nucleotide sequence, wherein the transcription regulating nucleotide sequence comprises the nucleotide sequence described by SEQ ID NOs: 1, 2, 3, 4, or 5, or a fragment thereof having the same promoter activity as the nucleotide sequence of SEQ ID NO: 1, 2, 3, 4, or 5, wherein the transcription regulating nucleotide sequence directs vascular tissue-preferential or vascular tissue-specific transcription of the operably linked nucleic acid sequence in a plant cell.
