Patent ID: 7902423

Claim:
An expression cassette for regulating seed-specific or seed-preferential expression in plants comprising a) at least one transcription regulating nucleotide sequence of a Linum usitatissimum tonoplast intrinsic protein gene, wherein the at least one transcription regulating nucleotide sequence drives seed-specific or seed-preferential expression and is selected from the group of sequences consisting of i) the sequence described by SEQ ID NO: 6, 7, or 8, ii) a fragment of at least 250 consecutive bases of the sequence described by SEQ ID NO: 6, 7, or 8, and iii) a nucleotide sequence having at least 90% sequence identity to SEQ ID NO: 6, 7, or 8, and functionally linked thereto b) at least one nucleic acid sequence which is heterologous in relation to said at least one transcription regulating nucleotide sequence.
